FIDO2 is the standard that enables users to leverage common devices to perform authentication functions for online services rather than relying on traditional methods of what a person knows such as usernames or passwords.
Usernames and password credentials have been used since around the beginning of the information technology era. Many attacks are built around the inherent weaknesses of passwords (length, strength) or passwords management (re-use, etc.). Some pain points are specifically linked to passwords usage in online purchases.
The new authentication mechanisms reduce the ability and likelihood of being compromised. Biometrics or other secrets like passwords never leave the user’s device and can’t be compromised by a third-party.
To successfully enable FIDO2:
Enable the WebAuthn feature on your ReachFive account. Contact support to have this enabled.
From your ReachFive console:
Navigate to Settings > WebAuthn.
Configure the following:
Application name: the name of the application that is displayed to the user during the FIDO2 Registration or Authentication process. There are no particular restrictions on what you can use here.
Allowed origins: the list of URLs that are allowed to make calls to the API endpoints provided by ReachFive to perform the FIDO2 Registration or Authentication process.
For now, we provide support of the following FIDO2 features:
Add a new device to an existing ReachFive user account
Login with a registered device using compatible web browsers on a desktop computer or an Android mobile device (see FIDO Platform/Browser support for more details)
Further developments will include mobile SDK support and the FIDO2 Registration flow.
To let your user add a new device to his account, you can use the
addNewWebAuthnDevice method. Check the following page for complete documentation: SDK Core addNewWebAuthnDevice method. The user needs to be logged-in to perform this action.
To let your user log into ReachFive using the FIDO2 login process, you can use the
loginWithWebAuthn method. Check the following page for complete documentation: SDK Core loginWithWebAuthn method.
If you plan on using the widgets provided by ReachFive, you’ll have to enable the authentication via WebAuthn in the widget settings. Check the following page for more details: SDK UI showAuth method.
Refer to the FIDO2 guide to implement the FIDO2 authentication workflow on Android applications.
Once configuration is complete, your users are presented with the following screen.
|They have the choice of signing in using the FIDO2 biometrics flow or the usual password flow.|
- Relying party
The entity whose web application utilizes the Web Authentication API to register and authenticate users. In our context, this is ReachFive touch points.
- Authorization gesture
An authorization gesture is a physical interaction performed by a user with an authenticator as part of a ceremony, such as registration or authentication. By making such an authorization gesture, a user provides consent for (i.e., authorizes) a ceremony to proceed. This may involve user verification if the employed authenticator is capable, or it may involve a simple test of user presence.
- Roaming authenticator
A roaming authenticator is attached using cross-platform transports, called cross-platform attachment. Authenticators of this class are removable from, and can "roam" among, client devices. A public key credential bound to a roaming authenticator is called a roaming credential.
- Platform authenticator
A platform authenticator is attached using a client device-specific transport, called platform attachment, and is usually not removable from the client device. A public key credential bound to a platform authenticator is called a platform credential.
Short for the Web Authentication API, a specification written by the W3C and FIDO Alliance, with the participation of Google, Mozilla, Microsoft, Yubico, and others. The API allows servers to register and authenticate users using public key cryptography instead of a password.
