Answer: ACCOUNTADMIN

The ACCOUNTADMIN role is the default role authorized to manage shares in the Snowflake Data Exchange. According to Snowflake documentation and the community discussion with 100% consensus and 3 upvotes, ACCOUNTADMIN has the necessary privileges to create, manage, and drop shares by default. While other roles like SECURITYADMIN or SYSADMIN can be granted these privileges, they do not have them by default. USERADMIN is primarily for user and role management, not share management.
