@staff => Hi @BrutalBirdie here with my new second account :'D (ping me on RocketChat to validate its me).
After enabling 2FA I get an NS_ERROR_REDIRECT_LOOP my main Account is a github login.
I will now try to enable 2FA for this account as well.
If I don't respond with this account within 10 minutes you can consider it also locked out by the error.
