Entity Authentication, Biometric Passwords ,and Challenge Response Protocol
Ever tried logging in where you had to prove you're really you? That’s entity authentication — it checks your identity before letting you in.
Now, instead of typing passwords, imagine just using your fingerprint or face — that’s a biometric password .
And sometimes, the system might throw a quick question your way and wait for the right answer — that’s called a challenge-response protocol. All these work together to keep your accounts safe and locked from strangers!
