Amazon sells notebooks designed for writing down passwords and web-site info with A-Z index tabs for sites. Could be useful for executor when a senior passes.
- what is the worst they could do -
Hopefully not much as I keep banking etc. apps in a Secure Folder (Samsung Galaxy mobi) which has it's own biometric challenge and auto-locks when I close it. The apps in the Secure Folder also have a biometric challenge on opening.
Of course, services such as a Amazon, Google and Microsoft want to move away from passwords for day-to-day access and instead use Passkeys based on public/private keys which have to be held electronically. Options are in a password manager, the TPM chip on a device or in a hardware enclave such as a Yubikey.
