Systems, methods, and computer-readable media for restricting mobile device services between an occurrence of an account change and an acquisition of a security code. The method includes recognizing that a low level of security is in effect in association with a user device, or a set of credentials associated therewith. In accordance with the low level of security, an indication is provided to restrict one or more services initially provided for the user device, or the set of credentials associated therewith. In addition, an indication is provided to initiate an authentication event. Performance of such an authentication event results in the user device, or the set of credentials associated therewith, obtaining a security code that results in application of an increased level of security in effect in association with the user device, or the set of credentials associated therewith.
