• and
• one or more processors, configured to:
• receive, from a first user:
• a digital item designated for sharing with at least one second user,
• at least one communication point for the second user, and
• data related to the second user,
• execute an authentication process, by:
• generating one or more authentication questions from the data, and
• via the communication interface:
• providing, to the communication point, access to the authentication questions, and
• receiving respective responses to the authentication questions,
• determine an outcome of the authentication process based on a correctness of the responses, and
