Hi,
Im very new to Nextcloud. I have a webapp has a login page. It has own authentication system. But I want to use Nextcloud’s authentication to login my webapp. So I want to take the username and password from my webapp then send it to Nextcloud via http request to get a token or something useful result about successful login.
I checked out documentation but couldnt find any info about getting token with rest api.

Check out OIDC, you can configure your webapp to authorize users via Nextcloud.

E.g. I use it with gitea. Gitea will authorize users via Nextcloud.

## Description Would be cool if your own Nextcloud instance would work with Oau…th2/OIDC like requested by someone else here: https://discourse.gitea.io/t/nextcloud-as-an-oauth2-authentication-source/1119 When trying to do it with the generic OIDC it results in a 500 error as apparentl the .well-known stuff is not working. Details on the Nextcloud sinde of things can be found here: https://docs.nextcloud.com/server/16/admin_manual/configuration_server/oauth2.html Its a quite new feature and might not work quite like expected. Thanks for looking into it!

Thanks for reply. I found a kind of solution, i send 2 request to get ‘nc_token’; first request to get ‘requesttoken’ from response of http://xxx:8080/, then i use it in second http://xxx:8080/login post request body to get ‘nc_token’ from cookies. It is weird but ill find better solution i guess.
