[{"selector":"#anim-785814e8-e2a3-480a-822b-95581e656038","keyframes":{"opacity":[0,1]},"delay":200,"duration":2500,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5804c311-1043-4f63-82f5-8088a9c7dce9","keyframes":{"opacity":[0,1]},"delay":200,"duration":2000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-fc653e54-8658-4efc-8aa9-0b5f2a2dbda4","keyframes":{"transform":["translate3d(100.00000%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":200,"duration":2000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] WhatsApp currently allows similar choices to unlock its iOS app, but this goes farther.

WhatsApp says you may check if you have the capability under Settings > Account > Passkeys.
