Opera extensions and desktop apps cannot be used together.

Hello @eggplant! 👋

Thank you for reaching out. Opera isn't a supported browser for 1Password which means that integration between the 1Password desktop app and the browser extension won't work.

On the Mac, we recently released a custom trusted browsers feature which allows you to add any browser with a valid code signature to 1Password for Mac. The team is hoping to bring this feature to Windows in the future but it's not available currently.

For the moment, if you'd like to have 1Password in your browser share a lock state with the desktop app so that it can use features like Windows Hello, you can switch to one of our supported browsers such as Chrome, Firefox, Brave, or Microsoft Edge.

Let me know if you have any questions.

Hey!

Its working - if you haven't tried have latest versions of 1Password, Opera, Plugin, Windows.

1. Open 1Password app
2. Go to Settings > Browser > Connect to additional browser > klick "Add Browser". A File-Window will open. Now navigate to installation Path of Opera or see 3.
3. Locate your Install Path of Opera 
   1. Right Click on Opera Logo and click "Properties"
   2. Copy the path of General/Location or Shortcut/Target
   3. Insert it in the File-Window and klick "Open"
4. Opera should now be added into the list. Try to Lock/Unlock 1Password via App or Browser Extension. It will/should lock/unlock either way.

Hope it works for you as well :-)
