p4 login
Synopsis
Log in to a Perforce server by obtaining a ticket.
Syntax
p4 [g-opts] login [ -a -p ] [ user ]
p4 [g-opts] login [ -s ]
Description
The p4 login command authenticates a user and creates a ticket that represents a session with a Perforce server. Once authenticated, a user may access the Perforce server until either the ticket expires or until the user issues the p4 logout command.
By default, tickets are valid for 12 hours.
To obtain a ticket valid for all IP addresses (for instance, to use Perforce simultaneously on more than one machine), use p4 login -a. Users with tickets that are valid for all IP addresses still consume only one Perforce license.

- The default timeout value of 43200 seconds (12 hours) is defined on a per-group basis in the p4 group form.
- To create tickets that do not expire, set the timeout value to unlimited in the p4 group form.
- To extend a ticket's lifespan, use p4 login while already logged in. Your ticket's lifespan is extended by 1/3 of its initial timeout setting, subject to a maximum of your ticket's initial timeout setting.
- Perforce superusers may obtain login tickets for users other than themselves without entering passwords. Non-superusers may obtain tickets for other users if and only if they correctly supply the other user's password.
- Tickets are stored in the file specified by the P4TICKETS environment variable. If this variable is not set, tickets are stored in %USERPROFILE%\p4tickets.txt on Windows, and in $HOME/.p4tickets on other operating systems.
