# Configuring Users

Each In-Sight vision system has its own set of users, separate from every other device on the network. If a user needs access to a particular device, they must know a user name and password that already exists on that device.

When selecting a vision system on the In-Sight® Device Pane, you can use the User Configuration utility to configure users for that device. The user name and password of those users then can be used to log in to the device. This mechanism acts as a security measure, with three different access levels (Full, Protected, and Locked) available to users.

By default, every In-Sight device has one preconfigured user: admin, who has an Access Level of Full and a blank/empty password. See the Add, Modify, or Delete Users with the User Configuration Utility topic for more information on how to configure these user settings.

Note:

- Only users with an Access Level set to Full may add, delete, or modify users. However, the default admin user cannot be renamed, its Access Level cannot be modified, and it cannot be deleted either, even if another user with Full access is configured on the device.
- Each device must have a user with an Access Level set to Full.
- Each device can have a maximum of 64 users, of varying Access Levels.
- Each user name can be a maximum of 64 characters.
- User Names are case sensitive and must be unique (that is, there can be no duplicate user names on the device).
- User Names, Passwords and Comments can use Unicode characters.
- Passwords are displayed as asterisks.
- There is no minimum Password strength requirement (such as no minimum length or special characters). Passwords can also be empty or blank.
- The maximum length of a Comment is 1024 characters.
