Changing the account password

Hi,

Where's the feature/option to change the password or reset it with a random (and unique) generated one?

I would like to change mine but I can't find how.

Thank you!

Thanks for tip! I seem to have a problem involving my e-mail address (used for registraion). I've tried with all of them and I've
got this error: "Sorry, there is no user with e-mail address: ." There's no option (or I can't find it) after
logging in in order to view the associated e-mail address. I need help with that.

Not really a solution, since there will be 2 active accounts (and the original one will have the desired nickname, since they are
unique), and I'll need to mirror them manually.
