+### Setting new password with AWSSRP
+
+If you try to change the password with the `Cognito.change_password()` you
+might come across following error:
+
+```
+  File ".../warrant/__init__.py", line 196, in check_token
+    raise AttributeError('Access Token Required to Check Token')
+AttributeError: Access Token Required to Check Token
+```
+
+which was asked for in a number of issues. The correct approach is to use
+`AWSSRP.set_new_password_challenge()` as shown below:
+
+```python
+import boto3
+from warrant.aws_srp import AWSSRP
+
+client = boto3.client('cognito-idp', region_name='region')
+aws = AWSSRP(username='username', password='password', pool_id='user_pool_id',
+             client_id='client_id', client=client)
+tokens = aws.set_new_password_challenge('new_password')
+```
