By Kerby, 14 December, 2017 Forum iOS and iPadOS I want to turn off two factor authentication but can't seem to do so on my iPhone. When I double-tap the toggle button it still says on. Is this something that has to be turned off in iTunes or something? Thanks. Options Log in or register to post comments Comments 2FA I went to https://appleid.apple.com and turned it off in there. I never did try from my iPhone. On phone or computer, website must be used Two-factor authentication can be turned off from your iPhone, but not with a toggle: you have to sign in to do it, on the Apple ID website mentioned above. I turned two-factor authentication off using Safari on my iPhone, but it can also be done on any browser on the Mac or PC. Thanks That worked. Thank you all.
