If you head to the Settings tab at the top of the DeployHQ interface, then to Security on the left hand side, you'll be able to monitor and configure two important aspects of your user account.
Within the security tab, you'll be able to view and revoke any active browser sessions for your user account. You'll see a list of connections with associated IP addresses and a Logout button next to each one, which you can click to immediately revoke it.
Secondly, you'll see your personal API key which you can use for integrating with our API. You can disable it, or reset the key to generate a new one via the named buttons on the right hand side. Additionally, you'll be able to see the last time the key was used and the connecting IP address below it.
