Authentication
Authentication is the process of verifying that a user or system is who they claim to be, like logging into an app with a password or fingerprint.
How it works
It works by checking provided credentials (e.g., passwords, biometrics, security tokens) against a stored record. This is a fundamental security measure that protects data and systems by ensuring only authorized individuals can access them.
Examples
- 1.Entering a username and password to access your email account
- 2.Using your phone's fingerprint scanner to unlock a banking app
- 3.A website sending a one-time code to your phone for a second verification step
