You can invite a fellow Canny admin by going to the Admins page in your Canny settings:

At the top of the page, you can send invites via email. Enter one or more addresses and send the invite(s). Your teammates just need to accept the email invite to join Canny as an admin!

Don't forget to select their admin role! (Available on the Growth and Business plans)

A detailed explanation of admin roles is available here:

That's it! Let us know if you have any problems.
