Each time you restart the login process or request a new code, all previous codes become invalid. To make sure that you’re entering the most recent code, try these steps:
- Delete all previous emails you’ve received from Express Scripts that contain a code for two-step verification.
- Wait 15 minutes.
- Click “Resend code” or begin the login process again to get a new code.
For your single-use code to work, you must keep the two-step verification page open on your browser. If you leave the page and then log in again, you will need a new code.
