Hi! I understand you're having trouble logging into the Express Scripts app despite using the correct email and password. Let’s work together to figure this out.

To start, may I ask:
- Are you using the Express Scripts website or the mobile app?
- Have you recently changed your password or email address?
- Do you see any specific error message when you try to log in?
- Are you prompted for any two-step verification or a single-use code after entering your credentials?

Meanwhile, here are some initial steps that often help resolve login issues:

1. Double-check the email and password you’re entering—sometimes a small typo or extra space can slip in unnoticed.
2. Clear your web browser's cache and cookies. In Windows 10 with WebKit browsers, you can usually do this in the browser settings under Privacy or History.
3. Make sure your internet connection is stable.
4. If two-step verification is enabled, ensure you are entering the code correctly and that you’re using the latest code sent to your email or phone. If codes aren’t working, waiting 15 minutes and requesting a new code sometimes helps.
5. If none of these work, try resetting your password using the Express Scripts password recovery page here: https://www.express-scripts.com/recover/password

If you’ve already tried these or the problem persists, let me know the specifics you see, and I can guide you through the next steps!
