IRISPass is a free & open source software. It helps create and maintain secure, randomised passwords. It is cross platform and the binaries are available for MacOS / Windows / Linux / Android. It also supports password syncing across Desktop and Mobile devices.All the passwords which are either generated by the app or entered by the user are saved in devices storage. IRISPass does not possess a server and all of your data resides on devices that you own. The passwords are encrypted with your Master Password before it is saved in device. Hence, without the master password, one can not get access to your passwords. Thus, it is of utmost importance that the Master Password should NOT be easy to guess. IRISPass doesnt save your Master Password for security reasons, it will ask for it from time to time to ensure maximum security. Optionally, you can enable Biometric Authentication to avoid entering Master Password every time.IRISPass stores all your password data in the device itself. Syncing passwords is still possible even if your devices are not connected to any servers. The catch here is that the devices need to be in the same network. Syncing is possible between your Desktop & Mobile app. To sync passwords, youll need to click QR Code button from your Desktop app. Youll be able to see a QR Code on screen. From your mobile app, click the Sync button to open camera. Point your camera towards the QR Code and that should be it! To ensure that the passwords can not be stolen by someone else, IRISPass performs a "handshake" with your Email and Master Password. Hence, for password sync to work, the Email and Master Passwords should be the same both the devices
