There are some differences between usernames and nicknames, and their function in Khan Academy:
- Your username will appear in your Khan Academy profile URL (the long string starting with https:// at the top of the page).
- E.g.: https://www.khanacademy.org/profile/TestUsername123/
- You are able to use your username to log into Khan Academy, just as you can also log in using your email.
- This is how your name will appear around Khan Academy, and how your coaches and the Khan Academy community will recognize you.
- You cannot use your nickname to log into Khan Academy.
