Shared Item Account Selection

Techniques for sharing of items from online storage (e.g., cloud storage) are described herein. In at least some embodiments, sharing links can be configured as one-time sharing links that provide recipients with limited, one-time access to a shared item for the purpose of selecting or registering an account to use for subsequent access to the item. Recipients are able to select accounts they find most convenient for accessing a shared item without the owner/sharer of the item necessarily having contact information for those accounts or sending a link to the accounts. Selection of a one-time link initiates an authentication sequence that selectively provides an option to select a particular account. Once the one-time sharing link is redeemed, the one-time sharing link is invalidated for subsequent access to the item.
