Access Simulator helps you pre-validate how access to a specified table would change after a role or group is assigned or removed from the user.

Use Access Simulator to simulate access requirements of your users on a specified table and understand how the access controls change for a user. It helps in quickly troubleshooting and validating the effectiveness of changes.

Use Access Simulator to pre-validate access for a selected user by:

* [Add roles to users](https://www.servicenow.com/docs/3bBJqhJxIm6trOJPmN~m3Q "Use the Simulate Add Role for simulating the user's access changes for a resource (table).")
* [Remove roles from users](https://www.servicenow.com/docs/Az6xJMWqHSW4kvKutAp4OQ "Use the Simulate Remove Role for simulating the user's access changes for a resource (tables).")
* [Add users to groups](https://www.servicenow.com/docs/wguIZat8QTE92Hixz8h4gA "Use the Simulate Add to Group for simulating the user's access changes for a resource (table).")
* [Remove users from groups](https://www.servicenow.com/docs/V2_Rajt7L~wSaJptyjFUjg "Use the Simulate Remove from Group for simulating the user's access changes for a resource (table).")
