Just cut off their fingers or remove their faces. That should log you into most things. :)

This is what password managers are for!

I'm kind of curious now about the rules for accessing a dead family members accounts and whether ownership is or can be transferred

Only the copy kept at their attorney's office. That's my plan.

Savings account box with password to LastPass. Die. Have loved one receive savings account box.

I think Google has a deadmans switch for this situation, my parents have set me as the contact so we don't lose family photos and get into everything else, just in case.

Don't wait until someone is dead to find out what to do - will most likely be too late, or will be lots and lots of hurdles to overcome.
