Online Security Ko Banaye Majboot 2FA Kaise Kare Kaam
2FA Kya Hota Hai?
Two-Factor Authentication (2FA) ek extra security layer hota hai jo aapke account ko unauthorized access se bachata hai. Jab aap apne account ka password dalte hain, uske baad ek aur step ki zaroorat hoti hai jisme aapko apni identity confirm karni hoti hai.
Example:
- Aapne apne email ka password dala.
- Uske baad ek OTP (One-Time Password) aapke registered mobile pe aaya.
- Jab tak aap OTP nahi dalte, tab tak aap apne account ko access nahi kar sakte.
Yeh extra step hacker ke liye account ko todna mushkil bana deta hai.
2FA Kaise Kaam Karta Hai?
2FA ka kaam simple hai. Jab aap apne account me login karte hain, tab aapko apni identity confirm karni hoti hai. Iske liye do steps ka istemal hota hai:
1. Pehla Step – Password or PIN
- Pehle step me aap apna password ya PIN dalte hain.
- Ye basic security layer hoti hai jo aap apne account ke liye set karte hain.
2. Dusra Step – Verification Code Ya Physical Confirmation
- Dusre step me aapko ek verification code milta hai jo aapke mobile number, email, ya authentication app pe aata hai.
- Kabhi-kabhi ye physical confirmation bhi ho sakta hai jaise fingerprint scan, face recognition, ya security key.
Jab tak dono steps complete nahi hote, tab tak account access nahi hota.
2FA Kyu Zaroori Hai?
Online security ke liye sirf strong password kaafi nahi hota. Hackers naye tarike dhoondte rehte hain jinke through wo aapka password chura sakte hain. 2FA ki zaroorat isliye padti hai kyunki yeh ek extra security layer deti hai.
1. Password Chori Hone Par Bhi Safe
Agar kisi tarah se aapka password leak ho jaye, tab bhi hacker aapka account access nahi kar sakta jab tak uske paas verification code na ho.
2. Phishing Attacks Se Suraksha
Phishing ke through hackers aapse password le sakte hain, lekin bina 2FA ke wo aapke account tak nahi pahuch sakte.
3. Multiple Security Layers
2FA ek extra step add karta hai jo aapki security ko double kar deta hai. Hacker ko dono steps ko todna mushkil hota hai.
4. Online Transactions Ko Safe Banata Hai
Online banking, shopping, ya money transfer ke samay 2FA aapko extra protection deta hai.

2. Email-Based 2FA
