Use a custom domain for your important accounts. That way, if you decide you don’t like Proton, you can move to Tuta or a different provider and recreate your addresses there. That way, the only thing you have to change is some DNS records.
I’m currently testing the paid version of tuta and proton.
Regarding the other services, as other said, keep things separate. Personally I use self hosted bitwarden for passwords and Synology drive for well, drive.
Straighten it, drill a small hole perpendicular to the hinge of one of your doors, put it inside and cover the hole up. If there’s enough time, add some paint to it, otherwise just use the sawdust mixed with some glue. The hole is certainly tiny enough to get unnoticed and any metal detector would hopefully pick up the larger metal hinge instead of the paperclip. Finally, if you also paint it up, it would practically be invisible. Just make sure you use a paint that doesn’t smell too strongly.
