Hi there! I understand you're having trouble with your Resideo app password and verification code not working after you set them up. Let's work through this together to get you back into your app smoothly.

To start, could you tell me:
- Are you unable to log in with the password you created, or is the verification code sent to you not being accepted?
- Are you seeing any specific error messages when you try to enter your password or code?
- Have you tried any steps so far, like resetting the password or reinstalling the app?

Once I know a bit more, I can guide you step-by-step to troubleshoot this issue. Meanwhile, here's a general approach that often helps:

1. Double-check login details: Make sure the email/username and password you’re entering are exactly correct — no accidental spaces, capitalization errors, or typos.
2. Verify internet connection: Ensure your iPhone is connected to a stable Wi-Fi or cellular network since the app needs this to verify your credentials.
3. Reset your password: On the Resideo app login screen, tap “Forgot password?” and follow the prompts to reset it. This will send a verification code to your email. Make sure to check your spam/junk folder if you don't see it.
4. Check verification code timing: Verification codes typically expire after a short period. Try requesting a new code and enter it promptly.
5. App update or reinstall: Ensure your Resideo app is updated to the latest version on iOS 18.7. Sometimes reinstalling the app can clear glitches; just make sure you have your account info before uninstalling.
6. Device settings: Sometimes, if your iPhone’s date/time settings are off, it can affect verification codes. Go to Settings > General > Date & Time and enable “Set Automatically.”

If after these steps you’re still having trouble, we can look deeper into advanced troubleshooting like checking for known issues on iOS or your account status.

Let me know what you’ve tried and what behavior you see exactly, and we’ll take it from there!
