System Settings

These settings are similar to the configuration options listed here, however they can only be adjusted through the authentik Admin interface or API.


Configure how authentik should show avatars for users. Following values can be set:

Default: gravatar,initials

  • none: Disables per-user avatars and just shows a 1x1 pixel transparent picture

  • gravatar: Uses gravatar with the user's email address

  • initials: Generated avatars based on the user's name

  • Any URL: If you want to use images hosted on another server, you can set any URL.

    Additionally, these placeholders can be used:

    • %(username)s: The user's username
    • %(mail_hash)s: The email address, md5 hashed
    • %(upn)s: The user's UPN, if set (otherwise an empty string)

You can also use an attribute path like attributes.something.avatar, which can be used in combination with the file field to allow users to upload custom avatars for themselves.

Multiple modes can be set, and authentik will fallback to the next mode when no avatar could be found. For example, setting this to gravatar,initials will attempt to get an avatar from Gravatar, and if the user has not configured on there, it will fallback to a generated avatar.
