That is but one method of Yubikey. They also support cryptographic passkeys and can store TOTP secrets as well as PGP crypto keys.

The “touch key random key” is a OTP code that can be used for legacy software, Passkey and/or other functions are more valuable to me. Can read more about OTP security here.

Yeah, unsalted MD5 has been crackable easily for at least 20 years now. 🤣

I would not trust it as a single factor, but 2FA should always be something you have+something you know, biometeics is more of a “something you ARE”, which is unchangeable.

Yubikeys are still not biometric unless you’re buying the super-super expensive one. They are just very secure MFA. (in that it’s extremely hard to read the secrets from them even with physical access)

If you push a ton of key at same time, all work?!
