Discourse Login No username, no email, no password.  
Public keys do not require a password.  
Since 2FA must be maintained on both the app and the website, it can prevent bot registration and avoid forgetting the public key.

Sign Up —\> Generate Public key —\> Bind 2FA TOTP

2FA is your password, 2FA as the first factor.

Login using public key+2FA.

## What do I need

I have registered more than 10 Discourse forums on Win10 browser and Android, such as F-droid, etc.

But I have forgotten my username and password, and my mail has been banned by the mail provider.
