it also leaks the audio of tabs before logging in.

Even though I had disabled all 'restore' applications features, macos sometimes decides to 'start' browsers BEFORE logging in after a restart AND those start auto-playing audio from whatever was paused before the reboot (or many days before).

Since then I went rather deep disabling that feature, but I never trusted it.

I have never heard of anyone with this issue.

The only explanation is that you restarted whilst having the "Open All Previous Application" checkbox enabled. And yes it will launch processes after you have logged in but before the Desktop is shown.

Either that you or you have some launch daemon that is opening a browser.

I’m very confident that it’s either this or the restore-after-crash feature that OP is seeing. I don’t think it’s anything specific to Safari, because I have never seen Safari opened before login when it’s not my default browser.

That said, there should probably be a checkbox in system settings to disable login “prewarming”.

I actually used Chrome and Edge. Both show that problem. But the main issue is not those browser autoplaying audio and video on "restore", even though it is an issue, its the OS thinking its OK to load apps before a user authenticated itself after boot
