<p dir="auto">I did some more investigation into this, and I agree using <code class="notranslate">id_token</code> as way to login into 3rd party service is not very standardized way of doing things, here is rare example of that being done: <a href="https://kubernetes.io/docs/reference/access-authn-authz/authentication/#openid-connect-tokens" rel="nofollow">https://kubernetes.io/docs/reference/access-authn-authz/authentication/#openid-connect-tokens</a></p>
<p dir="auto">While investigating 3rd option of exchanging <code class="notranslate">id_token</code> for <code class="notranslate">access_token</code> on 3rd party service seems most common way of doing things, which can be done today without adding <code class="notranslate">refresh_token</code>, only downside will be that Mobile app needs to acquire <code class="notranslate">access_token</code> as soon as user logs in and not later when actually needed.</p>
