When setting up 2fa. I scan the QR code. Enter the 6 digit pin generated by google authenticator. Download my backup codes and enter 1 when prompted then firefox says sync time and try again. I am running Ubuntu and have an android phone. Ubutu is set to automatic date. time and timezone. My phone is also set to automatic date&time. I have enabled seconds display on Ubuntu and phone the are synchronized to the second. I have tried this on multiple computers. Google authenticator works with all 9 other 2fa logins I use it for. I have tried many times and asked AI what I'm doing wrong Grok said I am not doing anything wrong after walking through the entire process. I have tried clearing cache and deleting cookies, signing out and back in without success. Please help I use firefox as my password manager and love it but want it to be as secure as possible. thank you very much. Thomas
