Apple wants to eliminate passwords with Face ID/Touch ID Passkeys
It will allow users to use Face ID and Touch ID for account authentication, replacing good old passwords.
Apple has introduced a new passkey feature for iPhone, iPad, and Mac. In a WWDC developer session, Apple engineer Garrett Davidson presented a new passkey feature that Apple has been developing based on FIDO Alliance’s WebAuthn protocol. It will allow users to use Face ID and Touch ID for account authentication, replacing good old passwords.
When creating an account on a website or app using a passkey, you just need to add your username and then set authentication using Face ID or Touch ID. No password required. The end-to-end encrypted passkey is generated and stored on your Apple device and synced across other devices, of course, in your Apple account. Your credentials are saved even if Apple devices are lost, thanks to iCloud Keychain.
However, you’ll fall back on passwords if you’re using a non-Apple device. The passkey feature is currently in Technology Preview, meaning Apple is allowing developers to test it before it becomes production-ready.
Following is a chart from Apple comparing different authentication methods, from memorized passwords to “Passkeys in iCloud Keychain.”
Passwordless authentication is growing in popularity lately; Google and Microsoft have already implemented it. In fact, Microsoft in March noted that more than 200 million accounts are using a passwordless login method (via TNW).
