> DokuWiki is a wiki application licensed under GPLv2 and written in the PHP programming language. It works on plain text files and thus does not need a database. Its syntax is similar to the one used by MediaWiki. It is often recommended as a more lightweight, easier to customize alternative to MediaWiki.
In the _Configuration Settings_ section in the _Administration_ interface navigate to _Authentication_ and activate _oauth_ in _Authentication backend_.
## authentik Configuration
### Provider
In authentik, under _Providers_, create an _OAuth2/OpenID Provider_ with these settings:
- Redirect URI: The _Callback URL / Redirect URI_ from _plugin»oauth»info_, usually `dokuwiki.company/doku.php`
- Signing Key: Select any available key
Note the _client ID_ and _client secret_, then save the provider. If you need to retrieve these values, you can do so by editing the provider.
### Application
In authentik, create an application which uses this provider. Optionally apply access restrictions to the application using policy bindings.
Set the Launch URL to the _Callback URL / Redirect URI_ (`dokuwiki.company/doku.php`).
