A strong passwords should have a significant length and cannot contain normal words. Only random digits and letters of different case. Such passwords are extremely hard to remember and it takes time to enter. But, even strong passwords have their weaknesses. When you type a password, it can be intercepted by a spy program that logs all your keystrokes. Others can see what you type (even if the password field on the screen is masked, the password can be read by buttons you hit on your keyboard.)
Until now, the only solution was to buy a secure token. A secure token is a hardware key that is used instead of or in addition to your normal password authentication. There are two main problems with the hardware solution, though. First, it is expensive. And second, you can use them only with software that has built-in support for this method of authentication.
But, from now on, you can turn any USB flash drive into a secure token! No need to purchase an additional expensive device. All you need is about 2 megabytes of free space on your flash drive or other USB gadget, such as an MP3 player, PDA or even a USB-pluggable mobile handset.
How does it work? The software, Double Password, installs onto your flash drive. When you type a password, the program intercepts it and converts it into a super-strong password string on-the-fly. You can use simple, easy-to-remember passwords without the risk of being cracked.
Another benefit of using Double Password is that nobody can steal your passwords. Spy programs are useless. Even if someone gets the "weak" password that you type on the keyboard, it means nothing. This password will only work when your USB flash is inserted.
While typical hardware locks will work only with software that supports secure tokens, Double Password works with any software. It simply substitutes your weak password with a strong one.
Double Password can be effectively used to securely lock your Windows account, to protect your laptop and to bring a new level of security to all software that uses password authentication.
