Young couples are sharing fingerprints to unlock each other's phones

Sara Salinas

As smartphones like those made by Apple and Google increasingly move toward biometric access, younger users lean on the convenience of a single tap or look, over traditional passcodes. For young couples, major relationship milestones used to look something like a borrowed letterman jacket or a shiny key to an apartment — a show of trust and commitment, and a means to say, what's mine is yours. Younger millennials and Gen Z teens, more tech-savvy and less privacy-keen than generations before, have kept the sentiment, but replaced lending their letterman jacket with swapping biometric passwords like a fingerprint or facial recognition ID to access their partner's phone.
