So I entered my nsec into badges.page… then I realized and learned that I shouldn’t be putting my nsec into websites without using an extension. So now I have Nostore, but can anyone explain how badges.page stores my nsec and how problematic this was?

Also, like in centralized platforms, is there any way to update or change your nsec in order to remain secure while maintaining the same profile? Is there any thoughts on how this might be managed now or in the future?
