(Opera and Vivaldi may be able to use one or both of the Chrome extensions.) There are also command-line 1Password interfaces for Windows, Linux and macOS/Darwin and Darwin's cousins FreeBSD and OpenBSD. The 'old' browser extension is available for Brave, Chrome, Edge, Firefox, and Safari. In May 2021, the 1Password Linux desktop app was officially released, after several months in beta testing, and supports most major Linux distributions.ġPassword in the Browser, formerly known as 1Password X, the full-featured 'new' browser extension, supports Linux and Chrome OS as long as you are using Brave, Google Chrome or Mozilla Firefox, and it supports those browsers on Windows and Mac as well as Edge on Windows and Safari on Mac. For macOS, you will need 10.13 High Sierra or later. To sync the standalone desktop app's data with the mobile 1Password apps, you need to make a one-time in-app purchase of $9.99 in the iOS and/or Android app to unlock the Pro features.ġPassword supports Windows 10 and above along with Microsoft.
