Tamper password is a type of security measure that is used to protect systems and data from unauthorized access. It involves putting a secret code or phrase on the system that must be entered in order to gain access. This code can be changed periodically, making it difficult for hackers or other malicious actors to gain entry into the system. Tamper passwords are often used in combination with other security measures, such as biometric authentication and two-factor authentication, to ensure an extra layer of protection against malicious activity.
