Replacing or removing firmware password

[Hippocrates]

I own a 2012 Macbook Pro with retina display. I'm trying to follow the recommendation of Undercover, an anti-theft software by setting a firmware password.

I'm hesitating because there's no documentation on whether it's possible to replace the old password with a new one (knowing my own password!), or just to remove it and reverting the system back to a "no-password" state in the future. Can anyone with experience in setting firmware password help? Thanks a lot.

You set it from the recovery partition. Just command-r boot and you will see the screen like in this article. The firmware password utility is under the Utilities menu.

You can just run the utility again and change the PW, or run it again and leave it blank to remove the password.

Thanks a lot. Being able to leave it blank to remove a pre-existing password is all I hope to know
