Syncing of "MFA codes" is really syncing of the secret component of TOTP (time based one time password).
And it's a good thing, and damn any 2fa solution that blocks it. I don't want to go through onerous, incompetent, poorly designed account recovery procedures if a toddler smashes my phone. So I use authy personally, while a friend backs his up locally.
- skybrian 3y agoA better way to fix this is to have multiple ways to log in. Printed backup codes in your safe with your personal papers and/or a Yubikey on your keychain. This works for Google and Github, at least. Passkey syncing is more convenient, though, and probably an improvement on what most people do.
- itake 3y ago> I don't want to go through onerous, incompetent, poorly designed account recovery procedures if a toddler smashes my phone Why don't you use the printed recovery tokens?
- monocasa 3y agoWho has a printer these days?
- CameronNemo 3y agoLocal libraries, print shops... but yeah that may be an attack vector.
- unethical_ban 3y agoNot all websites offer them. Hell, no bank I use (several large and several regional) support generic totp. Some have sms, one has Symantec VIP, proprietary and not redundant. Edit: since I'm posting too fast according to HN, even though I haven't posted in an hour, I'll say it here. Symantec is totp but You cannot back up your secrets and you cannot have backup codes.
- CameronNemo 3y agoSymantec VIP is TOTP under the hood. https://github.com/dlenski/python-vipaccess https://github.com/dlenski/python-vipaccess

- e12e 3y ago> Why don't you use the printed recovery tokens? I currently see 53 2fa tokens in my private bitwarden. You expect me to print, keep safe and manually reset them all when I buy a new phone?
- charcircuit 3y agoIf you can backup a key it is not MFA. It just a second password and not another factor. The solution to having your phone smashed is to have multiple "something you have", so you have a backup.
