I would like an option to disable PIN, similar to the existing option to disable PIC. There are accounts where people don't really care as much about their security, such as mages and mules - you don't hold any major meso on those. I don't find it reasonable to enter 6 pins on my mages everytime I go to farm, I just find myself sitting there for 2-3 minutes entering pins which is a major annoyance. Same goes for cr/sed/se or etc storage mules.
Interesting, I only have to enter my pin whenever I'm connecting from a new IP. Is your IP changing a lot?
I have dynamic IP, and also I use mobile data a lot, where the IP is reset everytime I go into flight mode/different area or get a call, so yes.
Dynamic ips are not as common but I strongly agree with your point, it can be frustrating at times. This would be a cool feature as long as you can disable only one at a time, either pin or pic. Allowing to disable all securities except for password will invite a lot of problems that are unnecessary, you will do it on an account with no value inside, but not everyone.
https://royals.ms/forum/threads/account-security-a-reminder.207236/ the overall consensus is that the pros doesn’t justify the cons in this case. Although I understand your point of conveniency, we cannot offer it in the cost of account security
