An organization is using an internal application for printing documents that requires a separate registration on the website.
The application allows format-free user creation, and users must match these required conditions to comply with the company's user creation policy: -> minimum length: 3 -> usernames can only use letters, numbers, dots, and underscores -> usernames cannot begin with a number The application administrator has to manually change and track these daily to ensure compliance.
