If you see "couldn't connect to 1Password" in your browser

Get help when you can't use 1Password in your browser because the extension can't connect to the app.

The 1Password classic extension is no longer in development, so we’re unable to troubleshoot issues outside the scope of this article. Upgrade to the latest version of 1Password for Mac and switch to the improved 1Password browser extension for a more reliable experience.

About the message

1Password 6.8 for Mac introduced a more reliable method for saving and filling in browsers called native messaging.

Native messaging improves the performance and reliability of the 1Password classic extension, especially when proxies, antivirus, and other security software would otherwise interfere with 1Password. If 1Password is unable to detect support for native messaging in your browser, you’ll see this message.

Couldn't connect to 1Password

  3. Open 1Password. Hold down the Control and Option keys on your keyboard and choose 1Password > Quit 1Password Completely from the menu bar.

  4. Open 1Password again.

  5. Restart your browser.

  6. Follow the additional steps below if you use Brave, Vivaldi, or Chrome Canary.
