1Password Stopped Working

  • After upgrading to Opera 53.0.2907.37 on My Mac, I now get the error: 1Password can't verify the identity of your browser. I've restarted Opera and my whole machine and the issue hasn't gone away.


  • I reported this to AgileBits yesterday and after doing some diagnostics with their team they reported:

    "All versions of Opera are now signed with a new certificate, one not known to 1Password 6. As a result 1Password cannot verify the browser code signature and when it can't it will refuse to connect. This will require an update to 1Password as the known certificates is a hardcoded list inside 1Password. I apologise as it means you won't be able to use Opera with 1Password for the moment."

    Going to file a ticket with Opera.

  • @nerd-thomas Thank you for starting this thread, good sir.
