java.lang.Object

com.serinity.accesscontrol.util.UsernameGenerator

public final class UsernameGenerator
extends Object

Utility class for generating unique, sanitized usernames based on email addresses.

This class provides a single static method generate(String) which takes an email address, removes any non-alphanumeric characters from the local part, converts it to lowercase, and appends a short random UUID suffix to ensure uniqueness.

Designed to be used when creating Profile entities to automatically generate immutable usernames.

Note: The class is declared final and has no public constructor, as it is a pure utility class.

// Example usage
String username = UsernameGenerator.generate("John.Doe@example.com"); // Result might be "johndoe_a1b2c3"
