Basics of securing your account
Protecting your account is important. With access to your account you can change all settings on your domain name and have full access to the DNS. Making sure that only the right people can access it and make changes is vital.
Naturally we recommend choosing a strong password. Don't focus too much on special characters and such, the most important thing is to make it hard to guess and not too short. The password 'openprovideruser' too easy to guess, choosing something like 'whatdoyougetifyoumultiplysixbynine42' is a lot more secure and still easy to remember.
One of the strongest forms of protection from outsiders accessing your account is limiting which IP addresses are allowed to log on.
You have the choice to limit a specific user to log on via the RCP (Reseller Control Panel) or the API (System Automation) from specific IP addresses, or block access from specific addresses.
Configuring a white-/blacklist entry
To configure an user to use the white-/blacklisting functionality, you will first need to find the contact you want to limit in the control panel. The list of the active users in your account can be found by navigating to Account -> Account Overview -> Contact Persons. Or, simply go there directly by clicking here!
On this page, select the user you want to edit and click 'Modify' on the next page that loads. Now scroll down to the end of the page and you will see two blocks for the RCP and API white-/blacklisting.
In these example screenshots I have allowed access to both API and RCP only from the IP 18.104.22.168. At the same time I have disallowed access from 22.214.171.124.
Remember. If you add someone to the whitelist, only people attempting to log on from that specific IP will be granted access. All logon attempts from different sources will be declined. If you only add an IP in the blacklist, only that single IP is prevented from logging on, other IPs can still access your account if they have the right credentials.
In all lists, the use of wildcards is allowed. For example, white listing IP address 93.180.69.* allows any connection from IP addresses 126.96.36.199 to 188.8.131.52. IPv6 is supported as well.
