I will burn your servers to the ground, foul villain - Star Trek: Website

Why does this happen though? I always wondered why is it that a platform recognises your old password only when you are trying to change it
If there were a data breach where a hacker could figure out the encryption algorithm, you don’t want users to reuse an older password because those older passwords could’ve already been cracked.
I understand when you are prompted to change, but not when you aren’t. As I mentioned in another comment I remember Epic basically trolling me into resetting my password almost daily at some point

There could be many reasons they don’t prompt you to change: they meant to send an email but your notification preferences disallowed it, they sent an email and you missed it, they wanted to keep it quiet, they forgot to add the message and ux flow to change password, or they’re incompetent and didn’t know they needed to do that.

The Epic thing I’ve never seen before but that’s definitely incompetence and/or a very weird edge case bug that just slipped past them.
