Passwords

Software to safely keep passwords is available in several formats, including those for desktops, portable devises, and versions that store your information and make it available via the Web. Some products are commercial, and others are freely available, with a subset of those being open source.
In addition to encryption and other features that address security issues, password management software may also fill in forms automatically, allow users to organize passwords into categories and subcategories, generate random passwords, and other useful tasks.
Common Web browsers offer help with remembering passwords, and although many people make use of this feature, encryption experts express concerns about security of these systems.
