I also want to authenticate with U2F.

Hi,

To authenticate using U2F in OutSystems, you can use the U2F Forge component or write custom code using the U2F API. Here are the high-level steps for authentication using U2F in OutSystems:

First, the user needs to register their U2F security key with your OutSystems application.

During the registration process, the OutSystems application generates a public key and sends it to the user's U2F security key, which stores the public key and creates a private key.

When the user wants to authenticate, the OutSystems application generates a challenge and sends it to the user's U2F security key.

The user's U2F security key uses its private key to sign the challenge and sends the signed challenge back to the OutSystems application.

The OutSystems application verifies the signed challenge using the public key obtained during the registration process. If the verification is successful, the user is authenticated.

To authenticate using FIDO2 in OutSystems, you can use the FIDO2 API or a Forge component that implements the FIDO2 API. The steps for authentication using FIDO2 are similar to the U2F authentication steps, with the main difference being that FIDO2 supports both passwordless and password-based authentication. For more details on how to authenticate using FIDO2 in OutSystems, refer to the FIDO2 API documentation and the documentation of any FIDO2 Forge components you may use.
