Hi! I see that you're experiencing a loop in the PECO app where it keeps asking you to enter and verify the security code repeatedly. Let’s work through this together to get it resolved.

To start, can you tell me if you recently changed your phone, updated the app, or made any changes to your account or phone number? Also, are you logged in or trying to log in from more than one device at the same time?

Assuming no multi-device conflict, here are some steps to try that often resolve security code verification loops on iPhones with iOS 18.6:

1. Force Close and Restart the App
- Swipe up from the bottom of the screen and hold briefly to open the app switcher.
- Find the PECO app and swipe it off the screen to close it completely.
- Reopen the app and try entering the security code again.

2. Check Internet Connection
- Make sure you have a stable internet connection, either Wi-Fi or cellular data.

3. Clear App Cache or Reinstall
- iOS doesn’t allow manual cache clearing, but uninstalling and reinstalling the app refreshes everything.
- Touch and hold the PECO app icon, tap "Remove App," then delete.
- Go to the App Store, download, and reinstall the PECO app.

4. Verify Contact Information
- Ensure your phone number and email linked to your PECO account are up to date, as verification codes depend on this.
- You can check this on PECO’s website if you can login there.

5. Restart Your iPhone
- Sometimes, a simple restart can clear temporary glitches.

6. Verify No Account or Server Issues
- Sometimes server-side issues cause loops. If possible, check if PECO’s service status page or customer support reports any ongoing problems.
- You can also contact PECO support at [email protected] if the problem persists beyond these steps.

If you have tried some of these already, let me know which ones so I can help you with more specific advanced troubleshooting.

Does this help? Would you like me to walk you through any particular step?
