Cannot register or sign in by any method except Google: `Unknown authentication strategy`

I'm trying to register on your platform using my email, but it seems your website doesn't allow that, although signing in with a username appears to be supported.

However, when I try to log in with a username, the server responds with code 500 and the following message:

An internal server error has occurred.
Error: Unknown authentication strategy "local"

When I try to log in via GitHub, it also responds with code 500 and the message:

An internal server error has occurred.
Error: Unknown authentication strategy "oauth2"

When I try to log in via Twitter, it also responds with code 500 and the message:

An internal server error has occurred.
Error: Unknown authentication strategy "twitter"

The only option that seems to work is signing in with Google. At least it opens the accounts.google.com page instead of returning code 500.
However, I haven't tried completing the Google login, so I cannot confirm whether it works or not.

Hi,

Right now we don't have a way to log in. SOON (in a couple months) we will.
Stay tuned.
