I've tried multiple ways, but still I couldn't figure out how to do it. It would be helpful if you added a tutorial on the topic.
The vault takes the phone password by default, and that's that.
When I'm inside, I can add photos and folders, but I don't know how I could add different passwords to different folders, and is there a way to use a different password for the master password of the vault rather than the phone's default password? Help needed.
