Author here. Mate, negativity just makes it harder for other voices to feel like they can be heard. Nobody should fear sharing their opinions… let’s be collaborative and show others how it’s done.

The approach I’m suggesting relies on the same secure enclave/TEE infrastructure passkeys use. Over 95% of iOS and Android devices are passkey-ready, TPM 2.0 is required for Windows 11 (although there are adoption issues here) but over a billion people have already activated a passkey. You’re right that coverage isn’t universal, but it’s broad enough to build on and beats uploading your passport to a third party.
