A security key may be assigned to the user. The security key is divided into multiple parts that are distributed among electronic devices associated with the user. The security key can be reconstructed based on a distributed trust among the devices, where some devices may have a higher trust level than others. For example, each device can receive a number of key parts. In response to a request to authenticate the user, parts of the security key may be retrieved from two or more, but less than all, of the plurality of electronic devices associated with the user. The retrieved parts are used to reconstruct the security key, and the user is authenticated based on the reconstructed security key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for user authentication based on multiple devices","description":"A user may be authenticated using an authentication scheme based on user access to two or more selected electronic devices.
