I've lost some of my TOTP keys because Microsoft Authenticator prevents you from exporting your keys unless you sign up. Well done VGTU students.

- SOLAR_FIELDS 3y agoMS Authenticator also at least 1 year ago did not back up your TOTP keys by default and doesn’t warn you that there’s no backup. I discovered this when I switched phones and suddenly had to reset every single one of my 2fa apps
- zvolsky 3y agoIf you think of it as a keyring there's nothing wrong with not backing up the keys by default. You are right, however, that it should inform the user about the importance of having more copies of the keys if the service doesn't implement backup codes. Personally I prefer to transfer key clones directly to backup devices without the need for the backup device to be online. The few keys that I lost due to MS Authenticator were from a time before I introduced this process.
