Resetting the Admin Password
Last modified on 09 August 2020 06:00 PM

PaperCut has a built in administrator account (called “admin”) that is available even if a connection to the domain / directory cannot be established. The default username for this account is admin, and the password is set during the setup wizard when the system was first installed. This account is not related to the domain administrator account.

To change/reset the password manually (not via the web interface), firstly shutdown the Application Server service then:

Mac: Ensure you are logged in with an administrator account and browse to /Applications/PaperCut [NG/MF]/server/ then right click the file and select open with TextEdit. Then change the admin.password entry as shown below.

Windows: Open the following file in a text editor: [app_dir]/server/ and modify the line admin.password=. If the password has been set by the system it will be prefixed with HASH: - remove this when manually entering a plain text password.

For example, change:


To something like this:


This allows you to set a password in cleartext. Save and close the file, then start the Application Server service back up again. Wait a minute or two, and when you log back into the admin interface, go to Options -> Advanced -> Reset admin password to change the password back to the hashed (i.e. encrypted) format.

Tip: If you’re running on Windows, and the file is locked, you may need to run Notepad with Administrator privileges - Find ‘notepad’ in your Start menu, then right-click and select ‘Run as Administrator’. When notepad opens, use the ‘File → Open’ menus from that instance of notepad to open and edit the file above.

Using SSO and having problems?

If you’re using PaperCut’s SSO functionality you may want to login manually rather than use SSO. To do this, simply change the url from http://servername:9191/admin to http://servername:9191/admin/nosso

Mobility Print (with NG/MF)

The Mobility Print admin interface will let you log in with any PaperCut NG/MF account that is either:

  • A built in admin account (e.g. ‘admin’ account) in PaperCut NG/MF
  • A user account configured in PaperCut NG/MF with the “Access Options Section” admin right configured.

You can manage the usernames that have access, through PaperCut NG/MF. To reset the password for those accounts managed by PaperCut NG/MF:

  • For the built in ‘admin’ account, follow the PaperCut NG/MF instructions above.
  • For internal users in PaperCut NG/MF, follow the Resetting Internal User Password instructions
  • For regular domain / user directory accounts in PaperCut NG/MF, you’ll need to reset the password in your user directory system - for example Active Directory or LDAP manager.
