locked if your Mac

You can display a keychain lock icon in the menu bar and use it to quickly lock or unlock your keychain. In Keychain Access, choose Keychain Access > Preferences. Click General, then click Show Status in Menu Bar.

Problem when I reboot mac lock icon in the menu bar will be gone automatically

I'm Using Ad account on my Mac

Thanks Senthil Kumar

I have a Self Service policy users can run and the lock icon stays there always. The policy only consists of Files and Processes > Execute Command

open /Applications/Utilities/Keychain Access.app/Contents/Resources/Keychain.menu

Users run that and the icon stays.

Thanks, it is working via self-service policy
