Some exciting updates on identity & authentication from Google I/O

Hello developers,

We’ve had a busy couple of months and we’ve published new passkeys documentation, exciting Google I/O talks, code samples, and more.

Read on for the latest updates and resources to elevate your app’s identity and authentication solutions. 

Passkeys at Google I/O 

At this year’s I/O we’ve had several sessions on passkeys and identity solutions! Check them out on YouTube: 

• Passkeys and identity best practices

• How to use passkeys and FedCM for better sign-in and sign-up experiences

• Learn how Tiktok login rate improved 17x through passkeys integration 

Documentation Updates

• Android Identity Developer Hub: We’ve launched Android Identity Developer Hub, a comprehensive resource center tailored for developers looking to build robust authentication and identity solutions. Explore best practices, tutorials, and technical documentation to create seamless user experiences.

• Passkeys server-side guidance: We've published server-side guidance to implement passkeys. This guidance is platform-agnostic so the frontend can be implemented on desktop, Android, iOS or web. For server-side passkey implementations, we recommend using a library. Learn more about the recommended libraries and the criteria for selecting one at passkeys.dev. We've partnered with the W3C WebAuthn Adoption Community Group to create that guide.

• User verification, discoverable credentials, exclude credentials: Passkeys have a few complex concepts such as user verification, discoverable credentials or exclude credentials. We've got you covered. They are now explained in a platform-agnostic manner.

• Improved documentation for Sign in with Google: We have improved the documentation for Sign in with Google to make it more accessible and informative. 

Code Samples 

• Android’s credential provider sample: We've published a credential provider sample, which provides a reference implementation of the Credential Manager guidance for developers who want to create a credential provider app and to ensure consistency in the app ecosystem.

New Capabilities

• Promote upgrading to passkeys from the password manager: You can now upload a JSON file to your server to let password managers know that your website or app is eligible to register passkeys. Google Password Manager now supports this feature and promotes upgrading to passkeys.
