Major tech companies like Google, Apple, and Microsoft support passkeys, ensuring device compatibility across smartphones, tablets, and computers.

You can easily manage your passkeys through services like Google Password Manager, which syncs your credentials across devices. By adopting a Google FIDO passkey, you greatly reduce the risks associated with password reuse and breaches, making your online experience safer and more efficient.

How Passkeys Are Created

Creating a passkey involves a straightforward registration process that begins once you sign in using an existing authentication method.

After signing in, you’ll be prompted to create a passkey. This process includes user authentication through local authentication methods, like biometric authentication, a local PIN, or a FIDO security key. During the key pair generation, your device generates a unique public/private key pair linked specifically to your account and the online service. The cryptographic keypair is created during registration to ensure robust security.

The private key is securely stored in your password manager or on a chosen security key, while the public key is sent to the online service to associate it with your account. You’ll need to confirm the creation of the passkey, guaranteeing both security and your consent.

Once confirmed, you can manage and update your passkey through your account’s security settings. If you choose to use a security key, remember that the private key won’t sync across devices, enhancing security.

This efficient passkey registration process guarantees that you can authenticate securely without needing traditional passwords, making your online experience safer and simpler. Additionally, passkeys are designed to eliminate password frustration, streamlining the login experience for users.

The Authentication Process

Once you’ve successfully registered your passkey, the authentication process begins when you attempt to sign in. You’ll start by entering your username on the sign-in page. The system checks for existing passkeys linked to your account and presents you with a list if multiple options are available. You simply select the desired passkey.

Next, local verification kicks in. You’ll need to authenticate using a local method, like biometric measurements (fingerprint or face scan) or a PIN. This step guarantees you have physical access to your device, and importantly, your biometric data isn’t transmitted to the online service—it stays secure on your device screen. In this way, the process eliminates password-related security challenges, enhancing your overall security.

After local verification, the challenge-response mechanism comes into play. The online service sends a challenge to your device, which uses the private key linked to your passkey to sign it. This signed challenge is then sent back to the service, which verifies it using the stored public key. If everything checks out, the sign-in process is complete.

If you need to access your passkey from another device, recovery options through cloud password managers help you manage your passkeys seamlessly.

Key Security Benefits

Many users find that passkeys offer considerable security benefits over traditional password-based systems. Passkey-based authentication provides strong phishing resistance since there are no passwords to steal, and the challenge-response mechanism verifies your device, blocking phishing intermediaries.
