Actually it's not. . . Samsung came out with a facial recognition system for their new phones and it turns out that even a so-so photo taken under poor conditions, such as a mug shot, can often unlock it. I'd say that is the worst password ever. LOL!
Did you notice that these scientists are learning their "science" from the global warming crowd? They are not bothering to do their science in the real world. . . which could be easily done. They are only doing it with "statistical models" in computers. . . using statistical models they built using assumptions of facts and accuracy they created and think are true. They don't go out and do any research to base those assumptions any reality as is noted by the statement that the manufacturers who are using fingerprint scans don't let them have any data about how they are doing it. . . LOL! This is STRAWMAN SCIENCE.
Yeah, I read that as well.
I feel you should have an actual password to access your phone and encrypt any files from prying eyes with an additional pass.
When traveling I offload stuff I don’t others to see and wipe the empty space so there is no way to access those files.
I also uninstall my browsers before boarding a plane and reinstall to ensure my history is gone.
My thing....
