    • Disclosed methods include receiving, by a system, a request from a computing device for an information exchange between a first entity and a second entity, and then generating a first token request for a cryptographic token to be authorized to enable the exchange. In response to receiving an indication that authorization was declined, the system may cause the computing device to identify a different cryptographic token of a connected application. The different cryptographic token may be usable by the connected application to authenticate the first entity to a computer service associated with the connected application. The system may communicate with the computer service to approve use of the different cryptographic token by the system, and then generate a second token request for a substitute cryptographic token using information from the different cryptographic token. The system may complete, using the substitute cryptographic token, the exchange between the first and entities.
