One-time password (OTP) systems, or one-time passwords, are an authentication method in which the user is provided with a password that is active only for one login session or transaction in an information system. Currently, the systems are not implemented in their pure form, but are one of the components in multi-factor authentication systems. Despite its widespread use in the financial sector, a one-time password does not guarantee secure login authentication.
