If you need to change your username or password for any reason, changing the information in your Reflex profile is easy. Simply log into your teacher account and select Profile at the top of the page. In the pop up window you will find your inputted data, including name, username, password, and email address. Make the changes needed and save.
If an error message appears when you are attempting to save your new username, the username is probably already in use. Simply use an alternative, such as adding a 1 at the end of the requested username, until you find one that is not in use.
