iOS 15 and macOS 12 take a step toward a future without passwords
Apple's next iOS 15 and macOS Monterey will show off a new feature named "Passkeys in iCloud Keychain," which aims to replace passwords with a more secure login mechanism. Instead of entering a string of text to log into an app or website, you may use Face ID, Touch ID, or a security key. iCloud then syncs the Passkeys across all of your Apple devices.
The feature is based on the WebAuthn standard, which has progressively gained acceptance from Apple, Google, Microsoft, and others over time. Apple implemented support for passwordless logins in Safari on iOS and macOS last year. However, the new strategy goes even farther, incorporating WebAuthn into app sign-ups and syncing your credentials across Apple devices via iCloud.
