feat: webauthn (#2707)
This implements Webauthn. Old devices can be used to authenticate via the appid compatibility layer which should be automatic. New devices will be registered via Webauthn, and devices which do not support FIDO2 will no longer be able to be registered. At this time it does not fully support multiple devices (backend does, frontend doesn't allow registration of additional devices). Does not support passwordless.

# Authelia Configuration #
###############################################################################
## Note: the container by default expects to find this file at /config/configuration.yml.
## Certificates directory specifies where Authelia will load trusted certificates (public portion) from in addition to
## the system certificates store.
## They should be in base64 format, and have one of the following extensions: *.cer, *.crt, *.pem.
# certificates_directory: /config/certificates/
## The theme to display: light, dark, grey, auto.
theme: light
## The secret used to generate JWT tokens when validating user identity by email confirmation. JWT Secret can also be
## set using a secret: https://www.authelia.com/docs/configuration/secrets.html
jwt_secret: a_very_important_secret
## Default redirection URL
##
## If user tries to authenticate without any referer, Authelia does not know where to redirect the user to at the end
## of the authentication process. This parameter allows you to specify the default redirection URL Authelia will use
## in such a case.
##
## Note: this parameter is optional. If not provided, user won't be redirected upon successful authentication.
default_redirection_url: https://home.example.com/
##
## Server Configuration
##
server:
## The address to listen on.
host: 0.0.0.0

algorithm: sha1
## The number of digits a user has to input. Must either be 6 or 8.
## Changing this option only affects newly generated TOTP configurations.
## It is CRITICAL you read the documentation before changing this option:
## https://www.authelia.com/docs/configuration/one-time-password.html#digits
digits: 6
## The period in seconds a one-time password is valid for.
## Changing this option only affects newly generated TOTP configurations.
period: 30
## The skew controls number of one-time passwords either side of the current one that are valid.
## Warning: before changing skew read the docs link below.
skew: 1
## See: https://www.authelia.com/docs/configuration/one-time-password.html#input-validation to read the documentation.
##
## WebAuthn Configuration
##
## Parameters used for WebAuthn.
webauthn:
## Disable Webauthn.
disable: false
## Adjust the interaction timeout for Webauthn dialogues.
timeout: 60s

