Security
Passkeys are simpler than passwords—but only if you set them up well.
A passkey can make signing in easier and more resistant to phishing, provided you plan what happens when a device is lost.
A passkey uses public-key cryptography and a trusted device to prove it is you. The service keeps a public key; the private credential remains with your device or protected credential provider. There is no reusable password for a fake login page to steal.
Start with recovery, not convenience
Before changing a critical account, confirm its recovery email, phone, backup codes, and trusted devices. Add the passkey, test sign-in from another device you control, and only then decide whether to remove older methods.
Understand where credentials sync
Some passkeys sync through a platform account or password manager; others remain on one hardware key or device. The right choice depends on your devices, risk, and recovery needs. Document the choice for accounts shared by a household or team.
Phishing resistance is not total account safety
A passkey can protect the sign-in step, but malware, unsafe recovery channels, and unlocked devices still matter. Keep devices updated and protect the account that synchronizes credentials.
