bug: login with `loginHint` does not skip the username input

[ImSingee]

Describe the bug

If invoked with a loginHint, the username/email filled in correctly, but user still have to click "Sign in" again in the logto page.

For example, on the login page, the user has already input the email:

Call logto signIn method with a loginHint, then the user will be redirected to the following page:

The user has to click the Sign in again, this is a terrible UX.

Expected behavior

Show the page as if user clicks the Sign in in logto.

For example, directly navigate the user to the following page:

How to reproduce?

logtoClient..signIn({
      redirectUri: `${location.protocol}//${location.host}/login/callback`,
      firstScreen: "sign_in",
      loginHint: 'x@xxx.com`,
    });

Context

• [x] Logto Cloud
• [ ] Self-hosted, Logto version =
  • [ ] Container (Docker image)
  • [ ] Raw Node.js

BTW, I also try the identifier:sign_in, but it doesn't work either.

Thank you for your suggestion. In fact, this isn't a bug, but more like a feature request. It could be considered to support: automatically moving to the next step once the form is filled out. However, the reality is that it's hard to determine if the user still wants to modify the entered values after filling out the form, so it's more reasonable to let the user choose to proceed to the next step themselves.

Would you like to convert this issue to be a feature request and describe your needs? The team will review GitHub issues every week and have internal discussion to determine whether we should support those feature requests.
