Γειά σου Σταύρο If you’ve gotten locked out of your two-step authentication login, you can use one of your previously saved backup authentication codes to securely regain access to your account. Alternatively, if you have a device still signed in to your account, you can use that device to '''disable''' two-factor authentication, so you can sign in to your account without two-step authentication. When you activated it you created a recovery method for your Mozilla account. This is '''required to complete''' two-step authentication (2FA) setup. Do you have any of these? Backup authentication codes – a list of one-time use codes to save in a secure location. Recovery phone – a phone number that can receive a one-time password (OTP) via SMS if you lose access to your authenticator app. * [https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication#:~:text=I%20lost%20my%20two%2Dstep%20authentication%20device%20but%20I%20have%20another%20signed%2Din%20device,-If I lost my two-step authentication device but I have another signed-in device] * [https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication#:~:text=I%20lost%20my%20two%2Dstep%20authentication%20device%20but%20I%20have%20a%20backup%20authentication%20code,-Go I lost my two-step authentication device but I have a backup authentication code] * [https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication#:~:text=I%20lost%20my%20two%2Dstep%20authentication%20device%20but%20I%20have%20a%20recovery%20phone,-After I lost my two-step authentication device but I have a recovery phone] More info [[What if I'm locked out of Two-Step Authentication?]]

Thank you for your prompt reply and guidance on this George. Much appreciated. I am logged into my Firefox account on my Android mobile device. I will check my options there. I can access my Proton 2FA app. Issue there is that Firefox is not listed there. I can can only see othe accounts there but Firefox isn't listed anymore for some reason. I will also check if I can use my phone for OTP. If nothing works I will revert here again..Thanks. Kind Regards Stavros
