Do not autofocus on field "user name" when local login is not first login method

[monnardj]

At our university, students and staff login with an IDP via a dedicated button. Consequently, this login is placed first on the login page (a great feature of Boost Union !). But we still enable local logins (which we call "External accounts") for users without an IDP account.

Unfortunately, when loading the login page, the focus is set automatically on the field "user name" for local logins. And many users with an IDP account (esp. new students) enter their IDP credentials in the local login form, which obviously won't work. This leads to many (unneeded) support requests.

Would it be possible to remove the autofocus from this field when local login is not the first method, either always or as an option ? From a UX point of view, I would argue that since this method is a secondary login, the focus should not go to this field automatically (other issues : it makes the page jump to the field, which may hide the IDP login button, depending on the window size; on mobile, it displays the keyboard or the password manager, which is useless at this stage).
