What are authentication tokens?

Authentication tokens, also known as security tokens or tokens, are small physical devices or software applications used to provide an additional layer of security to the authentication process. They are often used in multi-factor authentication systems, where more than one factor is required to verify the identity of a user.

Authentication tokens typically generate a one-time password (OTP) that is used in conjunction with a username and password to authenticate the user. The OTP is usually valid for a short period of time and can only be used once, making it more difficult for attackers to steal or guess the user's credentials.

There are different types of authentication tokens, including hardware tokens, such as smart cards, USB tokens, and key fobs, and software tokens, such as mobile apps or browser extensions. Some authentication tokens may also include biometric features, such as fingerprint scanners or facial recognition technology, for added security.

Authentication tokens can be used in various settings, including online banking, remote access to corporate networks, and other secure systems that require high levels of security. While authentication tokens provide an additional layer of security, they also require proper management and maintenance to ensure they are secure and effective in protecting against unauthorized access.
