Authentication is the process of verifying the identity of a user or system. It ensures that only authorized individuals or systems can access sensitive information or perform certain actions.
Common Authentication Methods
- Username and Password: The most common method, where users provide a username and a password to gain access.
- Two-Factor Authentication (2FA): Adds an additional layer of security by requiring something the user knows (password) and something the user has (a mobile device).
- Biometric Authentication: Uses unique physical characteristics like fingerprints, facial recognition, or iris scans to verify identity.
Tips for Strong Authentication
- Use strong, unique passwords.
- Enable 2FA whenever possible.
- Keep your software and devices updated.
