MULTI-FACTOR AUTHORIZATION FOR AUTHORIZING A THIRD-PARTY APPLICATION TO USE A RESOURCE

摘要

Enhanced security for limited access through multi-factor authorization to cloud computing resources. The enhanced security is obtained by utilizing a personal security device to perform certain security operations as part of an authorization protocol such that an authorization grant is confirmed using two independent factors such as evidence of knowledge of a secret plus possession of a personal security device. The personal security device may also store an access token and perform cryptographic operations evidencing possession of the access token. Other systems and methods are disclosed.
