Request: App for decoy password on lock screen

[sreehax]

This is just a question. Is there any way that i can set up a decoy password on my nexus 5 lockscreen? I am rooted and running LineageOS 14.1 and the phone passes SafetyNet, and has internal storage encrypted. Here's an example: your real pin is 13579, but you want a decoy pin (24680). When 13579 (real pin) is entered, the phone will unlock like normal. But, if 24680 (decoy) is entered, then the phone should switch to a different (possibly restricted) user, so that if you are stopped at an airport and your phone is confiscated and the authorities ask for your pin, you can give them the decoy. The switching users should be invisible, so that the authorities don't suspect anything. If they ask about the main user, i can just make up an excuse like "This is my friend's phone, and i am going to visit him. He just added me as a restricted user". Note: i just want to keep my privacy and make sure that my data is safe.
