Is your suggestion related to an experience ? Please describe.

This relates to supporting the password expiry feature in password grant type.[1]

Describe the improvement

This handler has only taken into consideration the POST_UPDATE_CREDENTIAL and POST_UPDATE_CREDENTIAL_BY_ADMIN events. But POST_ADD_USER event also need to be considered to support the password expiration feature in the password grant flow.

• Update the ‘IdentityUserMetadataMgtHandler’ by analyzing the password change handler

• Subscribe to “Add user’ event as that also contributes to last password update time.

• Default password expiry period should be configurable through the deployment.toml file
