Hi! Sorry to hear you're having trouble with the PAK IDENTITY app showing "Invalid credentials" and issues resetting the password with different emails. Let's get to the bottom of this together.

First, just to clarify a couple of things:
- Are you sure you are using the same email address or username that you originally registered with the PAK IDENTITY app?
- When you try to reset the password, do you receive a reset email at all, or no email arrives?
- Are you trying to log in using an email or a CNIC (identity card) number? Sometimes the app expects the CNIC number rather than email for login.

To start, here’s a step-by-step approach to try:

1. Double-check your login ID: Make sure you’re entering the correct CNIC number or email address exactly as you registered it—no extra spaces or characters.

2. Password reset step:
- Go to the password reset page in the app.
- Enter the registered email or CNIC.
- Check your email’s spam/junk folder for the password reset link.
- If you don’t see any email, it could be due to a mismatch or the app’s backend having sync issues.

3. App vs Website account difference: One user reported that even if they can log in on the NADRA website, the PAK IDENTITY app may not allow login with the same credentials. So it’s important to confirm if your app account setup is separate or not.

4. Clear app cache (on your Xiaomi Android 11 device):
- Go to Settings > Apps > PAK IDENTITY app > Storage.
- Tap “Clear Cache” and then try logging in again.

5. Update the App: Ensure you have the latest version of the PAK IDENTITY app from the Play Store.

If these don’t help, it may be an account-specific issue like account duplication or device registration problems as noted in some cases. In such cases:
- You might need to contact NADRA support directly via email at [email protected] for account verification and manual reset.
- You could also visit the nearest NADRA office or Pakistani embassy if possible, especially if you are overseas.

Would you like me to help guide you through clearing the app cache or checking the reset process in detail on your Xiaomi? Also, if you can share exactly what you input as login credentials (just the type, not sensitive info), that would help me assist better.

Looking forward to hearing from you! Are you satisfied with this initial approach?
