Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
If you forgot your credit card information, you can either
1. get it off your credit card, or
2. figure it out by contacting the bank that issued it, identifying yourself, and asking for it.
If you forgot your password ***** a site, you should be able to reset or retrieve it, by using your email address and the website's "Forgot password?" or similar link and subsequent processes.
If that is not helpful to the problem, then let me know more about why you would not have your credit card's digits, or what website's password ***** have forgotten, and I will advise you as appropriate.
