Two-Factor Authentication (2FA) Kya Hai?
Two-Factor Authentication (2FA) ek security system hai jo aapke login ko do alag alag cheezein verify karke secure karta hai:
-
Pehla factor: Aapka password ya PIN
-
Dusra factor: Ek extra code ya device confirmation (jaise OTP, fingerprint, ya app notification)
Iska matlab hai, agar kisi ne aapka password jaan bhi liya, toh wo bina doosri verification ke login nahi kar sakta.
2FA Kaise Kaam Karta Hai?
Jab aap apne account mein login karte hain:
✅ Pehle aap username aur password enter karte hain.
✅ Phir system aapse ek extra proof maangta hai — jaise phone par aaya ek OTP ya fingerprint scan.
Agar dono steps complete hote hain, tabhi aapka account unlock hota hai.
