Change User Access to stop unlocking period.

Hi CarolineG 

The Preferences window can be set up to have Read & Write access, Read Only access or No access for users. It is in how you set up the function of that role.

If you are needing to review a role and their access to that Preferences window do complete the following process:

1. Log into the company file as an Administrator user
2. Navigate to Setup>>User Access 
3. Select Manage Roles
4. Highlight the desired role (left-hand side)
5. Select General
   • If the Preferences option is not ticked, users with that role wouldn't have access to the Preferences window
   • If the Preference option was ticked and Read only enabled they would have read-only access
   • If the Preference option was ticked and Read & Write enabled they would have full access
6. When reviewed, select Save

Using the above process you can edit the access to the Preference window for a user role.

Help Article: Set up roles has more information on user roles and how you can edit the role to restrict access to functions and features.
