No-IP has a sub account feature that can be used to limit the access an update client has to your account. You may want to do this if you are ever in a scenario where you are installing an update client at multiple locations and you might not be the sole user of that computer or device. We’ve had many support requests from a frantic IT provider who accidentally updated all his customer locations to his home IP address. Using a separate sub account and limiting it to just the hostname for the given location will prevent this.
You can create a sub-account by using the password feature in the update groups.
To create a sub-account go to “Manage Groups“ under the “Hosts / Redirects” section on the site. Click on “Add A Group“ to create a new group and name it, (in our example “100Washington”).
Click on next, you will then be prompted to add one or more hosts to your group. After adding the hosts that you want this sub-account to have access to, click “Confirm Changes”. Go back to the “Manage Groups“ section.
Click on “Set Password“.
Read the instructions and set your password.
You have just set-up your sub or group account. To update this group with your dynamic update client you will just have to provide the following login information:
Username = groupname:username [email address or username will work]
Password = the group password you just configured
Note: Some clients don’t like a colon(:) character as a separator, you can use the url encoded colon character %3A %23 or # if you run into this issue.
