I do recommend toget 2fas.com asap and export your codes to iCloud/G Drive.

If you lose the phone its easier to recover.

Yeah, apparently that 2FA handshake is crucial with some providers. I was not expecting this, I thought careful management of my 2FA backup codes would suffice!

I would also suggest https://authy.com It has apps for phones/tablet and desktop.
