1. A method of controlling access to a protected resource, comprising:

  • receiving a request to access a protected resource from a user not currently authenticated to access the protected resource;

    in response, and without additional user input, performing a confidence-based authentication discovery operation by;

    initiating federated single sign-on flow to each of one or more known and trusted identity providers with whom the user has previously authenticated;

    receiving results from the one or more flows, each result indicating whether an identity of the user as asserted in the flow is recognized by the identity provider with whom the user has previously authenticated; and

    analyzing information returned in the results from the one or more flows to generate a score indicating a confidence that an identity of the user matches an identity of a user that has previously authenticated to one or more known and trusted identity providers; and

    permitting access to the protected resource based on the score.
