# Granting Topic Access Permissions to Users

To see how permissions affect the ability to publish and receive messages, grant publish permission to `user1` and subscribe permission to the `user2`.

Use the grant topic command to grant permissions to users on the topic `myTopic`.

In the administration tool, enter:

       tcp://localhost:7222> grant topic myTopic user1 publish
       tcp://localhost:7222> grant topic myTopic user2 subscribe

For more information on the `grant topic` command, refer to `grant topic`.
