Authelia uses templates to generate the HTML and plaintext emails sent via the notification service. Each template has
two extensions; `.html` for HTML templates, and `.txt` for plaintext templates.
This guide effectively documents the usage of the
[template_path](../../configuration/notifications/introduction.md#template_path) notification configuration option.
## Template Names
| Template | Description |
|:--------------------:|:---------------------------------------------------------------------------------:|
| IdentityVerification | Used to render notifications sent when registering devices or resetting passwords |
| PasswordReset | Used to render notifications sent when password has successfully been reset |
For example, to modify the `IdentityVerification` HTML template, if your
[template_path](../../configuration/notifications/introduction.md#template_path) was configured as
`/config/email_templates`, you would create the `/config/email_templates/IdentityVerification.html` file to override the
HTML `IdentityVerification` template.
## Placeholder Variables
In template files, you can use the following placeholders which are automatically injected into the templates:
| Placeholder | Templates | Description |
|:--------------------:|:--------------------:|:----------------------------------------------------------------------------------------------------------------------------------------------:|
| `{{ .LinkURL }}` | IdentityVerification | The URL associated with the notification if applicable. |
| `{{ .LinkText }}` | IdentityVerification | The display value for the URL associated with the notification if applicable. |
| `{{ .Title }}` | All | A predefined title for the email. <br> It will be `"Reset your password"` or `"Password changed successfully"`, depending on the current step. |
| `{{ .DisplayName }}` | All | The name of the user, i.e. `John Doe` |
| `{{ .RemoteIP }}` | All | The remote IP address (client) that initiated the request or event. |
## Examples
This is a basic example:
```html
<body>
<h1>{{ .Title }}</h1>
Hi {{ .DisplayName }}<br/>
This email has been sent to you in order to validate your identity.
Click <a href="{{ .LinkURL }}">here</a> to change your password.
</body>
```
Some Additional examples for specific purposes can be found in the
[examples directory on GitHub](https://github.com/authelia/authelia/tree/master/examples/templates/notifications).
## Envelope Template
There is also a special envelope template. This is the email envelope which contains the content of the other templates
when sent via the SMTP notifier. It's *__strongly recommended__* that you do not modify this template unless you know
what you're doing. If you really want to modify it the name of the file must be `Envelope.tmpl`.
This template contains the following placeholders:
