Restarting your browser may resolve this issue. If not, click Get Help.

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.

What you should do

For all browsers

First, try restarting your browser. If you’re still having trouble, follow these steps to allow 1Password to use native messaging in your browser:

  1. Open Terminal, which is in the Utilities folder of your Applications folder.

  2. Copy and paste the following command and press Return:

     mkdir -p  ~/Library/Application\ Support/Google/Chrome

  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.

If you use Brave

If you use Brave, make sure you’re using Brave 0.17.19 or later. Earlier versions do not have support for native messaging.

If you use Chrome Canary

If you use Chrome Canary, follow these steps to allow 1Password to use native messaging in your browser:

  1. Make sure the 1Password app and your browser are both in the Applications folder.

  2. In Finder, choose Go > Go to Folder. Copy and paste the following path and press Return:

     ~/Library/Application Support/Google/Chrome/NativeMessagingHosts/

  3. Copy the file named 2bua8c4s2c.com.agilebits.1password.json to your desktop.

  4. Choose Go > Go to Folder. Copy and paste the correct path for your browser and press Return:
