This is great question! The basic requirements for new usernames are:
- They must be at least five characters long and start with a letter.
- Only letters and numbers should be used, no special characters, spaces nor symbols.
Usernames at Khan Academy are unique. If you try to pick one that is already in use, that username will be rejected. Try a new one!
