You’d better change your birthday – hackers may know your PIN Are you in the 26% of people who use one of these PIN codes to unlock their phones? June 19, 2019 https://www.welivesecurity.com/2019/06/19/change-birthday-hackers-may-know-pin/
Having just got a new phone I was wondering when I was getting it to recognise my finger print about the privacy aspect. Do finger prints or face ids get uploaded to manufactures server? Then a government may demand these and store them on their servers. Uk government departments break the law in that they don't destroy dna after 7? Years so no doubt they could these ids ad infinitum
If some1 else has physical access to your phone, don't expect a pin code to stop them. In fact my phone doesn't have a lock cuz it's always with me, except when I'm home ofc then I leave it
