When first logging in (on Chrome, win10) as I type my password and if I think I have hit a wrong key, selecting the eye to see what I have typed sends the cursor back to the start of the line so if not watching carefully you type the wrong password.
I don’t think that this should be like this?
I faced the same issue on the bitwarden mobile app and opened an issue on GitHub. The issue is now fixed on the mobile app.
I suggest you to open an issue on GitHub - bitwarden/browser: The browser extension vault (Chrome, Firefox, Opera, Edge, Safari, & more).
