No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Its good to have multiple revolving credit lines for a FICO score, but it doesn't have to be all secured cards which will probably get little use after you start getting approved for better cards. It doesn't take very long (maybe 6 months) if you have no more derogatorry marks on any accounts and a continuing positive history with those banks that gave you secured cards for them to approve you for a better card.
