F-Secure KEY stores your passwords on the computer or mobile device you use to run the KEY app. Your passwords are stored in encrypted format and nobody can access them unless they know your master password and get access to your device.
When you upgrade to the KEY Premium version, you can sync your passwords across your devices. For security reasons, we do not provide access to the passwords through F-Secure servers. We recommend that you sync your passwords with another device running the KEY app, just in case you lose or break your device. No matter what happens to one of your devices, sync ensures that you will always have access to your passwords on the other devices.
