1. A computer-implemented method comprising: generating, by a central server that has access to credential information, a one-time-use password; transmitting, by the central server, an instruction to a remote server to activate an application instance, the instruction including the one-time-use password; receiving, by the central server and from the remote server, a request for the credential information, the request including at least (i) the one-time-use password, and (ii) an unique identifier associated with the application instance; verifying, by the central server, (i) the one-time-use password that is included in the received request, and (ii) the unique identifier that is included in the received request; in response to verifying (i) the one-time-use password that is included in the received request, and (ii) the unique identifier that is included in the received request, invalidating, by the central server, the one-time-use password; and transmitting, by the central server, a secure message that causes the remote server to create a file that includes the credential information in a secure location on the remote server.
