<p>Prevents the user from signing in with the specified external (SAML or social) identity provider (IdP). If the user that you want to deactivate is a Amazon Cognito user pools native username + password user, they can't use their password to sign in. If the user to deactivate is a linked external IdP user, any link between that user and an existing user is removed. When the external user signs in again, and the user is no longer attached to the previously linked <code>DestinationUser</code>, the user must create a new user account. See <a href="https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_AdminLinkProviderForUser.html">AdminLinkProviderForUser</a>.</p> <p>This action is enabled only for admin access and requires developer credentials.</p> <p>The <code>ProviderName</code> must match the value specified when creating an IdP for the pool. </p> <p>To deactivate a native username + password user, the <code>ProviderName</code> value must be <code>Cognito</code> and the <code>ProviderAttributeName</code> must be <code>Cognito_Subject</code>. The <code>ProviderAttributeValue</code> must be the name that is used in the user pool for the user.</p> <p>The <code>ProviderAttributeName</code> must always be <code>Cognito_Subject</code> for social IdPs. The <code>ProviderAttributeValue</code> must always be the exact subject that was used when the user was originally linked as a source user.</p> <p>For de-linking a SAML identity, there are two scenarios. If the linked identity has not yet been used to sign in, the <code>ProviderAttributeName</code> and <code>ProviderAttributeValue</code> must be the same values that were used for the <code>SourceUser</code> when the identities were originally linked using <code> AdminLinkProviderForUser</code> call. (If the linking was done with <code>ProviderAttributeName</code> set to <code>Cognito_Subject</code>, the same applies here). However, if the user has already signed in, the <code>ProviderAttributeName</code> must be <code>Cognito_Subject</code> and <code>ProviderAttributeValue</code> must be the subject of the SAML assertion.</p>
