How to protect phone and computer to stop family from snooping after ctb?

[johnny]

What things can be done to prevent family (without extensive IT knowledge) from getting into your phone or PC? Is a simple password protection enough, or is there something else you would need to do?

Depends on how non-tech savy that family is, but even a person without a lot of knowledge can take the hard drives, put them into a different computer and access them through that. So unless you encrypt your stuff, it is very very easy to get access.

Well you could do a format on the PC, a factory reset on the phone and drop it in a bucket of water.

After format the partition table is deleted but data is still present on the disk and can be recovered using a data recovery software.
To avoid this you should format and then do multiple overwrites (but it might take a lot of time) or tear the HDD/SSD down and physically destroy the platters or the NAND flash.
