Hi there! I’m sorry to hear that you're experiencing an "Authentication fail" message when trying to transfer money. That can be frustrating! Let's work together to figure this out.

First, could you tell me a bit more about your situation? Specifically:
- Have you recently changed your account password or enabled two-factor authentication (2FA)?
- Are you using the latest version of the PalmPay app?
- Have you encountered this issue with just this particular transfer, or does it occur every time you try to transfer money?

With this information, I can better assist you!

I recently created app log in password. I am using old app. It started today

Thanks for the details! Since you've just created a new app login password and you're using an old version of the PalmPay app, it could be the reason behind the "Authentication fail" message. Let's try a few steps to resolve this:

1. Update the PalmPay App: Make sure you have the latest version of the app. Go to the Google Play Store, search for "PalmPay," and see if there's an update available. Updating could fix any compatibility issues related to your new password.

2. Manually Enter Password: Sometimes, apps autofill passwords or remember old ones. Try manually entering your new password instead of letting it autofill.

3. Clear App Cache and Data: This can help fix temporary glitches:
- Go to Settings on your device.
- Tap on Apps & notifications.
- Find and tap on PalmPay.
- Select Storage & cache.
- Tap on both Clear Cache and Clear Storage.

4. Restart Your Device: After clearing the cache, restart your phone. A simple restart can often resolve minor app issues.

5. Reinstall the App: If the problem persists, consider uninstalling the PalmPay app and then reinstalling it from the Google Play Store.

Try these steps and let me know if you're still having trouble! I’m here to help!
