Alphanumeric input refers to a combination of letters (both uppercase and lowercase) and numbers. It is commonly used in various applications, such as passwords, usernames, and data entry fields, to allow for a broader range of characters and enhance security. This type of input excludes special characters and typically requires users to create more complex and unique identifiers. Alphanumeric input is essential for ensuring data integrity and user authentication in digital systems.
