Two-factor authentication ka matlab hai ke account kholne ke liye do cheezein darkar hon: ek jo aap jante hain (password) aur ek jo aapke paas hai (phone ya app).
Faida ye hai ke agar kisi ko aapka password mil bhi jaye, wo phir bhi andar nahi aa sakta, kyunke doosri cheez uske paas nahi hoti. Aaj kal password ke leak hone ke waqiat aam hain, is liye ye ek parat ka farq bara hota hai.
Do aam tareeqe hain. Pehla SMS par code aana. Doosra authenticator app, jo har tees second baad naya code banati hai. App wala tareeqa zyada mehfooz samjha jata hai, kyunke SIM ka dhoke se badal liya jana — jise SIM swap kaha jata hai — SMS wale tareeqe ko toor sakta hai.
Setup ke waqt milne wale backup code kahin mehfooz jagah likh lein. Phone gum hone ki soorat mein yahi account wapas dilate hain.
Kahan sab se pehle on karein
- Email — kyunke baaqi sab ka password isi se reset hota hai
- Bank aur mobile wallet
- Social media accounts
- Wo jagah jahan aapka karobar chalta ho
