# Local Credentials in Expo

We've expanded our Expo SDK with a new hook, `useLocalCredentials`, which combines the capabilities of Clerk's user management with the concept of _Local Authentication_ in native apps.

For applications that allow their users to log in with an identifier and a password, `useLocalCredentials` enables them to use biometric authentication like Face ID, or Touch ID, when they sign back into the app. So, the next time they need to provide their credentials, they can simply use their device's biometrics.

Credentials are stored securely on the user's device only when they first sign in and can later be retrieved only after the user successfully passes biometric authentication.

Visit the [Local Credentials guide](https://clerk.com/docs/references/expo/local-credentials.md) to learn more about how to integrate this into your Expo app today.
