Authentication method | Description | Advantages & disadvantages |
---|
Zero login & biometrics | Allows a user to login without using a username & password Uses biometric data (fingerprint, face, gestures) to create a profile of a user so that they can log in without having to authenticate each time
| Convenient for devices when users need to log in frequently throughout the day e.g. smartphones If compromised, biometric data cannot be changed Biometric recognition can be less than perfect and lead to failed login attempts and user frustration
|
Magnetic stripe | Magnetic stripe contains unique data used to authenticate a user e.g. ID, name & date of birth When swiped through a magnetic card reader, details are used to identify a user
| Easy and cheap to setup Cards can be used to access multiple systems Cards can be remotely deactivated Magnetic stripes can wear Card readers must be maintained Less secure than biometrics (easy copied)
|
Smart cards | | More secure than magnetic stripe cards Multi-purpose Transactions can be much faster More expensive to manufacture Lack of compatibility can cause inconvenience
|
Physical tokens | A physical device used to authenticate a user remotely The device generates a random one time password (OTP) that a user must type in Banks may ask customers to insert their bank card into the device and use the OTP to access internet banking OTPs change after a few minutes

Electronic tokens | | Very secure More convenient
