After you set a secret code, you may opt to protect access with a fingerprint. Kaspersky app uses the same fingerprints you add in your device settings. So, if you haven't used fingerprint scanning before, you will be redirected to your device settings.
To use fingerprints to protect access to Kaspersky app settings and features, select the Unlock with fingerprint check box in the setup wizard or in Settings > Screen lock.
