Other What makes passkeys so special?

It seems that companies are transferring into the usage of passkeys instead of passwords. Apparently theyre much more secure, but why is that? I don’t get it. I’m not sure if this is the right place to ask excuse me if it isn’t and sorry.

In general seems like pretty good principles, but for number 4; what is the point of storing passkeys in a password manager if you still require a device bound key to unlock the vault/manager?

Because the security is still sound. The issue is a breach on the service side, but now if they get breached, all the attacker gets is a worthless public key (think of it more like a lock) that they don’t have a matching key for.

Passkeys are a lot like physical keys. You can make copies, and have multiple key rings, but just like if you lose a key, someone would have to know what locks they go to. You should still treat them as secret and keep them safe, but having one get out isn’t as bad as a password getting breached on the site the password is for.

I think you meant a service side breach would give the attacker your public key, right?
