1Password

1Password is a secure password manager* that goes beyond simple password storage. The extension integrates directly with your web browser to automatically log you into websites, enter credit card information, fill registration forms, and it can easily generate strong passwords.

The 1Password extension for Google's Chrome browser is simple to use with a unique interface. One click opens your browser, opens a website, fills in your username and password, and logs you in. With the 1Password extension installed, you can use a single click to create strong, unique new passwords for all your accounts, then it remembers them in the 1Password vault so you don't have to.

Key features include:

1Password uses the best available encryption from well-trusted and scrutinized cryptographic libraries.
You only need to remember one single password for all your accounts.
Browser integration.
*This extension requires 1Password 4 for Mac or Windows, sold separately and available from the developer, Agilebits.
