# Disassociating faces from a user


You can use the [DisassociateFaces](https://docs.aws.amazon.com/rekognition/latest/APIReference/API_DisassociateFaces.html) operation to remove the association between a user ID and a face ID.

**To disassociate faces (SDK)**

1. If you haven't already:

   1. Create or update a user with `AmazonRekognitionFullAccess` permissions. For more information, see [Step 1: Set up an AWS account and create a User](setting-up.md#setting-up-iam).

   1. Install and configure the AWS CLI and the AWS SDKs. For more information, see [Step 2: Set up the AWS CLI and AWS SDKs](setup-awscli-sdk.md).

1. Use the following examples to call the `DisassociateFaces` operation.

------
#### [ Java ]

   This Java example removes the association between a FaceID and a UserID with the `DisassociateFaces` operation.

   ```
   import java.util.Arrays;
   import java.util.List;
   
   import com.amazonaws.services.rekognition.AmazonRekognition;
   import com.amazonaws.services.rekognition.AmazonRekognitionClientBuilder;
   import com.amazonaws.services.rekognition.model.DisassociateFacesRequest;
   import com.amazonaws.services.rekognition.model.DisassociateFacesResult;
   
   
   public class DisassociateFaces {
   
       public static void main(String[] args) throws Exception {
   
   
           AmazonRekognition rekognitionClient = AmazonRekognitionClientBuilder.defaultClient();
   
           /* Replace the below configurations to allow you successfully run the example
   
              @collectionId: The collection where user and faces are stored
              @userId: The user which faces will get disassociated from
              @faceIds: The list of face IDs that will get disassociated from the given user
            */
   
           String collectionId = "MyCollection";
           String userId = "demoUser";
           String faceId1 = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
           String faceId2 = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
           List<String> faceIds = Arrays.asList(faceid1,faceid2);
   
           System.out.println("Disassociating faces from existing user: " +
                   userId);
   
           DisassociateFacesRequest request = new DisassociateFacesRequest()
                   .withCollectionId(collectionId)
                   .withUserId(userId)
                   .withFaceIds(faceIds)
   
           DisassociateFacesResult result = rekognitionClient.disassociateFaces(request);
   
           System.out.println("Successful face disassociations: " + result.getDisassociatedFaces().size());
           System.out.println("Unsuccessful face disassociations: " + result.getUnsuccessfulFaceDisassociations().size());
       }
   
   }
   ```

------
#### [ AWS CLI ]

   This AWS CLI command removes the association between a FaceID and a UserID with the `DisassociateFaces` operation.

   ```
   aws rekognition disassociate-faces --face-ids list-of-face-ids
   --user-id user-id --collection-id collection-name --region region-name
   ```

------
#### [ Python ]

   The following example removes the association between a FaceID and a UserID with the `DisassociateFaces` operation.

   ```
   from botocore.exceptions import ClientError
   import boto3
   import logging
   
   logger = logging.getLogger(__name__)
   session = boto3.Session(profile_name='profile-name')
   client = session.client('rekognition')
   
   def disassociate_faces(collection_id, user_id, face_ids):
       """
       Disassociate stored faces within collection to the given user
   
       :param collection_id: The ID of the collection where user and faces are stored.
       :param user_id: The ID of the user that we want to disassociate faces from
       :param face_ids: The list of face IDs to be disassociated from the given user
   
       :return: response of AssociateFaces API
       """
       logger.info(f'Disssociating faces from user: {user_id}, {face_ids}')
       try:
           response = client.disassociate_faces(
               CollectionId=collection_id,
               UserId=user_id,
               FaceIds=face_ids
           )
           print(f'- disassociated {len(response["DisassociatedFaces"])} faces')
       except ClientError:
           logger.exception("Failed to disassociate faces from the given user")
           raise
       else:
           print(response)
           return response
   
   def main():
       face_ids = ["faceId1", "faceId2"]
       collection_id = "collection-id"
       user_id = "user-id"
       disassociate_faces(collection_id, user_id, face_ids)
   
   if __name__ == "__main__":
       main()
   ```

## DisassociateFaces operation response


The response for `DisassociateFaces` includes the `UserStatus`, which is the status of the disassociation request, as well as a list of `FaceIds` to be unassociated. A list of `UnsuccessfulFaceDisassociations` is also returned. After submitting a request to DisassociateFaces, the operation may take a minute or so to complete. For this reason, the UserStatus is returned, which can have the following values: 
+ CREATED - Denotes that the ‘User’ is created successfully and no faces are associated to it currently. ‘User’ will be in this state before any successful ‘AssociateFaces’ call is made.
+ UPDATING - Denotes that the ‘User’ is being updated to reflect the newly associated/disassociated faces and will become ACTIVE in few seconds. Search results may contain ‘User’ in this state and customers can choose to ignore them from the returned results.
+ ACTIVE - Denotes that the** ‘**User**’ **is updated to reflect all associated/disassociated faces and is in a searchable state.
