Sorry for being silly here, I’ve been kind of out of the loop with recent technology, what exactly is “passkeys”? I remember reading something when it was announcement, but all I saw was lots of buzzwords and vague “it’s new and it’s very good” claims.
Is it like, an alternative authorization method? Is it a second factor after I type my login/password, or does it replace passwords? What does it look like, from users perspective?
So pretty much same as ssh/gpg private/public keys? Do many websites support this? I don’t remember seeing any that would give me an option to register using passkeys. Also, where are the private keys stored? How do I move them from device to device (for example, I signed up on android and now want to log in on desktop)? Do I back them up and restore when I’m buying a new phone?
