- [OAuth2 Login on Standalone Wekan](https://github.com/wekan/wekan/wiki/OAuth2). For example, Rocket.Chat can provide OAuth2 login to Wekan.

Also, if you have Rocket.Chat using LDAP/SAML/Google/etc for logging into Rocket.Chat, then same users can login to Wekan when
  Rocket.Chat is providing OAuth2 login to Wekan.

Thanks to salleman33 and xet7 !

Closes #234
