Unable to log in into: crash-stats.mozilla.com

Hi want to login into crash-stats.mozilla.com but I get:

Error:

crash-stats.mozilla.com requires you to setup additional security measures for your account, such as enabling multi-factor authentication (MFA) or using a safer authentication method (such as a Firefox Account login). You will not be able to login until this is done.

I added a 2FA to my bugzilla account, but still could not log in.
I also tried to log in with my Firefox account (not sure whether this has 2FA), but this did not work as well.

Any suggestions on how to log in?
