I have integrated universal login widget on my organization’s login page.
When the page loads the “Username” field shows red border around the input text box indicating there is an error. As it happens on loading of the page not sure which event triggers that.
It seems that the Universal Login page tried to proceed with logging in without actually providing any values for the username or email address field.
I did not experience this myself when loading the Universal Login page, but the red box indicates that the Continue button was pressed without any credentials provided for logging in.
I am curious if you would get a “Password is required” error if you attempt to call the login page with the login_hint=someemail@example.com query parameter. If so, then there must be some mechanism that is attempting to prematurely log in as soon as you load the page.
