DeSec.io API Token

That is a code or a "key" to do work on your behalf

DeSec.io gives an API Token (think of it as a code) after a login, which is used internally by BushFire to do all the settings for your domain at their DNS service. This token is valid only for an hour or so -- You can save it somewhere and then reuse it for a limited time. if you get an error regarding the token; it means it is time to login once again. Or if you do not want to login, this is what you can do: Create a more permanent API Token

That can be done by visiting DeSec.io website and then login inside; and generate such an API Token -- which can last for a longer duration.

Worried that your account's API Token would be misused? Worry not. You can easily disable the earlier tokens that were generated at DeSec.io. That reminds me; you can always change your password at DeSec.io website; if you get worried about that too.
