A common feature on login screens is the 'eye' symbol so people can double-check the password they are typing if they are in an environment safe from people looking over their shoulder.
Would this fit in with this module?
GitLab's sign in screen for reference:
It uses SVGs for the regular and line-through-it eyes.
Also it has tooltips "Hide password" etc when hovering over the eye and probably similar message for accessibility.
Closed: works as designed
