In case, you type the wrong password, you could not log in.

Click "Forget your ID and password"

Next, you will fill your info to fill in the form and then click "Request Password Now"

Ok now, your User name and new password have been sent to your email. Please check email.

One more thing, the system will send you a random password, but if you don't like it, you can change as you want. Go to your account/settings to change your password.

Good luck to you!
