Simply secure.

Strongbox exists because of a need. Now, we're sharing it with the world.

Strongbox began as a simple side project because there were no password managers on iOS that supported the famous Password Safe file format. This was something I personally used in my work day to day and regularly for my own personal passwords. Back in those days Password Safe was one of the leading password managers for Windows and was initially created and supported by world famous cryptographer Bruce Schneier.

As the world became more mobile and as desktop Windows lost its dominance the need for an Open Source password manager only grew and this is when my own need for a Password Safe client for other platforms grew. Strongbox emerged from this need and has grown and developed into what you see today. Originally built as a home project just for my own use, many others found it on the App Store have found it useful which has both really surprised me and brings me great joy.

Support for KeePass was added in late 2018 due to many requests and its popularity has increased with this extra functionality. The KeePass format adds many nice features such as custom fields, attachments and icons as well as strong cross platform support and a larger community than the original Password Safe format.

Strongbox is nearly five years old now and has many more users than I could have ever imagined. Strongbox is a work in progress as is all software but if you like it, or have any questions or comments, feel free to get in touch ( . I’d love to hear about how you or your company are using Strongbox.
