weisoq, maybe your browser deletes cookies after every visit? That might explain what happens. You have an option of storing the wallet in the browser and/or on Payward.

Some people are confused about exactly where their wallet resides, it seems. Personally, I keep it in my browser, and I've also backed it up as a file on my harddrive, and I've stored the secret key as well.
To lose your wallet even with your login information, you need to
- fail to use a blob store like Payward
- fail to back up the wallet file
- fail to take note of the secret rescue key
- lose your browser cookies

If all those things happen, you have lost your Ripple wallet. If you averted one of the above, you can get back into your wallet. Correct?
