Lock / Unlock
Animated lock / unlock icon
The Lock / Unlock animated icon toggles between two states on click in 0.33 s, a good fit for show and hide password fields. Click-to-toggle icons typically drive mute/unmute, show/hide password, menu/close, play/pause and like buttons.

Questions about the Lock / Unlock icon
›How do I keep the Lock / Unlock icon in sync with my own state?
Make it controlled: pass active and flip it in onClick, e.g. active={on} onClick={() => setOn(!on)}. true plays to the last frame and false back to the first; an icon that mounts with active already true starts there without animating, and with reduced motion it jumps instead of playing.
›How do I make Lock / Unlock an accessible button?
Put its events on a real button with the render prop: render={(events, icon) => <button aria-label="Lock / Unlock" aria-pressed={on} {...events}><span {...icon} /></button>}. The animation itself stays aria-hidden, and aria-pressed tells screen readers which state is on.
