Your Grasshopper username is most likely the email address you signed up with. If you do not remember your username, refer back to the Welcome email sent to you when you created your Grasshopper account.
However, if you are an Admin on your Grasshopper account you can view the your username along with all the users on your Grasshopper account. To do this, do the following:
- Log in at https://portal.us.grasshopper.com/login.aspx.
- Go to Settings > Users.
- Click Edit, next to a user's name. The user's name, email, and username displays.
If you still can't log in, try contacting customer support using the contact options below.
