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.
