I have a lot of relatives who look to me for tech support. I used to have them choose their own passwords, or tell them to change it if I set one for them (they never change it). Then, inevitably, I’d have to help them reset those passwords the very next time they need to log in on a new device, or their sessions expire.
I tried to set them up with password managers, and some picked it up (my siblings). Others quickly forgot their master password, meaning I then had to sort out recovering ALL their various accounts.
Once I literally used a known exploit to hack into an old android tablet that my youngest sibling managed to forget the screen-lock for.
Now I just shamelessly save a bunch of other people’s passwords, pin-codes and other access details using my password manager, because they literally do not care. And it’s straight up more secure than the post-it notes some of them would use if I let them. They know I do this, I’ve made it clear that if they want my help but won’t follow my advice when I’m not there, making my life harder, further help comes with giving me unreasonable levels of access to their digital lives.
I’ve never misused it, and I never will. I take steps to be extra secure because I know I’m a single point of failure should my password database ever be breached somehow. But I could ruin dozens of lives.
