Safety issues with numeric login and sudo passord
#1
I can’t be the only n00b PinePhone-owner who’s not too excited about how my ordinary user can sudo with the PinePhone’s lockscreen PIN-code? This is the case in both Manjaro and Mobian. If one should be the victim of a brute force password attack, even a 16-20 digit numerical password is cracked before you can blink, and the attacker can log in as root with it. Numerical password is also a lot easier to see (few, big buttons) and memorize in a «over the shoulder password attack» than be an alphanumerical one with upprcase, lowercase and special characters.

I have actual enemies skilled in «pentesting» (cracking) who have subjected every aspect of my digital life to targeted attacks, often successfully, so my need for device security probably exceeds the average internet surfer, but even the typical average user with no personal enemies could get hurt by crackers who have the knowledge of this numerical password issue on Mobian and Manjaro. 

I’ve tried several guides found online, for setting privileges and demanding root passwd for sudo, but there aren’t as many n00bs posting these stupid questions about Mobian or ManjaroARM as there are people answering these questions about desktop Ubuntu. Please help! How to fix this on different distros respectively? Removing sudo privileges will permanently lock you out of root on Mobian because the only way to log in as root is sudo -i with the lockscreen PIN code, while on ManjaroARM that might be a solution. Please help!
