A password to your files is nothing if you don't hold the keys to your data.
Sure, your password helps protect your account from being accessed by someone you share your computer with. But if you don't hold the keys that were generated when you created your account, your password can only do so much to protect your privacy.
To put it in context, SpiderOak Engineer Tomás Touceda describes it as "going out the front door of your house, locking it really well and leaving the key in a handy hook right beside the door."
No matter how many privacy and encryption features are offered by other companies, you should always ask yourself "who holds my keys?" When you create an account with SpiderOak, you are the sole owner of your keys that encrypt your data. Thus we have Zero Knowledge of what you're storing with us.
