2FA cannot be activated

I’ve just set up my forums account and proceeded to the security options, trying to activate 2FA for this account.

But whenever I scan the QR code with multiple Auth-Apps that all support basic TOTP, your website refuses to accept the entered six digit TOTP from the Auth-App, stating that “codes can only be used once”.

Given that I’ve tried entering each code for the very first time, that message doesn’t make any sense at all… I’d really appreciate if this could get looked into ASAP, as 2FA is absolutely, positively mandatory in this day and age.

Thank you for the report. We will investigate this.

As an update:

2FA activation still doesn’t work, still shows “Invalid authentication code. Each code can only be used once”.

Just in case this was internally thought to be resolved, it isn’t.
