There is still a major annoyance with Google Authenticator etc.:
When you switch your device, you have to set up your 2FA credentials again …
- jjnoakes 10y agoI store the original 2fa seed somewhere offline and safe (wallet, safe, etc) so that I can bootstrap a new auth device at will.
- Yhippa 10y agoThis is why I now use SMS authentication.
- chmars 10y agoI do sometimes too … although it is less secure … and if you are abroad, it can be expensive due to roaming charges … or you are not online at all …
- scrollaway 10y agoNot only do you get the same issue with SMS authentication (have to set it up again when you get a new number), but on top of it SMS auth is not as readily available and has proprietary requirements (namely, you have to have a mobile number with text support, it has to be available at your current location, it may cost money, the auth service has to support whichever country code you're under, ...). Also, as other people mentioned, it's technically possible to back up your initial seed. SMS auth is a disgrace, when we have 2fa standards.
- eddyg 10y agoThis is not a problem with 1Password, which syncs TOTP keys as part of your secure keychain, making it easy to use multiple devices, or even just your desktop.
- marklyon 10y agoAuthy solves this problem and lets you share among devices.
