The master password is very important as it gives you access to the app and keeps your password data safe.
Once you’ve installed F-Secure ID PROTECTION and you start the application for the first time, the app asks you to create a master password. The master password is the only password that you need to remember once you have taken ID PROTECTION into use.
Choose a hard-to-guess master password or passphrase that you can remember, as the app will not able to reset your master password if you forget it. The fact that there is no way to reset a forgotten master password has been a conscious decision by F-Secure to increase your security and privacy, and to protect your data.
The recovery code is the only way of regaining access to the app, should you forget your master password.
