Authentication is one of the most important parts of any modern mobile application — but authentication on Android doesn't have to mean building a separate flow for every credential type.
Jetpack Credential Manager provides a unified API that helps Android applications support modern authentication methods such as passkeys, passwords, and federated sign-in.
I created a visual cheat sheet to summarize the most important concepts and implementation considerations.
What is Credential Manager?
Credential Manager is a Jetpack API that provides a consistent interface for users to sign in to Android applications using different types of credentials.
Instead of your application managing completely separate experiences for every authentication method, Credential Manager provides a unified entry point.
Supported authentication methods include:
- 🔑 Passkeys — passwordless and phishing-resistant authentication.
- 🔒 Passwords — credentials stored by supported password providers.
- 🌐 Federated identity — such as Sign in with Google.
- 🪪 Digital credentials — support for the evolving digital-credential ecosystem.
Why should Android developers care?
Credential Manager can provide several important advantages:
1. Better user experience
Users get a consistent system-managed credential selection experience.
2. Stronger security
Passkeys can provide phishing-resistant, passwordless authentication.
3. One API
Your application can work with multiple credential types through a common Android authentication API.
4. Future-ready authentication
The API is designed around modern authentication methods rather than relying exclusively on traditional passwords.
How the flow works
A simplified authentication flow looks like:
User action → Credential Manager → System UI → Credential Provider → Authentication → Your App
The system can query available credential providers and present the appropriate authentication options to the user.
Your application then receives the resulting credential and handles the authentication response.
Important developer considerations
When implementing Credential Manager:
- Provide authentication options appropriate for your application.
- Prefer passkeys when they make sense for your authentication architecture.
- Handle successful and unsuccessful authentication states.
- Provide a useful fallback when no credential is available.
- Test authentication on real Android devices.
- Understand how credential providers and system-managed UI work.
- Keep your authentication and privacy design aligned with your application's security requirements.
The key idea
You don't need to think of modern Android authentication as:
Password OR Google Sign-In OR Passkey
Instead, think:
Credential Manager → Multiple authentication options → One consistent experience
That shift can make authentication easier to implement while giving users more secure and convenient ways to sign in.
