There is no free version of 1Password. RoboForm Free lets you store an unlimited number of Logins locally on a single device.
Need or want to use Internet Explorer as your browser? 1Password discontinued support for IE, forcing users to copy and paste their credentials into the browser. RoboForm, however, supports all major browsers including IE and Edge.
Unlike 1Password, RoboForm lets you bookmark your favorite sites for quick and easy access across all of your browsers and devices.
RoboForm Everywhere does it with ease. 1Password forces you to create a separate Vault in order to share items with others.
While 1Passwords limits saved Logins to websites, RoboForm lets you save your Windows application passwords too.
RoboForm gives you more options for support than 1Password. In addition to our 24/7 online support system, you can send us a Facebook message, chat in, or request a callback. We're here to help!
