Is Step a secured credit card?

Could you please clarify for me whether Step is indeed considered a secured credit card? I'm trying to gather information about different credit options and I've come across Step as a potential choice. I understand that secured credit cards typically require a deposit as collateral, but I'm unsure if this applies to Step. Could you elaborate on the security features and any deposit requirements associated with Step, if any? I appreciate your help in clarifying this matter.
