I'm trying to turn on two-factor authentication (2FA) on a Google Account, but I'm in the stalemate to try to turn it on.
I'm using an updated Firefox browser.
When I try to activate 2FA, Google offers me three options:
- SMS code
- Security key
- Google's invitation
I am not looking for SMS codes (considered obsolete as a security measure) or Google's prompt; I would like a complete 2FA solution.
The security key is an option, but apparently I can not use it because Google does not offer WebAuthn (supported by my browsers), but offers the old FIDO U2F standard. The option to activate a security key simply fails silently.
This leaves no option in this list, but to my knowledge, Google also supports TOTP authentication. To enable this feature, Google documents a process in which I go into the settings of their GMail application on an Android or IOS smartphone, but I have neither. I have a device that supports TOTP authentication: I just need the secret key or QR code.
How do I get this TOTP key and activate TOTP 2FA in my Google Account?
