Local admin management

New Contributor III

Is there a tool to manage local admin accounts similar to a LAPS tool that doesn't depend on Active Directory to manage the password?

I checked out the tool at the following link, which looked promising, but it appears dependent on AD to manage the password:


Is there a tool like this that operates independently of an AD environment?

Yes, take a look at LAPSforMac.

@mark.mahabir Thanks! I have one concern with this option:

"As currently designed, this solution creates a local Admin account on every Mac enrolled into Casper and stores the account password in the Mac's inventory record as an Extension Attribute. "

It doesn't say it right out, but does it store that password in plaintext?

@asher.wilkinson Yep, it's in plaintext like any extension attribute. My org uses the same LAPS solution, and we just make use of the built-in Jamf user permissions to limit access to viewing or editing that field. Not everyone needs to have full admin access.

@sshort Thanks! That might work.

@sshort Nevermind. I just got a swift, hard no on that. Plaintext being a considerable security vulnerability, I guess it makes sense.

@asher.wilkinson I've actually just finished creating somehting like this.

It might not be exactly what you're looking for, as I doubt we're using the same password management tool, though hopefully it will spark a few bright ideas.

In our case we're using Password State as our password management tool, which has it's own API. You should be able to adapt this for use with another password management tool if it has it's own API (annoyingly not all of them do).
Our supporters then have access to Password State in case they need to retreive the local admin password.

I've added some comments into the script rather than trying to explain how it all works the description.

Seeing as we're doing this in the name of security, you could also look at going one step further and using encrypted strings for the old admin password and the API key within the script.



# This script will generate a random base64 string using OpenSSL.
# The string is then used as the new password for the Mac.
# New password is set using sysadminctl and the password
# is sent to Password State via the Password State API.

@tfenna Thanks a lot! And sorry for the late response. At a glance, this looks exactly like what I'm looking for! I'll see what I can do with it. Thank you so much!

You may also test EasyLAPS. I'm the author of this tool which is designed to regularly rotate the local administrator account password of a Mac and store it in a MDM like Jamf Pro or Jamf School.
