in by putting your pass code. this is obviously insecure. because all the other person needs code or the password and they are in. the passkey acts a little bit like a keycard, it checks who i am as well as if i have the right code. but with pass keys, it is all done on a device and a clever encryption. setting up a passkey takes a few minutes to make the online service asks you to identify your identity from the device it's not hard, but it is more of a hassle to set up than a password. wise�*s huge shift taking place and is it worth it? well, passwords have always been a terrible way to keep us safe. how bad our passwords as a security measure? awful. i would say if a company is restricting things only bypass what your 100% vulnerable.
