The user and group passwords in the Linux system are stored in the passwd and group files in the / etc directory, respectively.

The projection password changes the password in the file to the shadow and gshadow files in the / etc directory, which can only be read by the system administrator, while replacing the original password with the "x" character. The projection password function can be turned on or off at any time, and you only need to execute the grpconv command to turn on the group projection password.
