TOTP has horrible UX and I'm barely willing to keep using it for sites without FIDO2.
Same here
Too weak and can be phished anyway.
Correct, so can be passwords tho no matter the length.
TOTP doesn't add any significant value on top of using a password manager with random passwords.
Pretty sure that's not true. TOTP is changed every 30 seconds which makes it different from a mostly permanent password. Any 2FA would add security to an account. Well things like SMS 2FA maybe not much, but that too makes more difficult to crack an account.
FIDO2 adds lots of value and can entirely replace passwords.
True
TOTP really needs to die especially now that there are passkeys (multi-device FIDO credentials).
Agreed
Most people shouldn't ever have to learn that the horrible TOTP approach even exists. It's not good that it exists since sites are spending their time adding that instead of FIDO...
Maybe thats true but i'd say if the choice is between TOTP or no 2FA on a mainstream site, i'll take TOTP any day. If it were true that TOTP has no value beyond random passwords from a password manager Micay would not use it. But in his word he does. So there must be some value to it after all.
I'll change my original opinion regarding this forum as; there may not be a reason to add TOTP here, this project is known for the cutting edge, and best security after all, but still the argument that not everyone can afford a Yubikey or another FIDO2 certified key only recently became abundant and only because the passkey support rolling out. Still, not everyone today knows about passkeys even exist, not to mention knowing how to use them. Having your keys on a USB stick which you can bring with yourself everywhere, which is universal, and storing it on your device is still different. I'd say mainstream platforms still supporting TOTP 2FA today at least until passkeys become more popular than TOTP does no significant harm but certainly does not do as much harm as not having that option available to newbies.
But that's just my two cents in this matter.
