Walletx is a useful application that lets you save passwords, user account information, credit card numbers, bank accounts, and other important data under strict security measures.
The application helps you keep all your passwords and other information at hand, just in case. You can also sync it with Dropbox.
It's really easy to use. You can save all your passwords by using a master password, so you only have to remember one. After you insert this password, you have access to all the others you've saved to the program.
Forget about remembering every single one of the passwords you use on your social networks and other websites.
