Pressing Option key to reveal hidden passwords stops working after restarting 1Password

Toggling "Hold Option to toggle revealed fields" off and back on may well help shake this loose, as mentioned above, so if you haven't tried that already, give it a go.

You can also try pressing ⌘R (Command–R) to show or hide concealed fields. This doesn't have a setting, so should always work.

If you can try both of those to see if they help when you notice that holding ⌥ Option doesn't work, that would be helpful in our research for this.
