“Passkeys,” the secure authentication mechanism built to replace passwords, are getting more portable and easier for organizations to implement thanks to new initiatives the FIDO Alliance announced on Monday.
Usually just an option in addition to a password + MFA. Or they just replace the MFA option and still require a password. I even saw some variants where it replaced the password but still required a MFA code. It’s all over the place. Some providers artificially limit passkeys to certain (usually mobile) platforms.
All of those options are to NIST-spec. MFA means multi-factor. It doesnt matter what they are as long as they are in different categories (something you know, something you have, something you are, etc: password, passkey, auth token, auth app, physical location, the network you are connected to). Two or more of these and you are set (though, location might be a weak factor).
