Hi,

We need another user in Vault and would like to remove the Admin user.

We have 2 other users with full admin rights. (In the Admin Group)

Is there any reason we need to keep "Admin" user? Are there any special rights it has purely because its named "Admin"?

You absolutely should never remove the admin user. It doesn't take up a license key, so removing it will not provide you with a space for an additional user. Even though other users have admin rights, there are certain actions that only the admin user can take.
