Description

I'm using v3.2.1 of react-native-auth0.

I'm using screen_hint in my authorize function to show the signup prompt in my 2 applications. It's working well for the one that is not using the connection props to target another tenant. When I'm using connection, screen_hint is not taking into account anymore. Maybe because a a redirection that occur afterward. The documentation is not very helping and have very few details about screen_hint.

Reproduction

Here screen_hint will not work (connection to another tenant is needed for this app)

const {accessToken, refreshToken} = await auth0.webAuth.authorize({
    additionalParameters: {
      screen_hint: 'signup',
    },
    audience: AUTH0_AUDIENCE,
    scope: AUTH0_SCOPE,
    connection: AUTH0_CONNECTION,
    maxAge: 0
});

This works (connection to another tenant not needed for the second app)

const {accessToken, refreshToken} = await auth0.webAuth.authorize({
      additionalParameters: {
        screen_hint: 'signup',
      },
      scope: AUTH0_SCOPE,
      audience: AUTH0_AUDIENCE,
      maxAge: 0,
 });

Hi @frArdouin,

When you specify a social connection value, the Auth0 Universal Login page is bypassed, and the other Identity Provider's login page is loaded.

The connection value is specific to Auth0. To configure your connection, check the options available for said connection in the Auth0 Dashboard.

In any case, this is not an SDK issue. If you still need assistance, please open an Auth0 support ticket.
