It would be nice if I could use an OAuth provider (e.g. Google, NextCloud etc) to authenticate users.
My use case would be having my Nextcloud on cloud.domain.tld and Polr on s.domain.tld. Users can login with their NextCloud credentials on both services (according to the OAuth2 flow).

Unfortunately I never worked with Laravel, only Yii2 so I'm little help with implementing this feature.
