system consists of a few components:</p> <ul> <li><strong>Relying party</strong>: In the passkey context, a relying party (RP for short) handles passkey issuance and authentication. The RP must operate a client — a website or app that creates passkeys or authenticates with passkeys — and a server for registering, storing and verifying credentials generated by the passkeys on the client. A passkey mobile application must be bound to a RP server domain using the OS provided association mechanism such as <a href="https://developer.android.com/training/sign-in/passkeys#add-support-dal">Digital Asset Links</a>.</li> <li><strong>Authenticator</strong>: A computing device such as a mobile phone, tablet, laptop or a desktop computer that can create and verify passkeys using the screen lock feature offered by the operating system.</li> <li><strong>Password manager</strong>: Software installed on the end user's device(s) that serves, stores and syncs passkeys, such as <a href="/identity/passkeys/supported-environments#google-password-manager">the Google Password Manager</a>.</li> </ul> <h2 id="registration_flow" data-text="Registration flow" tabindex="-1">Registration flow</h2> <p>Use the WebAuthn API on a website or the Credential Manager library on an Android app to create and register a new passkey.</p> <p>To create a new passkey, there are a few key components to provide:</p> <ul> <li><strong>RP ID</strong>: Provide the relying party's ID in the form of a web domain.</li> <li><strong>User information</strong>: The user's ID, username and a display name.</li> <li><strong>Credentials to exclude</strong>: Information about previously stored passkeys to prevent duplicate registration.</li> <li><strong>Passkey types</strong>: Whether to use the device itself ("platform authenticator") as an authenticator, or a detachable security key ("cross-platform / roaming authenticator"). Additionally, callers can specify whether to make the credential discoverable so that the user can select an account to sign in with.</li> </ul> <p>Once an RP requests creating a passkey and the user verifies it with a screen unlock, a new passkey is created and a public key credential is returned. Send that to the server and store the credential ID and the public key for future authentication.</p> <p><img src="https://developers.google.com/identity/passkeys/developer-guides/images/registration.png" class="no-filter" alt="Registration flow"></p> <p>Learn how to create and register a passkey in detail:</p> <ul> <li><strong>On web</strong>: <a href="https://web.dev/passkey-registration/">Create a passkey for passwordless logins</a></li> <li><strong>On Android</strong>: <a href="https://medium.com/androiddevelopers/bringing-seamless-authentication-to-your-apps-using-credential-manager-api-b3f0d09e0093">Bringing seamless authentication to your apps with passkeys using Credential Manager API</a></li> </ul> <h2 id="authentication_flow" data-text="Authentication flow" tabindex="-1">Authentication flow</h2> <p>Use the WebAuthn API on a website or the Credential Manager library on an Android app to authenticate with a registered passkey.</p> <p>To authenticate with a passkey, there are a couple of key components to provide:</p> <ul> <li><strong>RP ID</strong>: Provide the relying party's ID in the form of a web domain.</li> <li><strong>Challenge</strong>: A server-generated challenge that prevents replay attacks.</li> </ul> <p>Once an RP requests an authentication with a passkey and the user verifies it with a screen unlock, a public key credential is returned.

