I think if I were headed out of country i would make a full backup of my phone, then wipe it and set it up using my old gmail account that i only use for spam and stuff, fwd my reservations to that account. I would not install my normal accounts on it. I would not install my bitwarden either. I would keep everything minimal, use web UIs where possible. then when i return, it looks like I use my phone and didn't wipe it but I also live a boring life.

Small inconvenience for me, but better than dealing with bullies.