##
## Duo Push API Configuration
##
## Parameters used to contact the Duo API. Those are generated when you protect an application of type
## "Partner Auth API" in the management panel.
duo_api:
hostname: api-123456789.example.com
integration_key: ABCDEF
## Secret can also be set using a secret: https://www.authelia.com/docs/configuration/secrets.html
secret_key: 1234567890abcdefghifjkl
enable_self_enrollment: false
##
## NTP Configuration
##
## This is used to validate the servers time is accurate enough to validate TOTP.
ntp:
## NTP server address.
address: "time.cloudflare.com:123"
## NTP version.
version: 4
## Maximum allowed time offset between the host and the NTP server.
max_desync: 3s
## Disables the NTP check on startup entirely. This means Authelia will not contact a remote service at all if you
## set this to true, and can operate in a truly offline mode.
disable_startup_check: false
## The default of false will prevent startup only if we can contact the NTP server and the time is out of sync with
## the NTP server more than the configured max_desync. If you set this to true, an error will be logged but startup
## will continue regardless of results.
disable_failure: false
##
## Authentication Backend Provider Configuration
##
## Used for verifying user passwords and retrieve information such as email address and groups users belong to.
##
## The available providers are: `file`, `ldap`. You must use only one of these providers.
authentication_backend:
## Disable both the HTML element and the API for reset password functionality.
disable_reset_password: false
## The amount of time to wait before we refresh data from the authentication backend. Uses duration notation.
## To disable this feature set it to 'disable', this will slightly reduce security because for Authelia, users will
## always belong to groups they belonged to at the time of login even if they have been removed from them in LDAP.
## To force update on every request you can set this to '0' or 'always', this will increase processor demand.
## See the below documentation for more information.
## Duration Notation docs: https://www.authelia.com/docs/configuration/index.html#duration-notation-format
## Refresh Interval docs: https://www.authelia.com/docs/configuration/authentication/ldap.html#refresh-interval
refresh_interval: 5m
##
## LDAP (Authentication Provider)
##
## This is the recommended Authentication Provider in production
## because it allows Authelia to offload the stateful operations
## onto the LDAP service.
ldap:
## The LDAP implementation, this affects elements like the attribute utilised for resetting a password.
## Acceptable options are as follows:
## - 'activedirectory' - For Microsoft Active Directory.
## - 'custom' - For custom specifications of attributes and filters.
## This currently defaults to 'custom' to maintain existing behaviour.
##
## Depending on the option here certain other values in this section have a default value, notably all of the
## attribute mappings have a default value that this config overrides, you can read more about these default values
## at https://www.authelia.com/docs/configuration/authentication/ldap.html#defaults
implementation: custom
## The url to the ldap server. Format: <scheme>://<address>[:<port>].
## Scheme can be ldap or ldaps in the format (port optional).
url: ldap://127.0.0.1
## The dial timeout for LDAP.
timeout: 5s
## Use StartTLS with the LDAP connection.
start_tls: false
tls:
## Server Name for certificate validation (in case it's not set correctly in the URL).
# server_name: ldap.example.com
## Skip verifying the server certificate (to allow a self-signed certificate).
## In preference to setting this we strongly recommend you add the public portion of the certificate to the
## certificates directory which is defined by the `certificates_directory` option at the top of the config.
skip_verify: false
## Minimum TLS version for either Secure LDAP or LDAP StartTLS.
minimum_version: TLS1.2
## The distinguished name of the container searched for objects in the directory information tree.
## See also: additional_users_dn, additional_groups_dn.
base_dn: dc=example,dc=com
## The attribute holding the username of the user. This attribute is used to populate the username in the session
## information. It was introduced due to #561 to handle case insensitive search queries. For you information,
## Microsoft Active Directory usually uses 'sAMAccountName' and OpenLDAP usually uses 'uid'. Beware that this
## attribute holds the unique identifiers for the users binding the user and the configuration stored in database.
## Therefore only single value attributes are allowed and the value must never be changed once attributed to a user
## otherwise it would break the configuration for that user. Technically, non-unique attributes like 'mail' can also
## be used but we don't recommend using them, we instead advise to use the attributes mentioned above
## (sAMAccountName and uid) to follow https://www.ietf.org/rfc/rfc2307.txt.
# username_attribute: uid
## The additional_users_dn is prefixed to base_dn and delimited by a comma when searching for users.
## i.e. with this set to OU=Users and base_dn set to DC=a,DC=com; OU=Users,DC=a,DC=com is searched for users.
additional_users_dn: ou=users
## The users filter used in search queries to find the user profile based on input filled in login form.
## Various placeholders are available in the user filter which you can read about in the documentation which can
## be found at: https://www.authelia.com/docs/configuration/authentication/ldap.html#users-filter-replacements
##
## Recommended settings are as follows:
## - Microsoft Active Directory: (&({username_attribute}={input})(objectCategory=person)(objectClass=user))
## - OpenLDAP:
## - (&({username_attribute}={input})(objectClass=person))
## - (&({username_attribute}={input})(objectClass=inetOrgPerson))
##
## To allow sign in both with username and email, one can use a filter like
## (&(|({username_attribute}={input})({mail_attribute}={input}))(objectClass=person))
users_filter: (&({username_attribute}={input})(objectClass=person))
## The additional_groups_dn is prefixed to base_dn and delimited by a comma when searching for groups.
## i.e. with this set to OU=Groups and base_dn set to DC=a,DC=com; OU=Groups,DC=a,DC=com is searched for groups.
additional_groups_dn: ou=groups
## The groups filter used in search queries to find the groups based on relevant authenticated user.
## Various placeholders are available in the groups filter which you can read about in the documentation which can
## be found at: https://www.authelia.com/docs/configuration/authentication/ldap.html#groups-filter-replacements
##
## If your groups use the `groupOfUniqueNames` structure use this instead:
## (&(uniqueMember={dn})(objectClass=groupOfUniqueNames))
groups_filter: (&(member={dn})(objectClass=groupOfNames))
## The attribute holding the name of the group.
# group_name_attribute: cn
## The attribute holding the mail address of the user. If multiple email addresses are defined for a user, only the
## first one returned by the LDAP server is used.
# mail_attribute: mail
## The attribute holding the display name of the user. This will be used to greet an authenticated user.
# display_name_attribute: displayName
## The username and password of the admin user.
user: cn=admin,dc=example,dc=com
## Password can also be set using a secret: https://www.authelia.com/docs/configuration/secrets.html
password: password
##
## File (Authentication Provider)
##
## With this backend, the users database is stored in a file which is updated when users reset their passwords.
## Therefore, this backend is meant to be used in a dev environment and not in production since it prevents Authelia
## to be scaled to more than one instance. The options under 'password' have sane defaults, and as it has security
## implications it is highly recommended you leave the default values. Before considering changing these settings
## please read the docs page below:
## https://www.authelia.com/docs/configuration/authentication/file.html#password-hash-algorithm-tuning
##
## Important: Kubernetes (or HA) users must read https://www.authelia.com/docs/features/statelessness.html
##
# file:
# path: /config/users_database.yml
# password:
# algorithm: argon2id
# iterations: 1
# key_length: 32
# salt_length: 16
# memory: 1024
# parallelism: 8
##
## Access Control Configuration
##
## Access control is a list of rules defining the authorizations applied for one resource to users or group of users.
##
## If 'access_control' is not defined, ACL rules are disabled and the 'bypass' rule is applied, i.e., access is allowed
## to anyone. Otherwise restrictions follow the rules defined.
##
## Note: One can use the wildcard * to match any subdomain.
## It must stand at the beginning of the pattern. (example: *.mydomain.com)
##
## Note: You must put patterns containing wildcards between simple quotes for the YAML to be syntactically correct.
##
## Definition: A 'rule' is an object with the following keys: 'domain', 'subject', 'policy' and 'resources'.
##
## - 'domain' defines which domain or set of domains the rule applies to.
##
## - 'subject' defines the subject to apply authorizations to. This parameter is optional and matching any user if not
## provided. If provided, the parameter represents either a user or a group. It should be of the form
## 'user:<username>' or 'group:<groupname>'.
##
## - 'policy' is the policy to apply to resources. It must be either 'bypass', 'one_factor', 'two_factor' or 'deny'.
##
## - 'resources' is a list of regular expressions that matches a set of resources to apply the policy to. This parameter
## is optional and matches any resource if not provided.
##
## Note: the order of the rules is important. The first policy matching (domain, resource, subject) applies.
access_control:
## Default policy can either be 'bypass', 'one_factor', 'two_factor' or 'deny'. It is the policy applied to any
## resource if there is no policy to be applied to the user.
default_policy: deny
networks:
- name: internal
networks:
- 10.10.0.0/16
- 192.168.2.0/24
- name: VPN
networks: 10.9.0.0/16
rules:
## Rules applied to everyone
- domain: public.example.com
policy: bypass
- domain: secure.example.com
policy: one_factor
## Network based rule, if not provided any network matches.
networks:
- internal
- VPN
- 192.168.1.0/24
- 10.0.0.1
- domain:
- secure.example.com
- private.example.com
policy: two_factor
- domain: singlefactor.example.com
policy: one_factor
## Rules applied to 'admins' group
- domain: "mx2.mail.example.com"
subject: "group:admins"
policy: deny
- domain: "*.example.com"
subject:
- "group:admins"
- "group:moderators"
policy: two_factor
## Rules applied to 'dev' group
- domain: dev.example.com
resources:
- "^/groups/dev/.*$"
subject: "group:dev"
policy: two_factor
## Rules applied to user 'john'
- domain: dev.example.com
resources:
- "^/users/john/.*$"
subject: "user:john"
policy: two_factor
## Rules applied to user 'harry'
- domain: dev.example.com
resources:
- "^/users/harry/.*$"
subject: "user:harry"
policy: two_factor
## Rules applied to user 'bob'
- domain: "*.mail.example.com"
subject: "user:bob"
policy: two_factor
- domain: "dev.example.com"
resources:
- "^/users/bob/.*$"
subject: "user:bob"
policy: two_factor
##
## Session Provider Configuration
##
## The session cookies identify the user once logged in.
## The available providers are: `memory`, `redis`. Memory is the provider unless redis is defined.
session:
## The name of the session cookie.
name: authelia_session
## The domain to protect.
## Note: the authenticator must also be in that domain.
## If empty, the cookie is restricted to the subdomain of the issuer.
domain: example.com
## Sets the Cookie SameSite value. Possible options are none, lax, or strict.
## Please read https://www.authelia.com/docs/configuration/session/#same_site
same_site: lax
## The secret to encrypt the session data. This is only used with Redis / Redis Sentinel.
## Secret can also be set using a secret: https://www.authelia.com/docs/configuration/secrets.html
secret: insecure_session_secret
## The value for expiration, inactivity, and remember_me_duration are in seconds or the duration notation format.
## See: https://www.authelia.com/docs/configuration/index.html#duration-notation-format
## All three of these values affect the cookie/session validity period. Longer periods are considered less secure
## because a stolen cookie will last longer giving attackers more time to spy or attack.
## The time before the cookie expires and the session is destroyed if remember me IS NOT selected.
expiration: 1h
## The inactivity time before the session is reset. If expiration is set to 1h, and this is set to 5m, if the user
## does not select the remember me option their session will get destroyed after 1h, or after 5m since the last time
## Authelia detected user activity.
inactivity: 5m
## The time before the cookie expires and the session is destroyed if remember me IS selected.
## Value of 0 disables remember me.
remember_me_duration: 1M
##
## Redis Provider
##
## Important: Kubernetes (or HA) users must read https://www.authelia.com/docs/features/statelessness.html

