Frequently Asked Questions
How are usernames generated?
Usernames combine a random adjective, a first name, and a random number. Example: cool_james42. This creates unique, readable usernames.
Are these usernames guaranteed unique?
While collisions are unlikely due to the random number component, uniqueness is not guaranteed. For production use, always check against your database.
Can I customize the username format?
The current format is adjective_name_number. For custom formats, you can use the output as a starting point and modify as needed.
Are these suitable for production use?
These are designed for testing and development. For production username suggestions, consider adding more entropy and checking availability.
