I gather the change suits colorblind users better, but agree the tiny padlock badge isn’t ideal. Would recommend instead changing the icon appearance itself – e.g., some suggestions:
- Make the BitWarden shield black (or better, dark-gray) on a white BG when locked, which changes to the white shield on blue BG when unlocked (here the b/w inversion suits colorblind users); …or…
- Make the BitWarden shield itself the body of a padlock, with a shackle on top that’s open when the vault is unlocked, closed when locked.
