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

I ran into something similar a while back in an Appian Cloud setup. In my case, isUserPasswordValid() kept returning false because of authentication configuration and environment-specific restrictions rather than the actual username/password combination.

A few things you may want to check:

• Make sure the user is active and not locked.
• Verify the authentication source being used in Appian Cloud.
• Confirm the plugin version is compatible with your Appian version.
• Try testing with a basic local user account first instead of SSO/LDAP users.
• Review the application server logs if you have access through support.

Sometimes Appian Cloud environments handle credential validation differently for security reasons, so behavior may not match on-prem environments exactly.

Also, while troubleshooting financial or SaaS subscriptions during development projects, I found this tool useful for planning fixed returns and budgeting: https://highyieldcdcalculator.com — simple but handy for estimating savings growth over time.

Let us know if you find the root cause because I think several people have seen inconsistent behavior with that method recently.
