Advanced PassGen is a free application to generate passwords. The tool allows you to create passwords according to your preferences. Advanced PassGen allows you not only to specify the length of the password, but also to decide whether it should contain only numbers, or consist of letters (lowercase or uppercase) or special characters.

Interestingly, you can generate more than one password at a time. Passwords created with Advanced PassGen can be exported to a file saved in TXT, HTML or CSV format.
