What is meant by User Authentication?
User authentication is a security process where the identity of a user is verified to ensure that they are indeed who they claim to be. This process typically involves entering credentials such as a username and password, although other methods such as biometric data, security tokens, or two-factor authentication can also be used. User authentication is an essential component of access control and helps prevent unauthorized access to sensitive data or systems.
Typical functions of software in the field of "user authentication" include:
- User login: Providing a login process where users can enter their credentials to authenticate themselves to the system.
- Verification of credentials: Verifying the entered credentials such as username and password to ensure they are correct and match an authorized user account.
- Multi-factor authentication: Supporting multi-factor authentication methods such as two-factor authentication (2FA) or biometric authentication to enhance security.
- Password policies: Setting password policies such as minimum length, complexity requirements, and expiration dates to improve the security of credentials.
- User registration and management: Managing user accounts, including registering new users, updating profile information, and deactivating or deleting user accounts.
- Logging and monitoring: Logging login events and monitoring login activities to detect suspicious or unusual activities.
- Security enhancements: Implementing additional security measures such as Captcha, IP whitelisting, or anti-phishing mechanisms to protect users from fraudulent activities.
