# Exploring Access Simulator

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.
