This has nothing to do with being logged into TikTok. This is a link within the TikTok app keylogging credentials as they are entered.

And for the record, “logged in” isn’t the same as “identified”. Browser and device fingerprinting is very much a thing, and is quite scary in how well it works.

If you don’t think TikTok has CDNs (or that CDNs are used primarily for tracking?), it makes it clear you don’t actually know what you’re talking about.

It’s clear you either don’t know, or are being disingenuous about, the dangers of a bad actor in current technology. Especially when most of your argument is “you don’t even need to log in, it’s just so safe!”
