login Hint
Parameters
value
Domain hint to send as hd=? parameter in OAuth request flow. Enables redirect to primary IDP by skipping Google's login screen. (https://developers.google.com/identity/protocols/OpenIDConnect#hd-param) Note: IAP does not verify that the id token's hd claim matches this value since access behavior is managed by IAM policies.
loginHint setting is not a replacement for access control. Always enforce an appropriate access policy if you want to restrict access to users outside your domain.
