US Patent 10924931 External sharing with improved security

A computing system includes a processor and memory storing instructions executable by the at least one processor. The instructions, when executed, provide a user interface component that receives an indication of an external user with which to share an item of electronic content, a link generation component that generates a link to share the item of electronic content and identifies a communication endpoint associated with the external user, and an access control component that receives a request to access the item of electronic content using the link and, in response to the request, generates an access code that is communicated to the communication endpoint associated with the external user. The user interface component receives an access input, and the access control component grants access to the item of electronic content based on a determination that the access input includes the access code communicated to the communication endpoint associated with the external user.
