1Password is an online password management service developed by the Canadian company AgileBits Inc., based in Toronto. The application allows users to store their passwords, software licenses, and other sensitive information in an encrypted data vault, secured by a PBKDF2-driven master password (hence the name), and maintained and synchronized on the company's server for a monthly fee (web hosting). The data vault can be integrated into the browser via a plugin and accessed through a mobile app or as a web application in the browser.
