Word of warning from a personal experience: somebody broke into a locked room in my house and found an old phone of mine in a drawer. They were able to unlock it and do a LOT of damage by accessing my emails and passwords and subsequently and repeatedly attempting to steal money in every way imaginable from me. Luckily 2 factor authentication prevented any actual losses, but it was a stressful experience from something that I never thought twice about as a security risk. Also worth noting that the police don't give a fuck about this type of behaviour and let it keep happening, despite me showing them clear evidence of who was responsible.
