<p>Replaces the existing list of server certificate thumbprints associated with an OpenID Connect (OIDC) provider resource object with a new list of thumbprints.</p> <p>The list that you pass with this operation completely replaces the existing list of thumbprints. (The lists are not merged.)</p> <p>Typically, you need to update a thumbprint only when the identity provider certificate changes, which occurs rarely. However, if the provider's certificate <i>does</i> change, any attempt to assume an IAM role that specifies the OIDC provider as a principal fails until the certificate thumbprint is updated.</p> <note> <p>Amazon Web Services secures communication with some OIDC identity providers (IdPs) through our library of trusted certificate authorities (CAs) instead of using a certificate thumbprint to verify your IdP server certificate. These OIDC IdPs include Google, Auth0, and those that use an Amazon S3 bucket to host a JSON Web Key Set (JWKS) endpoint. In these cases, your legacy thumbprint remains in your configuration, but is no longer used for validation.</p> </note> <note> <p>Trust for the OIDC provider is derived from the provider certificate and is validated by the thumbprint. Therefore, it is best to limit access to the <code>UpdateOpenIDConnectProviderThumbprint</code> operation to highly privileged users.</p> </note>
