But my question is what was that OTP for? And where can I get this OTP? What does it do?
You have made a good point and asked about OTP in the right thread for a solution. OTP is a system code that allows us to log in to our accounts securely. Using this, we log accounts securely. OTP stands for
Short-Time Password and is usually used to confirm the correct identity of the user. OTP system is used to secure the account. The OTP is generally sent via SMS, e-mail, or a particular OTP generator application. Account users confirm their identity by entering the OTP received within the specified period and using their account securely.
How OTP can stand for "Short-Time Password" while the first letter doesn't match with the first letter of the first word "short"? Actually it stands for One-Time Password. Because the password is only valid one single time.
