1. In the log-on screen, click 'forgot your password', and input your email. 2. Then you will find a link in your email, click it, you will reset your password. The way is not in need of your original password. Or your original password will be sent to you indeed. (I do not know which way this site uses.)

It is easy. go to settings and change your password

My italki acc. is connected on may facebook that's why I still log on. Im not playing . But I want to deactivate this acc. but I forgot the password , the password on my italki not on my fb acc. and I can't deactivate this so I'll just not use this italki though.

?????? How did you log on? I think you are playing a weird joke
