Hi,
magento 1.7 requires mcrypt extension. Ask your hosting provider to enable it.

If that doesn't work check the solution given here http://www.magentocommerce.com/boards/viewthread/286198/#t416869

If you are using any username and password saving application in your browser it could cause this issue.
