Password protection definition
Password protection is an access control mechanism that prevents unauthorized access to computer systems and data by validating user identity through authentication. Only authorized users with the proper credentials, such as usernames and passwords, can access the online data. Some organizations implement password protection policies that prevent people from using weak passwords and commonly used variations, as well as employ specialized software for password protection to keep sensitive data safe. The password protection mechanism is a substantial security measure against different hacking methods.