database_index: 0
## The maximum number of concurrent active connections to Redis.
maximum_active_connections: 8
## The target number of idle connections to have open ready for work. Useful when opening connections is slow.
minimum_idle_connections: 0
## The Redis TLS configuration. If defined will require a TLS connection to the Redis instance(s).
# tls:
## Server Name for certificate validation (in case you are using the IP or non-FQDN in the host option).
# server_name: myredis.example.com
## Skip verifying the server certificate (to allow a self-signed certificate).
## In preference to setting this we strongly recommend you add the public portion of the certificate to the
## certificates directory which is defined by the `certificates_directory` option at the top of the config.
# skip_verify: false
## Minimum TLS version for the connection.
# minimum_version: TLS1.2
## The Redis HA configuration options.
## This provides specific options to Redis Sentinel, sentinel_name must be defined (Master Name).
# high_availability:
## Sentinel Name / Master Name.
# sentinel_name: mysentinel
## Specific username for Redis Sentinel. The node username and password is configured above.
# sentinel_username: sentinel_specific_user
## Specific password for Redis Sentinel. The node username and password is configured above.
# sentinel_password: sentinel_specific_pass
## The additional nodes to pre-seed the redis provider with (for sentinel).
## If the host in the above section is defined, it will be combined with this list to connect to sentinel.
## For high availability to be used you must have either defined; the host above or at least one node below.
# nodes:
# - host: sentinel-node1
# port: 6379
# - host: sentinel-node2
# port: 6379
## Choose the host with the lowest latency.
# route_by_latency: false
## Choose the host randomly.
# route_randomly: false
##
## Regulation Configuration
##
## This mechanism prevents attackers from brute forcing the first factor. It bans the user if too many attempts are made
## in a short period of time.
regulation:
## The number of failed login attempts before user is banned. Set it to 0 to disable regulation.
max_retries: 3
## The time range during which the user can attempt login before being banned. The user is banned if the
## authentication failed 'max_retries' times in a 'find_time' seconds window. Find Time accepts duration notation.
## See: https://www.authelia.com/docs/configuration/index.html#duration-notation-format
find_time: 2m
## The length of time before a banned user can login again. Ban Time accepts duration notation.
## See: https://www.authelia.com/docs/configuration/index.html#duration-notation-format