We know you'd be inclined to eliminate the weaker authentication method as soon as possible, but that may cause user confusion or leave some users behind. We recommend keeping the existing authentication method for the time being.</p> <p>There are a few reasons:</p> <ul> <li><strong>There are users in a passkey incompatible environment</strong>: Passkey support is expanding broadly across multiple operating systems and browsers, but those who are using older versions are not able to use passkeys yet.</li> <li><strong>The passkey ecosystem is yet to mature</strong>: Passkey ecosystem is evolving. The UX details and technical compatibility between different environments can improve.</li> <li><strong>Users may not be ready to live with a passkey yet</strong>: There are people who are hesitant to jump on new things. As the passkey ecosystem matures, they will get a sense of how passkeys work and why it's useful for them.</li> </ul> <h3 id="revisit_your_existing_authentication_mechanism" data-text="Revisit your existing authentication mechanism" tabindex="-1">Revisit your existing authentication mechanism</h3> <p>While passkeys make your authentication simpler and safer, keeping the old mechanisms is like leaving a hole. We recommend revisiting and improving your existing authentication mechanisms.</p> <h4 id="passwords" data-text="Passwords" tabindex="-1">Passwords</h4> <p>Creating strong passwords and managing them for each website are challenging tasks for users. Using a password manager built into the system or a standalone one is strongly recommended. By making a small tweak to the sign-in form, websites and apps can make a huge difference to its security and the sign-in experience. Checkout how you can make those changes:</p> <ul> <li><a href="https://web.dev/sign-in-form-best-practices/">Sign-in form best practices</a> (Web)</li> <li><a href="https://web.dev/sign-up-form-best-practices/">Sign-up form best practices</a> (Web)</li> <li><a href="https://developer.android.com/training/sign-in/passkeys#save-password">Sign in your user with Credential Manager</a> (Android)</li> </ul> <h4 id="two-factor_authentication" data-text="Two-factor authentication" tabindex="-1">Two-factor authentication</h4> <p>Though using a password manager helps users with handling passwords, not all users use them. Asking for an additional credential called one-time password (OTP) is a common practice to protect such users. OTPs are typically provided through an email, an SMS message or an authenticator app such as <a href="https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2">Google Authenticator</a>. Because OTPs are usually a short text generated dynamically valid only for a limited time-range, it lowers the probability of account hijacks. These methods are not as robust as a passkey, but much better than leaving users with just a password.</p> <p>If you select SMS as a way to deliver an OTP, checkout the following best practices to streamline the user experience to enter the OTP.</p> <ul> <li><a href="https://web.dev/sms-otp-form/">SMS OTP form best practices</a> (Web)</li> <li><a href="/identity/sms-retriever/overview">Automatic SMS Verification with the SMS Retriever API</a> (Android)</li> </ul> <h4 id="identity_federation" data-text="Identity federation" tabindex="-1">Identity federation</h4> <p>Identity federation is another option to let users sign in securely and easily. With identity federation, websites and apps can let users sign in using the user's identity from a third-party identity provider. For example, <a href="/identity/gsi/web/guides/display-google-one-tap">Sign in with Google</a> delivers great conversions for developers, and users find it easier and preferable to password based authentication. Identity federation is complementary to passkeys. It's great for signing up as the website or app can gain basic profile information of the user in a single step, while passkeys are great for streamlining reauthentication.</p> <p>Keep in mind, after Chrome phases out third-party cookies in 2024, some identity federation systems may be impacted depending on how they're built. To mitigate the impact, a new browser API called Federated Credential Management API (FedCM in short) is being developed. If you run an identity provider, <a href="https://developer.chrome.com/docs/privacy-sandbox/fedcm/#what-do-we-expect-will-be-affected">check out the details</a> and see if you'd need to adopt FedCM.</p> <ul> <li><a href="https://developer.chrome.com/docs/privacy-sandbox/fedcm/">Federated Credential Management API</a> (Web, FedCM)</li> <li><a href="/identity/gsi/web/guides/overview">Overview of Sign-in with Google for Web</a> (Web, Sign-in with Google)</li> <li><a href="/identity/one-tap/android/legacy-get-started">Overview of One Tap sign-in on Android</a> (Android, One Tap sign-in)</li> </ul> <h4 id="magic_links" data-text='"Magic Links"' tabindex="-1">"Magic Links"</h4> <p>Magic link sign-in is an authentication method where a service delivers a login link over an email so that the user can click it to authenticate themselves. While this helps users sign in without remembering a password, switching between the browser/app and the email client will be a friction. Also, as the authentication mechanism relies on the email, the email provider's weak security can put user's accounts at risk.</p> <h2 id="learning_resources" data-text="Learning resources" tabindex="-1">Learning resources</h2> <h3 id="web" data-text="Web" tabindex="-1">Web</h3> <p>To integrate passkeys onto your website, use the <a href="https://w3c.github.io/webauthn/">Web Authentication API (WebAuthn)</a>.
