This cannot be set separately. The password of the software lock is the password of the private space, so if you need to set two separate passwords, whether it is encryption software or entering the password of the private space, it is suggested that you can download the third-party encryption software and try it, or you can turn on the guest mode in Settings-More Settings-Security of the mobile phone. In this mode, the address book, SMS, call history and gallery of the selected contact will be hidden. If you want to exit the guest mode, just lock the phone screen and enter the screen lock password to unlock it.
