As in, I have yet to find a good tutorial here.

I do agree with most of what https://forums.androidcentral.com/samsung-galaxy-s5/391717-trusted-credentials-what-happens-if-they-all-erased.html kicked around but in each case we would have to research each credential (but how?) and then test to see what each breaks.

In some cases it will break logins, face recog and fingerprint logins. You'll have to be ready to do a factory reset to get back in.

I know to google each but since the amount of work I would have to do, I just don't.
