Hello! I understand you want to update the email and password related to your Murphy Drive Rewards app. Let me help you with that.

Could you please clarify if you want to:
1. Change the email address associated with your Murphy Drive Rewards account, or
2. Reset/change the password for your current email login on the app?

This way, I can guide you more accurately. Meanwhile, here’s a general path for updating your password in the Murphy Drive Rewards system:

1. Go to the Murphy Drive Rewards password recovery page: https://sspr.murphyusa.com/
2. Select "Forgot Password" to reset your password.
3. Enter your registered email address to receive a reset link.
4. Follow the link sent to your email to create a new password.

If you want to change the email address associated with your account, that usually requires logging into your account and updating your profile details or contacting support directly to verify identity and complete the change.

Please let me know which update you want to make, and whether you are able to access your current account now. That will help me provide the next best steps!
