Now I'll add the password visibility toggle with an eye icon. I'll update the login page to include state for showing/hiding the password and add the eye icon button:

Now I'll replace the password field section with the new one that includes the eye icon toggle:

I've added the password visibility toggle with an eye icon to the login page. The changes include:

1. Added Eye/EyeOff icons from lucide-react for showing and hiding the password
2. Added showPassword state to track password visibility
3. Created a password toggle button that switches between eye and eye-off icons when clicked
4. Wrapped the input in a relative container with the button positioned absolutely on the right side
5. Added proper accessibility with aria-label for screen readers

The eye icon is now fully functional - clicking it will toggle between showing and hiding the password text. The icon changes color on hover and respects the disabled state during login submission.
