Facing an issue with isUserPasswordValid() of the Credential Management plugin. Always returning false, even for a valid username and password.

AFAIK isUserPasswordValid() is a local/self-managed environment only function.
It does not work on Appian Cloud because Cloud uses SSO/federated authentication - passwords are not stored or validated locally by Appian.
docs.appian.com/.../Appian_Administration_Console.html

it will not work in Appian Cloud. What you are seeing (always returning false) is expected behavior.
isUserPasswordValid(username, password)
only works when:Appian stores and manages passwords locally (self-managed/on-prem environments)
In Appian Cloud:
Authentication is handled via SSO / Identity Provider (IdP) (example: SAML,Okta)
Passwords are NOT stored in Appian.
Appian has no ability to validate a password.

Thank you for your inputs.

Requirement: Create an WEB API that allows users to reset their password using their temporary password.

We are using:
- Appian Cloud
- Appian native authentication (not external authentication such as SAML or LDAP)

We would like to create a Password Reset API for Appian users.

Please provide your valuable inputs.
