I just want to say, this system sucks.
After several attempts, believing that I lost my mind, I had to "re-install" (and juggle) Opera so the "passphrase" would take my old password as correct.
And not being able to contact anyone from Opera with a system like this..... is nonsense. Not to mention that I doubt that linking it to the OS is a great idea.
In short, you have to know your last password yes and yes, and there is no information or "warning", saying "don't think that 'reset password' will help you".
