No, there are faster methods, but I didn’t want to dive into those until you got something working.
The best method is to use the keyboard shortcut Ctrl+Shift+L to auto-fill. If you happen to have more than one account stored for the same website (i.e., if your badge counter is greater than 1), then you can hit Ctrl+Shift+L repeatedly to cycle through the available login credentials for the site.
Alternatively, if you go to Settings > Options in the browser extension, you can enable the option Auto-fill on page load, which will automatically fill in the form as soon as you go open the login page.
