Authentication is the process of verifying the identity of a user. It is important for software applications to have authentication in place to protect user accounts and data from unauthorised access.
There are many different types of authentication methods, including:
- Passwords: Passwords are the most common type of authentication method. However, they can be weak and easily compromised.
Multi-factor authentication (MFA): MFA adds an additional layer of security to authentication by requiring users to provide two or more factors of authentication. For example, a user might be required to enter a password and a code generated by an authentication app.
Biometric authentication: Biometric authentication uses physical characteristics, such as fingerprints or facial features, to authenticate users.
