Spring Security – Integrate Passkeys Example
- Passkeys are a passwordless authentication method based on public-key cryptography, resistant to various attacks.
- They are built on WebAuthn and FIDO2 standards, supported by major ecosystems like iOS, Android, Chrome, and Windows.
- Passkeys offer convenience and security by syncing across devices through cloud providers.
- To integrate passkeys in Spring Boot, WebAuthn4J library is used for WebAuthn/FIDO2 support.
- Dependencies for WebAuthn support in Spring Boot applications involve the webauthn-spring-security library.
- Configuration files and classes like Security Config, Entity File, Repository File, Register Controller, and Authentication Controller manage passkey integration.
- The Register Controller handles user registration using WebAuthn data and stores public key and metadata in the database.
- The Authentication Controller verifies login attempts, updates signature count, and responds based on validation results.
- Secure authentication using passkeys in Spring Security enhances user experience and system security.
- Integration of passkeys with WebAuthn4J in Spring Security ensures a future-ready approach to secure authentication.
