I am looking for a guide to use this bitcoin wallet
http://bitcoin.org/en/download .
I never made any password or username, I just ran the program and it worked without no login.
I rechieved money on it, but I wonder why it does not ask me for any username or pass when i start the program, even after i reboot my computer.
It automaticly signs me in to my account when started. Will that say that I can only get to my wallet by using this program on this excact computer?
I also chose to encrypt my wallet, and now I cant find any way to decrypt it again.
As mentioned above, a guide to this kind of wallet is much appriciated.
