You can just scan the QR code instead... The TOTP secret is contained in there, and can be copied into just about any password manager.

Please read the original post - the QR code (nor the TOTP secret in any other format) is simply not available until you enable either SMS authentication or the authentication app.

Afterwards, yes, you have the TOTP secret available for use in any tool you want - but I am repeating myself.

Google never offered a QR code like 99% of other MFAs.
