All of my other apps automatically back themselves up, or Apple/Google backs things up for me. When I get a new phone or wipe my phone... after logging into all my account I fully expect my Authenticator app to show up on my home screen and have all my codes in there exactly as I left it before.
This is a huge pitfall for the unaware... you will lose all of your codes, and potentially access to whatever services or things they were protecting.
TOTP is not tied to any app. When you set it up, save the TOTP seed in a secure place that you control. There is no need to rely on any app, which would be too fragile to consider.
I consider Google Authenticator to be unacceptably bad.
We all agree SMS 2FA is not as secure as we'd like it to be... but no alternative exists. It's the classic sliding scale between usability and security. The most secure system is one you cannot use... and the most usable system is one with no security. We need something that is very usable, and still secure... perhaps a tall ask but that is indeed what we're after.
Until then... regular people will continue to use SMS for 2FA. We should be happy people are at least comfortable with SMS 2FA instead of not using 2FA at all.
I don't think that's a huge problem.
> No, it's tied to the app because the initial secret is destroyed after you set it up. Every single Authenticator App I've used (which is not all of them admittedly), requires manual backups - typically in some printed form.
i scan the QR codes with a normal code reader, and then put the information into keepassxc. i can view the secret, generate codes, do whatever, and it's all with decent open source stuff and stored in a file i can back up.
