Why Passkeys Are Replacing Passwords

Today we are talking about passkeys, and why they are replacing password-centric login.In this episode, Satish uses a simple real-life example first, then turns the idea into a practical technical mental model for engineers and curious builders.In Simple Terms with Satish: daily tech trends explained simply, with enough technical depth for builders.Production note: This episode uses authorized synthetic narration based on Satish's own voice. The topic, script, and final editorial approval are by Satish.Engineer notes:Exact technical references:- FIDO defines passkeys as cryptographic credentials tied to a user's account and approved through the device unlock process.- MDN says Web Authentication protects against phishing because signatures change with the website origin.- MDN says a stolen public key cannot authenticate without the private key.- W3C WebAuthn Level 3 describes passkeys as client-side discoverable public key credentials.- Google describes passkeys as standardized passwordless sign-in across devices, browsers, and operating systems.- FIDO Credential Exchange defines a secure-by-default format for transferring credentials, including passkeys, between credential managers.Sources:- https://fidoalliance.org/passkeys/- https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API- https://www.w3.org/TR/webauthn-3/- https://developers.google.com/identity/passkeys- https://web.dev/articles/passkey-registration- https://fidoalliance.org/fido-alliance-credential-exchange-specifications-overview/
