Hi! I understand you're having trouble with your Health app not accepting what you believe to be a valid password, and it might be having an issue capturing characters correctly. Let’s dig into this together.

To start, could you tell me if:
- The password was just recently changed or reset?
- The app prompts you with an error message "invalid password" or something else?
- You are entering the password manually or using a saved password manager or autofill?
- Have you tried uninstalling and reinstalling the app already?

In the meantime, I’ll suggest some straightforward steps to try first:

1. Restart Your Device: This can refresh system processes that might interfere with password recognition.

2. Manually Enter the Password: Avoid autofill just to rule out any input capture issues.

3. Check for App Updates: Ensure your Health app is up to date in case a bug fix related to password input is available.

4. Clear App Cache/Storage: Sometimes cached data can cause credential errors. Since you're on Windows via WebKit browser, you can try clearing browser cache related to the app or if it's a desktop app, clear its cache through settings.

5. Confirm Keyboard Input: Make sure your keyboard layout/region settings haven’t unintentionally switched and that your caps lock or num lock keys aren't causing incorrect characters.

If these steps don't solve it, we can explore:
- Resetting your password again and confirming via any account security email or SMS.
- Checking if your account has multi-factor authentication enabled, which sometimes requires an app-specific password instead of your usual one.
- Trying to log in on another device or browser to see if the issue is device-specific.

Could you please try the above and let me know what happened? Also, share any error messages exactly as they appear if you can.

I’m here to help you get this sorted out!
