Lock & Unlock with FaceID & Safe mode

Logseq is basically my second brain. I hope the app can be protected by password & FaceID so my graph is safe even if my phone is unlocked. On PC&Mac, I hope the data to be in some encrypted format instead of plain text. This is not quite possible since the graph is based on .md files at the moment. But I hope the safety&encryption needs can be considered in DB mode.
