Error message: "Username already in use"
If you see this error message, it means the HBO GO ID (username) that you entered has been taken. Each HBO GO profile must have a unique HBO GO ID. If you get this message, do either of the following:
- Enter a different HBO GO ID (3-14 characters, with no spaces or special characters).
- Contact us to unlock your old HBO GO profile.
Note Unfortunately, even if you contact us to unlock your HBO GO profile, your Watchlist, Continue Watching list, and parental controls will all be reset.
