A form of biometric authentication, fingerprint authentication automatically compares a user’s fingerprint to a stored fingerprint template in order to validate a user’s identity. Because we are all born with unique fingerprints, fingerprint scans are an inherence factor or “something you are,” making them impossible to guess and difficult to alter or fake.
Of the broad variety of authentication methods available, when fingerprint authentication is combined with a second form of authentication, such as a PIN, it provides maximum security and unparalleled user convenience.
How Fingerprint Biometrics Work With RapidIdentity MFA
RapidIdentity MFA manages the lifecycle of fingerprint biometrics by capturing three or more of a user’s fingerprint templates and a user-selected PIN during enrollment. The templates are encrypted and stored on the RapidIdentity MFA Server and synchronized with clients as needed. For privacy reasons, the user’s fingerprint image is not captured or stored; it is only a template.
To authenticate, a user presents or swipes an enrolled fingerprint on a sensor, and RapidIdentity MFA then identifies the user’s information. The user then, optionally depending on policy, enters the associated PIN or password, and this is compared to what is stored on the RapidIdentity Server. Once validated, the user is permitted access to the operating system or application.
RapidIdentity MFA provides broad support for embedded and USB connected fingerprint sensors.
Benefits of Fingerprint Biometrics
- Considered one of the most secure authentication methods
- Much harder to fake than identity cards
- Convenient and easy for the user
- Can’t be guessed, forgotten, or misplaced
- Most accepted and mature biometric authentication method
