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 having the following sub-steps;

    initiating federated single sign-on (F-SSO) 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 F-SSO flows, each result indicating whether an identity of the user as asserted in the F-SSO 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 F-SSO flows to determine, based on generating a confidence score that an identity of the user matches an identity of a user that has previously authenticated to two or more known and trusted identity providers, whether the user is permitted to access the protected resource without authenticating using additional user input; and

    permitting access to the protected resource without authenticating using additional user input based on the confidence score;

    wherein at least one of the receiving, initiating, analyzing and permitting steps is carried out in software executing in a hardware element.
