FAQPage Schema

How do I implement OTP-less email verification on Android using digital credentials?▼

You can achieve OTP-less email verification by integrating Android Credential Manager APIs to retrieve cryptographically verified digital credentials using OpenID4VP requests, replacing traditional manual OTP workflows.

What is OpenID4VP and how does it work for Android authentication?▼

OpenID4VP is a protocol for handling digital credential requests that enables Android apps to securely retrieve verified user attributes like email addresses by processing SD-JWT payloads through Credential Manager.

Does Android Credential Manager support passkey creation during verified email retrieval?▼

Yes, Android Credential Manager supports passkey creation alongside verified email retrieval, allowing apps to simultaneously establish secure authentication methods during account creation and recovery flows.

How do I parse SD-JWT for verified email credentials in an Android app?▼

Parsing SD-JWT for verified email credentials involves decoding the selective disclosure JWT payload to extract cryptographically signed email attributes returned via OpenID4VP during the Credential Manager authentication flow.

What server-side validation safeguards are needed for Android digital credentials?▼

Server-side validation safeguards for Android digital credentials require verifying cryptographic signatures of SD-JWT payloads and validating OpenID4VP responses to ensure returned email credentials are authentic and untampered.

Can I use Credential Manager APIs for account recovery and sensitive action reauthentication?▼

Yes, Credential Manager APIs can be used for account recovery and sensitive action reauthentication by retrieving trusted digital credentials to verify user email identity without relying on traditional OTP workflows.
