Preserve `login_hint` query Param in hosted pages

Preserve login_hint query Param in hosted pages

Problem

Preserve the login_hint query param in hosted pages, especially when I start on a login page, and move around to a forgot password page, etc.

Note - this hint is part of the spec - ideally, we would keep track of this in our hosted flows.

Solution

Incorporate this parameter into the hosted login pages (authorize, forgot password, etc)

Alternatives/workarounds

Theme customization on your own.

Additional context

There may be considerations around caching and security with keeping a param like login_hint "around" in this way.

@jobannon can you please add additional information to this issue.

Is there a problem that we are trying to solve, or is there a workflow that a customer is trying to complete that would be solved if we made a change here?

In general we don't preserve any query parameters that are not necessary to complete oauth, or to complete a particular workflow.

Users were attempting to move between our Authorize Login Page and then forgot password page. They wanted to preserve the login_hint as this movement happened.

Using state and adjusting the freemarker templates is one solution. Ensuring that if we get a login_hint on our login page we preserve this value through most front-end pages could be another.
