p4 passwd

Synopsis

Syntax

Description

Once you have set a password, it must be provided to the Perforce server program when any Perforce client 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 Perforce client command line, as in p4 -u ida -P idaspwd edit .

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

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

Options

-O oldpassword	Avoid prompting by specifying the old password on the command line.
-P newpassword	Avoid prompting by specifying the new password on the command line.
user	Superusers can provide this argument to change the password of another user.
g-opts	See the Global Options section.

• 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 such passwords requires quotes. For instance, to pass the password my passw, to Perforce, use p4 -P "my passw" command .

• If a user forgets his or her password, a Perforce superuser can reset it by specifying the username on the command line: p4 passwd username

• The maximum password length is 1024 characters on all platforms.
