Today suddenly after my id logout, while logging in I see that there is a blank field named OTP where I have to give my OTP, but I don't know what my OTP is. Then without understanding anything I login with username and password without OTP and my ID is logged in.
But my question is what was that OTP for? And where can I get this OTP? What does it do?
If you don't on this option in your account then turn on it asap. And As I see you don't know anything about OTP so you also don't know how to on it.
