Microsoft Edge loads all your saved passwords into memory in cleartext — even when you’re not using them; Microsoft will not fix, says the behavior is "by design" - Lemmy.World
Hacker News [https://news.ycombinator.com/item?id=48012735]. > When you save passwords in Edge, the browser decrypts every credential at startup and keeps them resident in process memory.

This is why I close every Edge process at least two or three times per day!
