Remove two-factor authentication warning

Open iCloud Preferences and click Continue. Decline to the request to enable 2FA by selecting "Not Now". That will make it go away.

I tried this, I didn't get the option to decline. I got "Cancel" or "Continue". The latter asked me to enter my iCloud password, and then nothing else. I don't know if I've inadvertently turned it on or if it's just going to go away, now.

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. A new post would be much more visible. You can link to this one.

What happens when you try what John suggested?

I have the same problem, it just started a few days ago on its own.. Both on my iPhone and iPad, I select not now and an hour later it is back. So annoying. Apple support said do not turn it on as it only causes problems like locking you out of your apple products, some people even lose everything because of it and have to create a whole new apple ID.. I am guessing this is another attempt of Apple to force people to think they need new hardware, they already cause older, like 5 years older, apple products to run dirt slow. There is no doubt this is intentional, thus guaranteeing I will not stay with apple in the future when I do decide to upgrade hardware. Did you ever find a solution to this annoying two factor popup problem?

If you own a mac that is new enough to have the feature too (don't ask me which ones, I only own a 2008 macbook that apple is prohibiting me from updating..) you could try this one I found online and seemed to work for people there.

Find the 2-factor authentication setting -> press turn on -> press cancel

that should make it go away, tried it on my ipad but to no avail..

Wrong John, This does NOT solve the problem that Apple created.

I have the same problem. What happens is that it goes away for a very very short time then comes back.

Where on iphone 6 do I find icloud preferences and Continue????

Thank you
