Content preview including sharable information

A computer-implemented method, comprising:

• receiving an instruction at a content management system to provide a preview of a content item that contains a portion of content of the content item, wherein the content item is associated with a unique identifier assigned by the content management system and stored at the content management system;
• obtaining a machine-readable code, by the content management system, distinct from the unique identifier, that provides access to the preview of the content item via the content management system, the machine-readable code being uniquely representative of the preview of the content item;
• and
• determining, in association with the preview of the content item and based at least in part on the machine-readable code, access permissions to the content item, the access permissions permitting access to the content item via the content management system.

A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a content management system, cause the content management system to:

• receive an instruction to provide a preview of a content item that contains a portion of content of the content item, wherein the content item is associated with a unique identifier assigned by the content management system and stored at the content management system;
• determine whether machine-readable code for accessing the preview of the content item, distinct from the unique identifier, has yet to be generated;
• generate and associate a machine-readable code for accessing the preview of the content item;
• and
• determine, in association with the preview of the content item and based at least in part on the machine-readable code, access permissions to the content item, the access permissions permitting access to the content item stored at the content management system.
