Tag: Authentication

Authentication is like a digital secret handshake. It’s the process of verifying that someone (or something) is who they claim to be. Think of it as proving your identity when you log into a computer, a website, or an app. There are several methods:

1. Passwords and PINs: The classic. You type in a secret code only you know.
2. Biometrics: Using your unique physical traits, like fingerprints, facial recognition, or even voice.
3. Two-Factor Authentication (2FA): This adds an extra layer of security by requiring a second form of verification, like a code sent to your phone.
4. Smart Cards and Tokens: These are physical devices that generate or store authentication credentials.

Why is it important? To keep your data and accounts secure from unauthorized access. It’s all about making sure that if someone is accessing your information, it’s really you!
