1Password was founded in 2005 by two friends, David Teare and Roustem Karimov. They built version 0.1 after they struggled to find a way to share passwords while designing websites. They soon realized this was something the world needed. Today, 1Password combines industry-leading security and award-winning design to be the most loved security tool on the market. Applications and extensions are available for Mac, iOS, Windows, Android, Linux, Chrome, Safari, Firefox, Brave, and Microsoft Edge.
