Hi there! I’m sorry to hear that the Denny's app is repeatedly asking you to reset your password, even when you use a different account. That sounds tricky. To get started, can you tell me if this happens right after you open the app, or after you try to log in? Also, are you connected to Wi-Fi or cellular data when this occurs?

Meanwhile, here are some steps we can try to troubleshoot this issue on your iPhone with iOS 18.7:

1. Force close the app and restart it: Sometimes the app might glitch temporarily. Swipe up from the bottom (or double-click home button) and swipe the Denny's app off the screen to close it, then open it again.

2. Clear app cache (via reinstall): iOS doesn’t allow clearing cache directly, but uninstalling and reinstalling the app resets cached data. Press and hold the Denny’s app icon, tap ‘Remove App,’ then go to the App Store and reinstall it.

3. Check your internet connection: Make sure your Wi-Fi or cellular data is stable. Try switching between them to see if it helps.

4. Confirm the app is updated to the latest version: Sometimes older app versions have bugs. Open the App Store, search Denny’s, and check if there’s an update available.

5. Try logging in through a browser: Use Safari or another browser to visit Denny’s website and log in with your accounts there. If you’re still prompted to reset your password or have other problems, the issue might be related to your account or backend.

6. Reset your password via website: Even though it keeps asking, try resetting the password from the website, then use the new password in the app.

If you’ve already tried some of these or if the problem continues, let me know, and we can dig deeper into account settings or look at potential server issues. Also, please let me know if you get any specific error messages or if the password reset emails arrive successfully.

Are you satisfied with this initial guidance, or shall we proceed with more advanced troubleshooting?
