Abstract: The present disclosure relates to generating composite user identities in a distributed computing system. According to one embodiment, an example method generally includes transmitting, to a plurality of identity providers, a request for user identity information. A service provider receives, from a subset of the plurality of identity providers, the user identity information and selects a subset of the received user identity information to be used in verifying an identity of a user based, at least in part, on a reputation score associated with each identity provider in the subset of identity providers. The service provider generates a composite user identity based on the selected subset of the received user identity information. The service provider takes one or more actions to enable use of a service based on the generated composite user identity.
