## Description

Provides a complete workflow for implementing verified email retrieval on Android Credential Manager API. Use this skill to integrate a secure, OTP-less email verification flow into an Android app. This skill solves the problem of high-friction sign-up processes by leveraging cryptographically verified credentials from trusted providers like Google.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

## Fundamentals

- *[Overview of Digital Credentials](references/android/identity/digital-credentials/email-verification.md)*: Learn about cryptographically verifiable documents and the role of Credential Manager.
- *[Glossary](references/android/identity/digital-credentials/email-verification-implementation.md)* : Definitions for `dcql_query`, `UserInfoCredential`, and `GetDigitalCredentialOption`.

### Standards \& Examples

- *[OpenID4VP Standard](https://openid.net/specs/openid-4-verifiable-presentations-1_0.html#name-introduction)*: The specification used to create digital credentials requests.
- *[Digital Credentials Demo](https://digital-credentials.dev/)*: Example requests and cross-platform testing tool.
- *[W3C Verifiable Credentials](https://www.w3.org/TR/vc-data-model-2.0/)*: The data model for cryptographically secured claims.
- *[SD-JWT](https://datatracker.ietf.org/doc/draft-ietf-oauth-selective-disclosure-jwt/)*: Selective Disclosure JSON Web Token format used for responses.
- *[mdoc](https://www.iso.org/standard/69084.html)*: ISO/IEC 18013-5 standard for mobile documents.

### Requirements

- **SDK Version**: Minimum SDK 28 (Android 9) is required.
- **GMS Version**: Google Play services version 25.49.x or higher.

### Use Cases

Email verification is applicable for the following use cases:

- **Account Creation/Sign-up**: Remove friction by skipping manual email verification.
- **Account Recovery**: Securely verify email ownership during recovery flows.
- **Re-authentication**: Versatile verification for high-risk actions, independent of the initial sign-in method.

### Limitations \& Nuances

- **Workspace Accounts**: Google does not issue verifiable credentials for Google Workspace Accounts.
- **Freshness**: For non-@gmail.com addresses, Google verifies the email at account creation but there is no freshness claim; implement an additional challenge like an OTP.
