What is biometric authentication?

Biometric authentication can provide more security. Instead of the traditional login with user name and password, an additional factor or even a sole biometric factor is used. This includes, for example, registration via fingerprint or the well-known Face ID from Apple. 

With biometric authentication systems, data is recorded, encrypted or stored. When you log in, this data is compared and if it matches, you can log in to the system and the user gains access. Biometric technology is now also an option for two-factor authentication. For example, through facial or fingerprint recognition, a second factor can be used alongside a username and password to log in to an online service or website.

What are the benefits of biometric authentication:

• A physical factor in authentication is very secure
• A biometric factor is virtually tamper-proof

What are the benefits of biometric authentication:

• If the biometric features are not recognized (application problems), there is no possibility of registration
• Can be seen as an invasion of privacy

Well-known methods of biometric recognition are: fingerprint, voice authentication, retina scan or facial recognition.
