For more precise sharing you can share a specific Service with another user. All you need is the email that is associated with their remote.it account, and the Service you share will appear in their Devices tab.
To share a Service, select the Devices view, then click on the Device Name. To share a Device (all of its Services) or to choose which Service to share, click on the "Share" icon (which looks like a little person's head and shoulders) at upper right:
You will be taken to the Sharing screen for that Device. Enter one or more valid email addresses into the bar at the top. These are the user that you will be sharing the Services with.
Select the Services you want to share, or just use Select all if you wish to share all Services on the Device. You can also decide if you want to give the users the ability to run bulk scripts on the Device. When you are done configuring the permissions, click the Share button.
You can view the Shared Users on any Device that you own. Click on the Service and you will see a Users button, located at the top of the right panel.
Click on the Shared Users button and you will be brought to a screen where you can see all the users who have access to your Device, as well as what Services they have access to.
Shared shows users to whom you shared the Device or any of its Services one at a time.
Organization Members shows users to whom you shared the Device as a result of using the Organizations feature.
You can click on any user's email address to change their permissions, and you can click the Trash icon in the upper right to revoke their access. Remember to click Save to save your changes.
For sharing your entire Device List at once, refer to Organizations.
