What is an OTP?
An OTP, or One-Time Password, is a password that is valid for only one login session or transaction. It's a common form of two-factor authentication (2FA) used to enhance security. By requiring a code that is constantly changing, OTPs make it much more difficult for unauthorized users to gain access to an account, even if they have stolen the primary password.
