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 “DNS Records“ under the “My Services” section on the site. Click on “Manage Groups”. To create a new group, click “Add A Group” and name it, (in our example “Group1″).
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.
