1. A system for securely accessing legacy data, the system comprising:
an enterprise server including at least a processor and a memory, the enterprise server configured to communicate with at least (a) a security token service configured to issue a security token, (b) a legacy access provider configured to receive the security token, and (c) a legacy system configured to store the legacy data;
the processor configured to execute instructions stored on the memory to cause the enterprise server to: (i) associate a first user account with the security token upon reception of the security token by the enterprise server from the security token service; (ii) communicate the security token from the enterprise server directly to the legacy access provider; (iii) cause the legacy access provider to initiate communication over a network directly with the security token service to request that security token service authenticate the security token; (iv) enable creation of a second user account after the legacy access provider verifies authentication of the security token; (iv) access the legacy system via the first user account and the second user account; and (v) cause at least the second user account to be deleted after a single use of the legacy system.
