Way back in the day there used to be something called a "secured" credit card. It was a great way for young adults to start a credit history. It worked like this...

Deposit X dollars in a savings account with the issueing bank/cu. Typical was $500. That became your credit limit.

In fact, I still have one of these cards hanging around after 20+ years that I use exclusively for phone/online purchases and nothing else.

Anyone know if they still issue these?
