Configuring problematic antivirus/malware software

1Password manages the exchange of data between itself and the browser extensions through WebSocket connections. This allows the 1Password background process to communicate with the browser extensions while still respecting the “sandboxing” rules enforced by modern web browsers. Although they appear as network connections, they are limited to your local machine. These connections are also encrypted and authenticated, so they cannot be used to deliver information to any processes besides 1Password and its browser extensions.

If these WebSocket connections are blocked for any reason, though, 1Password cannot exchange data with its browser extensions. Many antivirus/malware and Internet security solutions also include a firewall and other “protective” features that prevent 1Password from performing its safe and secure functions.

Here are specific steps for configuring programs that have been seen to block 1Password’s secure WebSocket connections. Our support team may ask you to follow these steps as part of resolving problems on your system.
