SSO Account Switch

I’m wondering if there is some kind of header to add, or some way where I can “force” a user when going to the SSO page to have to use their eve username and password to Authorize.

This is needed due to the tool I am creating will have support for multiple eve accounts on a single “website” account which can be authed by any character id coming back on login.

The only annoying thing so far is having to go to the SSO page, and click cancel, and then go back to the website manually and login with SSO, and then login, rather than just passing a header with it to say “User has to login ignoring how long ago they did login”.

Thanks
