Get Email and Password for AWS Post Confirmation Lambda

Question

After a user confirms their email, we want to run a Post Confirmation Lambda in AWS.

This lambda will store the user's email and password to a database that is separate from Cognito, so we need to fetch these credentials from AWS.

We believe it should be possible from the event object, but we can't find anything about this in the official documentation.

Is it possible to fetch a user's email and password from AWS from within a Post Confirmation Lambda?

Answer 1

After inspecting vars(context) and event, it seems that it is impossible to get a user's password from within the post confirmation lambda itself, as these objects do not contain it.

Thanks to everyone who helped.
