Abstract: Provided is a computer-implemented method for verifying a user identity, including: receiving, from a user device, authentication data for a user, the authentication data including an account identifier corresponding to an account with a first issuer institution; generating, with at least one processor and based at least partially on the authentication data, a passcode; communicating the passcode to the user device or a second device associated with the user; receiving, with at least one processor, a verification request comprising the passcode; and verifying, with at least one processor, an identity of the user based on validating the passcode.

Abstract: A system and method are disclosed. The system and method can receive user data for a plurality of users from a plurality of data sources. The system can generate a plurality of scores for the plurality of users based on the user data. The system can further receive criteria and scoring parameters from a plurality of requesting entities. The system can determine a subset of users with scores that satisfy the criteria and scoring parameters. Further, the system can perform additional processing involving the subset of users.
