I don't know about today, but in the 1980s, "water resistant" for wristwatches meant that you could wash your car and the hose-spray wouldn't turn it into a brick. Can today's "water resistant" smartphone be dropped into a swimming pool with no ill effects? I don't know. But "resistance" as a marketing term is often far overblown, even with strict product standards in place, and for cryptography/authentication there is zero consumer protection or transparency. Any accountability for service providers is usually lip service anyway. Read your software licenses: there are no warranties, for any purpose, ever.
