Fido

AI-generated Key Takeaways

The Fido class serves as the entry point for Fido APIs, which are based on the Fast IDentity Online industry standard for security keys.
Several constants are defined for retrieving data from Activity Intents, including JSON responses, PublicKeyCredential objects, and deprecated error/response extras.
There are static methods to obtain instances of Fido2ApiClient , Fido2PrivilegedApiClient , and U2fApiClient for both Context and Activity environments.
Some constants related to retrieving FIDO2 error and response data from Intents are deprecated, with the recommended approach being to use FIDO2_KEY_CREDENTIAL_EXTRA .

public class Fido extends Object

FIDO (Fast IDentity Online), which is the industry alliance where Security Keys are being standardized.

Constant Summary

String	FIDO2_JSON_RESPONSE_EXTRA	The key used by the calling `Activity` to retrieve a JSON-formatted string from the Intent received by `Activity.onActivityResult(int, int, Intent)` after launching `Fido2PendingIntent` .
String	FIDO2_KEY_CREDENTIAL_EXTRA	The key used by the calling `Activity` to retrieve `PublicKeyCredential` from the Intent received by `Activity.onActivityResult(int, int, Intent)` after launching `Fido2PendingIntent` .
String	FIDO2_KEY_ERROR_EXTRA	This constant is deprecated. use `FIDO2_KEY_CREDENTIAL_EXTRA` to fetch `PublicKeyCredential` instead. `PublicKeyCredential` contains an `AuthenticatorErrorResponse` .
String	FIDO2_KEY_RESPONSE_EXTRA	This constant is deprecated. use `FIDO2_KEY_CREDENTIAL_EXTRA` to fetch `PublicKeyCredential` instead. `PublicKeyCredential` contains an `AuthenticatorAttestationResponse` or an `AuthenticatorAssertionResponse` .
String	FIDO_CREDENTIAL_JSON_EXTRA	The key used by the calling `Activity` to retrieve `PublicKeyCredential` from the Intent received by `Activity.onActivityResult(int, int, Intent)` , as a JSON-formatted string after launching the Fido2 registration or Fido2 sign intent.
String	KEY_RESPONSE_EXTRA	The key used by the calling `Activity` to retrieve `ResponseData` from the Intent received by `Activity.onActivityResult(int, int, Intent)` after launching `U2fPendingIntent` .
