A new login technique is becoming available in 2023: the passkey. The passkey promises to solve phishing and prevent password reuse. But lots of smart and security-oriented folks are confused about what exactly a passkey is. There’s a good reason for that. A passkey is in some sense one of two (or three) different things, depending on how it’s stored.
FYI Yubico (who makes them) have devices compatible with each. You can technically use the passkey standard with a yubikey security key since it’s all FIDO2 protocols, but it’s certainly not standard
It’s just a question of device bound keys (the default for yubikeys) vs platform / exportable keys (passkeys), but the websites can’t tell the difference if you don’t tell it

Yubikey ftw
That’s not a passkey. It’s a security key. RTA.

Which I would lose in a time period so short it is not yet measurable by science.
Think we have five of them taped to the wall at work.
Glassless breakglass :)
Hopefully you don’t open the door to your house with a key lol
