#cybersecurity zealots often shame humans for writing down their passwords, but as someone who just had to excavate the digital remains of a loved one who died suddenly:

*please* write down your credentials somewhere a trusted human can find them, especially your phone passcode and any primary passwords (like for email accounts, password manager, etc.)

the humans who care about you will need that access for many reasons; a "badass" threat model will only add helplessness to their grief
