+NetBird offers a powerful [Access Control feature](/overview/acls) that allows easy access management of your resources.
+In a basic scenario, you would create multiple groups of peers and create access rules to define what groups can access each other.
+Adding peers to groups might become time-consuming in large networks with dozens of machines.
+
+Starting NetBird [v0.9.2](https://github.com/netbirdio/netbird/releases), when creating or updating a setup key,
+it is possible to specify a list of auto-assign groups. Every peer registered with this key will be automatically added
+to these groups. All the access control rules enabled for these groups will apply automatically.
+
+To add `Auto-assign groups`, open the `Setup Keys` tab and create or update any existing setup key.
+The use this key to enroll new machine.
+
+
+ 
+
+
+:::note
+Auto-assign groups will apply only to newly registered machines.
