<prompt> Human: Added as authorized user, I never gave my permission, and she never gave my social security number. Now the card is showing up in my credit report as a new account. Assuming this affects my average age of accounts, how can I erase its existence from the face of the Earth?  <response>: Ask her to remove you as an authorized user, and it should disappear from your credit report too. If its not, inform the credit agency of the situation and ask they remove it. Credit reporting agencies are more than happy to remove old accounts where you used to be an authorized user, since it was never an account you were legally responsible for.As long as youre only an authorized user, and not a co-signer, any impact on your credit score should be pretty minimal regardless.
