*Authelia* allows administrators to configure an enforced password policy.
## Configuration
```yaml
password_policy:
standard:
enabled: false
min_length: 8
max_length: 0
require_uppercase: false
require_lowercase: false
require_number: false
require_special: false
zxcvbn:
enabled: false
min_score: 3
```
## Options
### standard
This section allows you to enable standard security policies.
#### enabled
{{< confkey type="boolean" default="false" required="no" >}}
Enables standard password policy.
#### min_length
{{< confkey type="integer" default="8" required="no" >}}
Determines the minimum allowed password length.
#### max_length
{{< confkey type="integer" default="0" required="no" >}}
Determines the maximum allowed password length.
#### require_uppercase
{{< confkey type="boolean" default="false" required="no" >}}
Indicates that at least one UPPERCASE letter must be provided as part of the password.
#### require_lowercase
{{< confkey type="boolean" default="false" required="no" >}}
Indicates that at least one lowercase letter must be provided as part of the password.
#### require_number
{{< confkey type="boolean" default="false" required="no" >}}
Indicates that at least one number must be provided as part of the password.
#### require_special
{{< confkey type="boolean" default="false" required="no" >}}
Indicates that at least one special character must be provided as part of the password.
### zxcvbn
This password policy enables advanced password strength metering, using [zxcvbn](https://github.com/dropbox/zxcvbn).
Note that this password policy do not restrict the user's entry it just gives the user feedback as to how strong their
password is.
#### enabled
{{< confkey type="boolean" default="false" required="no" >}}
*__Important Note:__ only one password policy can be applied at a time.*
Enables zxcvbn password policy.
#### min_score
{{< confkey type="integer" default="3" required="no" >}}
Configures the minimum zxcvbn score allowed for new passwords. There are 5 levels in the zxcvbn score system (taken from
[github.com/dropbox/zxcvbn](https://github.com/dropbox/zxcvbn#usage)):
* score 0: too guessable: risky password (guesses < 10^3)
* score 1: very guessable: protection from throttled online attacks (guesses < 10^6)
* score 2: somewhat guessable: protection from unthrottled online attacks. (guesses < 10^8)
* score 3: safely unguessable: moderate protection from offline slow-hash scenario. (guesses < 10^10)
* score 4: very unguessable: strong protection from offline slow-hash scenario. (guesses >= 10^10)
We do not allow score 0, if you set the `min_score` value to 0 instead the default will be used instead.
