Requirements
1Password supports the following systems, web browsers, and applications.
Operating Systems
- Mac OS X 10.6 (Snow Leopard)
- Mac OS X 10.5 (Leopard)
- Mac OS X 10.4 (Tiger) support can be found in 1Password 2. See Using 1Password 2 on Tiger for details.
Supported Web Browsers and Applications
These browsers and applications are fully supported and have 1Password’s functionality integrated directly into them via our plugins:
The following browsers do not provide direct 1Password integration:
- Google Chrome: Support for this browser is being worked on, but you can get a little 1Password in Chrome now with the Logins Bookmarklet feature.
- Opera: Opera is a great browser and we would love to support it. Unfortunately, at this time, Opera does not provide the extension mechanism required for 1Password. In February, 2009, we again discussed this with Opera’s Mac developers and were informed that the necessary code changes cannot be made for the 10.x versions. We very much appreciate the interest in this collaboration and hope that we will be able to support Opera in the future.
- Netscape: Netscape officially dropped support for this browser as of March 1, 2008. Please try Firefox or Flock instead. Both are fully supported by 1Password.
- Internet Explorer: Microsoft officially dropped support for this browser as of December 31, 2005. Please try Safari instead.
- Shiira: The future of this browser is uncertain as of this writing, and no efforts are currently being made to add Shiira support to 1Password.
- Cruz (formerly “Mecca”): Support for this browser is being considered.
1Password for iPhone/iPod touch Requirements
1Password touch and 1Password touch Pro can be installed on any iPhone or iPod touch with iPhone OS 3.0+ and the App Store installed.
1Password for Palm Requirements
Palm handheld or Treo smartphone running Palm OS 4 or higher with 150KB of free space. Additional space is required for the 1Password database, which depends on the number of items you have. Each 1Password item requires about 3KB, so 1,000 1Password items will require approximately 3MB of space.
