Passwordless Authentication & Passkeys
Passwordless authentication is a security method that allows users to access systems without entering traditional passwords. Instead, it uses alternatives like biometrics, security keys, or one-time codes. Passkeys are a modern implementation of passwordless authentication, replacing passwords with cryptographic keys stored on devices. This approach enhances security by reducing the risk of phishing and credential theft, while also offering a more convenient and user-friendly login experience.

❓ Frequently Asked Questions
What is passwordless authentication?
A login method that lets you sign in without a traditional password, using biometrics, security keys, or one-time codes to verify your identity.
What is a passkey and how does it differ from passwords?
A passkey is a modern credential that replaces passwords. It uses a public/private key pair; the private key stays on your device, and authentication uses biometrics or a connected device. It’s phishing-resistant and can sync across devices.
What methods support passwordless authentication?
Biometrics (fingerprint or facial recognition), hardware security keys (USB/NFC/Lightning), and one-time codes from authenticator apps or messages, plus device-based prompts or approvals.
How do passkeys work across devices and what should I consider?
Passkeys sync across devices via platform cloud services, allowing sign-in on a new device with your biometrics. Availability varies by service and platform. Enable backup/sync, keep devices secure, and have recovery options in case a device is lost.
