Or the obscure ways for 2FA/MFA. Passkeys are mostly cloud based. Yeah fuck no! The weakest Passkey is weaker than my usual random generated password, if the site don’t do any shady business and require a weak password. Hardware keys are luckily not pushed for usage. I don’t like them either. You require at least 2, for backup reasons. They also cost quite some money and they have zero auth. Just connect to usb and tap it. Also retrieving the backup and get a replacement for a defective one, takes some time.

Good old TOTP as 2FA is perfect, paired with a strong, random password. With my TOTP, I have an encrypted backup in my cloud, on my NAS, older backups in secure places and backup codes in several places. The TOTP App I use is open source and I have a mirror of the source code.

This should be enough security, if sites don’t screw up all the time. You can bypass 2FA all the time. Even the credit card company screwed up big time. Usually you get 2 separate letters, one with your pin and one with your card. Both came on the same day. Also I actually didn’t needed the pin in the first place. I was able to add the card to the app and see the pin there, without actually verifying anything, except the credit card number.

Maybe when passkeys are supported in my password manager, I will try it but so far it isn’t and switching is not an option, as it doesn’t support the features I need. There is an open issue for an alternative password manager, with that feature request and it has some people wanting it, but its still not added. But passkeys doesn’t fix the issue for me using stronger keys, it fixes the site owners to allow stronger keys but they are still not required to use it. Some devs are just weird. I’ve read one PR for an FOSS project I use, where someone wanted to implement a universal oath or such stuff, that would support all types of external authentifications. Nope, the dev refused the PR and they wanted to stay at the 2 proprietary implementations, for 2 services, even though this universal implementation would work with these 2 too. I can’t tell exactly what it was. I was experimenting with an auth service for my self hosted stuff, to not deal with several accounts and rights systems. This service was the first one which I wanted to switch and they didn’t wanted to support it, leaving me with the standard login.

Every hardware based key I ever used also required PIN, but as far as expense and backups, yes, for personal use the cost generally may not be justified. I got all my personal ones as a bundle that was on sale. For work I would argue that some businesses can easily justify the cost to create a rotating stock of hardware keys to deal with lost keys. Generally in that environment you have centralized PKI, where you can revoke the certificate on the lost key and then issue a new certificate on a new hardware key. This doesn’t help for all sign in methods tied to hardware keys, but can be very practical when implemented right.

I also agree on TOTP as the ultimate generic 2FA method, with several worsening options until the despised email or sms 2FA. I will also add that you can setup TOTP on modern hardware keys, where you must insert and complete PIN entry. The inconvenience is that you must have all your keys and password manager available at setup time for places that don’t support multiple TOTP codes.
