If the Avira Password Manager app is installed on your mobile phone, you can bypass the password reset, and unlock the app with the Face or Touch ID on your device. Once your app is unlocked go to Settings and change the master password. This way you will not lose any data stored in Password Manager.
In case you cannot make use of the upper described workaround, you have to reset your master password via the Password Manager dashboard.
