I’m using @okta/okta-signin-widget version 6.2.1 and calling the OktaSIgnIn.showSignInToGetTokens method. When I try to sign in with a valid email address and password, it works. But when I try to sign in with an app username instead of an email address, I get the errors “Unable to sign in” in the widget and “FAILURE: VERIFICATION_ERROR” in the System Log. I believe the latter error means that the app username can’t be found.
In the browser’s Developer Tools, I see a request to POST /api/v1/authn that contains the credentials I entered, but there’s no app client ID. Because app usernames are associated with apps, I’m not surprised that the request fails with 401.
Does the Okta Sign-in Widget support signing in with app usernames instead of email addresses?
