Hello.
Please explain me how can I totally delete pattern to unlock screen. I’m talking about Protected apps section.
What I see I can set a new patter, but I can’t delete it.
Cheers
Regain your privacy! Adopt /e/ the unGoogled mobile OS and online services
If you are referring to the screen unlock pattern to remove the pattern
Settings >> Security & location >> Screen lock >> Confirm your pattern (here you will have to input current pattern ) >> Choose screen lock - here choose none
This should remove the screen lock pattern.
I’m referring to Privacy -> Protected Apps
I guess it can be deleted by deleting a particular file thanks to the TWRP’s file manager (like for the screen lock PIN/password) but I don’t know which file and where.
If that’s true. I’d say it’s a bug or thing to improve. What I understand eOS has been designed for common user and dealing with TWRP is rather part of at least kind of advanced one.
Where do you see this setting ? If I type privacy under setting all I see are these options but do not get Protected Apps under any of them.
It’s exactly Settings → Privacy → Protected apps
BTW: I don’t know why in English language, there is section available in Polish. Prywatność means Privacy 
Yes, it’s Android 7.1.2
I tried now, and I also tried a few months ago, and I remember that I could not permanently remove the pattern for that function of the Privacy Guard.
The only way was to reset
Okay, I guess it’s time to open a bug regarding this issue.
(Off topic) So, if I didn’t activated Secure Startup, and only had the pin, that would mean that anyone accessing the twrp could delete a system file and then cancel the pin, right?
What I know, if anyone accesses your phone via TWRP it has a root access to it, so if he/she is power user they can do anything with your phone.
Maybe phone encryption might set some security to your at least private data…
Yes, you’re right, I didn’t know!!! 
I tried and I remove pin by deleting only one file!

So, the only way to secure is:
encrypted disk, pin + secure startup.
I will do it!
Thanks and bye
It’s simple : if your phone isn’t encrypted AND/OR is without any pattern/PIN/password, then anybody could go into TWRP and access every file on the phone.
