If you have forgotten your login email address, you can reset the password to check if your email address is registered with a Yu ID.
Enter an email address you might have used and your date of birth on the password reset screen, and press the [Send] button.
If the entered email address is registered with a Yu ID, and if the date of birth matches, the following figure will be displayed, and the password reset email will be sent to that email address.
