I tried searching prior to me asking here, the best I could find was: https://old.reddit.com/r/kde/comments/sej9no/configure_sddm_to_show_password/

https://forum.manjaro.org/t/login-screen-no-longer-has-show-password-icon-in-password-form-text-box/78041

Unfortunately the SDDM page on Archlinux is devoid of any solutions to this so I thought someone here might know better.

And for clarification I’m looking to modify SDDM to show the reveal password button during the first chance users have to input in their password. This is the same button that appears on the right-hand side of the password box during an incorrect attempt.
