A username is a unique name that you choose for yourself. It is the name that you use to log in to Duolingo. This is also the name that community members will see if you comment in the forum on the web.
When creating your username make sure that:
- It has a minimum of 3 characters
- It has a maximum of 16 characters
- Special characters or blank spaces are not allowed. (Please no profanity either)
Also, if a username is already taken, the system will show an error — so be creative!
