Provided the last person to enter config on the switch saved the config via a write mem command, then Yes you can do this.
The switch needs to be rebooted and use must be connected via the console port on the switches.

After pressing b I think you then enter the command "no password" then "boot system pri or sec".
Prerequisites: Must have physical access to the switch and console port

When the system is booted put a new password/user on the switch and also back up your config.
