Ok, so regarding this feature, it is good and bad.
This is going to break a ton of ranking services/management, games, etc. The thing is Roblox has not even announced the change or a notice which is annoying. This is going to cause major problems with ranking services as the ranking services will get a high amount of tickets. But this helps security as well.
I really suggest Roblox add a feature in Security allowing you to change it to bypass this change. However, you would need an Account Pin and a Verified Email linked to the account to do this.
Anyways, lets just hope for the best.
