   Future: At approximately 9:30 pm Eastern Time on Monday September 28th, Formstack Sign will undergo a migration to ensure faster and more reliable user authentication. There is no risk to documents in flight, and no risk of account data loss. There could be a small interruption to user sessions during the migration, which is expected to take nearly two hours.