##
## Storage Provider Configuration
##
## The available providers are: `local`, `mysql`, `postgres`. You must use one and only one of these providers.
storage:
## The encryption key that is used to encrypt sensitive information in the database. Must be a string with a minimum
## length of 20. Please see the docs if you configure this with an undesirable key and need to change it.

##
# filesystem:
# filename: /config/notification.txt
##
## SMTP (Notification Provider)
##
## Use a SMTP server for sending notifications. Authelia uses the PLAIN or LOGIN methods to authenticate.
## [Security] By default Authelia will:
## - force all SMTP connections over TLS including unauthenticated connections
## - use the disable_require_tls boolean value to disable this requirement
## (only works for unauthenticated connections)
## - validate the SMTP server x509 certificate during the TLS handshake against the hosts trusted certificates
## (configure in tls section)

## The sender is used to is used for the MAIL FROM command and the FROM header.
## If this is not defined and the username is an email, we use the username as this value. This can either be just
## an email address or the RFC5322 'Name <email address>' format.
sender: "Authelia <admin@example.com>"
## HELO/EHLO Identifier. Some SMTP Servers may reject the default of localhost.
identifier: localhost
## Subject configuration of the emails sent. {title} is replaced by the text from the notifier.
subject: "[Authelia] {title}"
## This address is used during the startup check to verify the email configuration is correct.
## It's not important what it is except if your email server only allows local delivery.
startup_check_address: test@authelia.com
## By default we require some form of TLS. This disables this check though is not advised.
disable_require_tls: false
## Disables sending HTML formatted emails.
disable_html_emails: false
tls:
## Server Name for certificate validation (in case you are using the IP or non-FQDN in the host option).
# server_name: smtp.example.com
## Skip verifying the server certificate (to allow a self-signed certificate).
