How can an authorized user on a credit card become the primary user?

An authorized user on a credit card can become the primary user by requesting the primary account holder to transfer the account to their name. This usually involves contacting the credit card issuer to discuss the process, which may include a credit check and approval based on the authorized user's creditworthiness. Once approved, the authorized user will assume full responsibility for the account, including payment obligations. The primary account holder may also need to remove themselves from the account during this transition.
