The difference is, you literally never give the private key to anyone. Nobody will ever ask for it.
It works through public private key encryption. To login the site will send your computer a “challenge” (some kind of math problem) that’s first encrypted with your public key. That means only your private key will be able to decrypt the challenge. Then your machine will generate an answer, encrypt it with the private key and sent that back. If the public key decrypts the answer and it matches, they know you are you.
Except they don’t. They may request a passkey which is just an oversimplification about what is going on behind the scenes, with information being passed back and forth as Steve described.
But the private key never leaves the device. This is such a huge distinction that is easy to overlook. But it is very, very important.
Haha fair enough. I should have known from the quotes. It is something I hear a lot from people who don’t know the difference, and I’m sure you do too.
not exacly, if someone hack a site that has poor security they gonna have your password, it you put your passkey there, it’s useless, also people can’t see you writibg yoyr password if don’t write it
Yes, but a password is a shared secret. So both you and the person you are interacting with need the password and therefore it is more vulnerable. With a past key, only you have the private key and the company or service you are interacting with never has access to the secret. Basically, they encrypt a message to you using your public key and then your private key decrypts it and sends them a response back with the correct answer.

I guess my sarcasm needed the /s; was just mocking people who would try to retort with some half brained comment like that.
Of course passkeys are better and more secure, I’m 100% on board with them.

But if you’re using it now, wouldn’t it be a present key?
Lol. Nice
