Platform
[I dont personally use it but it could have the feature too] iOS
[✓] Android
Obsidian Mobile Version: v1.0.4
TDLR;Add the option to enable a pin/password that must be entered before you can use the rest of the app
Backstory: Half the reason I use Obsidian is for diary writing, and it would be amazing to not have the dread that my brother could just snatch my phone and read everything
Related Post: there was another post similar to this, but im suggesting just a pin/password feature, while the other post suggests 2fa[which could be added too, for those who need more security]
Weakpoint ?: As for the fact that theres not much point since the files are in the system-the file explorer i use is password protected[ofc a computer could be connected to see the files(in my case my brother wouldnt do ALL of that so just a pin/password would be good enough)]
