How to set up a passkey on X (Twitter)

A passkey lets you log in without typing your password. X says passkeys use public key cryptography from the WebAuthn standard: your device creates a key pair, X stores the public key, and the private key never leaves your device. Because the passkey is never shared with X, it's less exposed to phishing.

3. Select Settings and privacy, then Security and account access, then Security.

Keep a strong password even with a passkey set up, since it remains your fallback. Two-factor authentication is a separate setting under the same Security menu.

• Lost or stolen phone: X says the account stays secure and you can still log in with your password
• On Apple devices, passkeys sync through iCloud Keychain to devices signed in to the same iCloud account. X says that if you lose all your devices, they can be recovered through iCloud Keychain escrow
• Sharing: you can't share a passkey without sharing the iCloud account. For several people managing one business account, X points to its Delegate feature
