How can I build my credit score without no credit?

To build your credit score without any existing credit history, consider applying for a secured credit card, where you deposit a certain amount as collateral, which then becomes your credit limit. Make small purchases and pay off the balance in full each month to establish a positive payment history. Alternatively, you can become an authorized user on a responsible person's credit card, which can help you benefit from their positive credit history. Additionally, consider applying for a credit builder loan, which involves borrowing a small amount and repaying it to improve your credit profile.
