If you spelled your email address wrong while creating a Roadpass, then you might be stuck on a page that says "We've sent you a verification email".
Since you won't be able to verify your account with the mistyped email, you'll need to use an incognito/private browser window to sign up for a new Roadpass with your correct email address. This would just be for the process of creating a Roadpass account with your correct email address so that you can complete the verification, then you can go back to a regular browser window for future use.
