Stand-alone accounts backend?

[poVoq]

This is a feature request / brainstorm how to best achieve a server side backend to securely store user accounts.

My assumption is that the Nextcloud php plugin might be suitable for conversion into a stand-alone backend?

Ideal feature set:

• Log-in website that checks against securely hashed user-names and passwords in a sql database
  • Should Oauth2 password-less login-flows be ever supported by a XMPP server, it would be great to add
• Registration website that writes securely hashed user-names and passwords to a sql database
  • Email password reset?
• Simple settings file to disable registrations and do some settings for JSXC (similar to the Nextcloud plugin)
• API end-point for token to use with xmpp-cloud-auth

Would it be good to include such a backend here in this repo, or create a separate one?
