GrapheneOS has Duress PIN now. Trezor has the Wipe code.
How do I remember them? How do I make sure I know them when I need them?
I have a routine to do a Backup Check drill every month.
I have a reminder with a checklist similar to this:
- [ ] Is;sync between my devices working?
- [ ] I manually check/copy long term backups.
- [ ] Is my online stash for emergency recovery working? Do I know the login & pass? I upload newest version of encrypted password managed to the online stash.
- [ ] Do I know the Duress PIN / Wipe code?
It's line an evac/fire emergency drill. You do it regularly so you don't forget how to do it.
