If you want to improve your credit score in as little as 30 days, one way to do that is by becoming an authorized user. See if you have family or friends with good credit who will help you with your struggling credit by adding your name as an existing user on the credit card. It will only work the credit card is current and available.

By becoming an authorized user on an established account, the borrower’s available credit may rise, which in turn can lower their debt-to-income ratio. This may help boost a credit score quickly.
