p4 passwd

Synopsis

Change a user's Perforce password on the server.

Syntax

Description

By default, user records are created without passwords, and any Perforce user can impersonate another by setting P4USER or by using the globally-available -u flag. To prevent another user from impersonating you, use p4 passwd to set your password to any string that doesn't contain whitespace or the comment character #.

Once a password has been set, it must be provided to the p4d server program when any p4 command is run. You can do this in one of three ways:

• Set the environment or registry variable P4PASSWD to the password value;
• Create a setting for P4PASSWD within the P4CONFIG file;
• Use the -P password flag on the p4 command line, as in p4 -u ida -P idaspwd edit .

Each of these three methods overrides the methods above it.

On Windows clients, p4 passwd stores the password for you by performing p4 set to change the local registry variable. (Note that the registry variable holds only the encrypted MD5 hash of the password, not the password itself.)

To delete a password, set the password value to an empty string.

Options

Usage Notes

• The p4 passwd command never sends plaintext passwords over the network; a challenge/response mechanism is used to send the MD5 hash of the password to the server.
• Passwords may contain spaces; command line use of this password requires quotes. Thus, if a user's password is my password, it would be provided in a Perforce command as p4 -P "my password" command .
