If you have lost your username and password, you can easily recover both by clicking “forgot password” on the login page and entering your email address. You will be asked whether you would like your password recovery message to be sent to your email address or mobile phone number.
For email recovery, you will need to click on the link in the email received and update your password. For SMS recovery, you will simply need to enter the password recovery code that was sent to your mobile phone. Please note that this will only work if you have registered with a valid email address.
