Your username is the email address your account was registered with. Typically, this is the same address as your work email.
If you have forgotten your password, you can tap the FORGOT YOUR PASSWORD? link on the LOG IN screen of the app (or click here) and enter your username. You will be emailed a temporary password. Once you receive the email with the temporary password, log in with that password. You will be prompted to create a new password once you log in.
