Hardware tokens, often referred to as security tokens or authentication tokens, are physical devices used to generate or store authentication credentials. They serve as a second factor in multi-factor authentication (MFA), significantly enhancing security by requiring something the user possesses in addition to something they know (like a password) or something they are (like a fingerprint).

There are several types of hardware tokens. One common type is the one-time password (OTP) generator, which displays a constantly changing code that is valid for a short period. Another type is the smart card, which contains a microchip that stores cryptographic keys and can perform secure operations. USB tokens, often called "security keys," plug into a computer's USB port and can authenticate users through cryptographic protocols like FIDO U2F or FIDO2.

Hardware tokens are widely used in enterprise environments and by individuals seeking robust security for sensitive accounts. Their physical nature makes them resistant to phishing attacks, as the token's output cannot be easily intercepted remotely. Lost or stolen tokens can typically be deactivated remotely, and compromised tokens do not grant access without the other factors of authentication. The management of hardware tokens involves issuing, provisioning, and deactivating devices, which is an important aspect of their implementation in security systems.
