Abstract
Disclosed are various embodiments for distributing and verifying ephemeral security credentials of variable entropy across channels of communication of variable levels of security assurance. In one embodiment, a security credential is generated for a user account. A subset of a set of communication channels associated with the user account is determined based at least in part on respective measures of entropy and/or security assurance corresponding to individual ones of the set of communication channels. The security credential is divided into multiple portions. A corresponding portion of the portions is sent across individual channels of subset of channels. A client computing device is authenticated for access to the user account based at least in part on receiving the portions of the security credential.
