1Password 6.8 for Mac introduced a more reliable method for saving and filling in browsers called native messaging.
What you should do
If you see this message right after updating 1Password, it doesn’t mean your browser lacks support for native messaging. Try restarting your browser.
Restarting Brave does not work or solve this.
Opera, Vivaldi, and Chrome Canary all seem to have fixes, but not Brave so here is the advice I am given as a 1Password user…
If you use another browser
If you use another browser and you see this message, you should contact the developer and ask them to support native messaging.
If your browser supports native messaging, and you still see this message, contact 1Password Support and let us know.
