A joint credit card operates on the same premise but it’s not exactly the same thing.

Are there any downsides to having a joint credit card?

Some credit card issuers no longer offer joint credit cards. Adding an authorized user is an alternative for sharing a credit card. There is a downside to having a joint credit card that can’t be ignored. Both people are legally responsible for making the payments.
