How to reset the Admin Password
Last updated June 4, 2026
Contents
PaperCut NG/MF has a built-in admin account. If you need to change the password or have forgotten it, use one of the following methods:
PaperCut NG/MF - change the ‘admin’ password
PaperCut has a built-in administrator account (referred to as the “internal 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.
There are two methods for changing the Admin Password:
- Method 1: Updating the password in the
server.propertiesfile on the server directly, then restarting the server. One consideration when selecting this method is that it requires a server reboot, which might take time and cause disruption to your organization. - Method 2: Updating the password in the PaperCut MF Web admin interface.
Method 1: Updating the password in the server.properties file
- Log on to the desktop of the server running PaperCut.

Method 2: Updating the password in the PaperCut NG/MF Web admin interface
- Log in to the PaperCut MF Web admin interface with the Internal Admin credentials.
- Navigate to Options > Advanced > Reset admin password.
Note: Only the official internal admin can access this page. Users with admin rights do not have access to the reset admin password setting. If you can’t see the Reset admin password option, you might not be logged in using internal admin credentials. - Click Change internal Admin Password. This message is displayed:
“For your security, click OK to log in again and change this setting.” - Click OK. You’ll be redirected to the login page to authenticate again with the internal admin credentials.
Note: This is an additional layer of security to ensure your account’s secure before making this critical change. - Enter the internal admin credentials. The page to enter the new password is displayed.
- Change the password. The updated password will be written to the
security.propertiesfile and encrypted.
