Today I switched to my "Second space" and thought about sharing it.
My Android phone has a security feature called "Second space", the name and functionality might change based on what device you have.
This feature create a secondary profile on your device that you can switch to with either a second pin / password or a dedicated fingerprint (still, a pin / password is required).
Imagine having you phone inspected by authorities, you can unlock the main profile and show them without any immediate trace of it (except if they look for the "Second space" feature, which is still pin / password protected).
Of course you can quickly switch to it by maybe swiping your little finger or even a foot's fingerprint and be ready to access your more secure apps like wallets, social clients or any other sensitive or personal application.
Some might even install decoy apps on the main profile to have something to show in case it's needed.
I hope this hint you at looking for unknown features your devices might have that could help you keep your personal life a bit more private.
Cheers! 👋
