My phone went T**s up, and I had to do a hard reset.
I lost the settings for my 2FA (Google Authentication) for Mozilla, and I cannot find my on paper codes.
I can still login on my home laptop, but away from home, I need to use 2FA to login.
How would I reset/recover my 2FA?
I found it at https://accounts.firefox.com/settings/
Disable and then reenable 2fa, and then scan the barcode.
Saved the recovery codes.
