Adding Cognito custom attributes post pool creation?

Question

Is it possible to add Cognito additional custom or standard user attributes post pool creation and once the pool is being used?

In other words is the Schema for the pool totally locked or can we add more custom attributes to it?

Answer 1

On AWS Cognito, you have two types of attributes:

• Standard Attributes: These attributes were selected when the pool was created and cannot be changed.

• Custom Attributes: These attributes can be added. Once they are added, they cannot be removed or changed
