OK, it's not a big issue, but I didn't set any password to my wallet, now it's locked, and I have no idea which password to enter.
The first time you opened the wallet it gave you a password and told you to write it down. If you didn't grab it then, the only way to get it back is to stop siad, delete the wallet.json file, then start again.
You're not the only person who didn't get the password on the first try, we'll have to change it so that you can keep asking for the password until the first time you unlock the wallet (which requires the password). That at least guarantees that users realized there was a password before closing the window.
Hmm maybe I missed that, but I didn't seen any password that wallet should gave me, there was just some disclaimer about passwords.
And now, I deleted json wallet, killed siad process manually and this is all what wallet is saying, no password at all.
