<p class="MsoNormal">We have has requests from marketing teams to review SP’s being able to define scopes as optional vs mandatory.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Today our assumptions are the scopes requested in an openid connect request are optional. If the SP for instance askes for
<o:p></o:p></p>
<p class="MsoNormal">Scopes=(openid email phone) the user could select/deselect email or phone.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Instead of the SP having to give the user an error that the user can’t proceed because one of the attributes was not provided, the SP could instead ask for a failed authentication for any scope being de-selected.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is this a feature/experience that has come up with anyone else before?
<o:p></o:p></p>
<p class="MsoNormal">Is there any suggestion in how to support this without doing something too far off spec?
