I used shape shift to convert bitcoin to ether and received ether in my wallet. I am trying to send it back to shape shift and it is asking me for a password. I don't remember ever setting up a password. I thought there were default accounts in the wallet. Did I just lose a bunch of money?
The wallet prompts for a password when you create the account. Did you try passwords that you commonly use? You can attempt to brute-force it using a file of passwords that might work using https://github.com/ryepdx/pyethrecover
