You didn't read any of those screens warning about you needing the backup codes? I do realize some services don't provide backup codes (which is insane), but when they don't I have found that they provide the codes you can manually type in to authenticator apps. With that, you can add the code in multiple places, like on your phone and also another computer with any totp app like authy or TOFU or whatever to have a 'backup'. I keep my backup codes in a plain text files in a folder on my home NAS which is encrypted on disk, and backs up through rclone (with encryption) to backblaze every night. I'm about to configure up a second NAS for redundancy because 3 2 1.
