- Smart card authentication: Beyond traditional SSO, there is also hardware that can facilitate the same process, such as physical smart card devices that users plug into their computer. Software on the computer interacts with cryptographic keys on the smart card to authenticate the user. While the smart cards are highly secure and require a PIN to be operated, they have to be physically carried by the user—running the risk of being lost—and they can be expensive to operate.
