<p>Hi,<o:p></o:p></p>
<p>we are unsure if <em><span style="font-family:"Calibri",sans-serif">nonce</span></em> is OPTIONAL or REQUIRED in the Hybrid Flow.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:6.0pt;margin-right:0in;margin-bottom:6.0pt;margin-left:0in;text-indent:-.25in;mso-list:l0 level1 lfo1">

<em><span style="font-family:"Calibri",sans-serif">nonce</span></em> is REQUIRED.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:6.0pt;margin-right:0in;margin-bottom:6.0pt;margin-left:0in;text-indent:-.25in;mso-list:l0 level1 lfo1">

</span></span></span><![endif]><em><span style="font-family:"Calibri",sans-serif">Hybrid Flow => Authentication Request</span></em> (Section 3.3.2.1
<a href="https://openid.net/specs/openid-connect-core-1_0.html#HybridAuthRequest">
2</a>) refers to <em><span style="font-family:"Calibri",sans-serif">Code => Authentication Request</span></em> (Section 3.1.2.1
<a href="https://openid.net/specs/openid-connect-core-1_0.html#AuthRequest">3</a>), where
<em><span style="font-family:"Calibri",sans-serif">nonce</span></em> is OPTIONAL.<o:p></o:p></p>
<p>What does this mean for the case in which no nonce is used in the Authentication Request (OPTIONAL: nonce).<br>
Does the IdP have to generate its own nonce and include it in the ID Token (REQUIRED: nonce)?<o:p></o:p></p>
<p>Or is this a bug in the specification?<o:p></o:p></p>
