How It Began

When Roustem and Dave founded 1Password in 2005, they were trying to solve a simple problem. They were developing a lot of websites, and filling out forms to test them was time-consuming. They started a one-month passion project so they could get their work done more quickly. They thought others might enjoy this as well, so on May 19, 2006, they uploaded the first version of “1Passwd” to MacUpdate and VersionTracker. They were surprised by how many people loved it. Folks immediately began providing feedback, which was incorporated into a lot of new releases, this led to more feedback which led to more late-night coding sessions. And so began the incredible virtuous cycle.
