iPhone 16 w/IOS 18 -can’t log into some apps

I’ve seen it with 2 apps so far -American Airlines & Yahoo Fantasy—the issue is when selecting Log In on each app-it then opens up the safari webpage to log in -at that point I’m unable to type anywhere, no keyboard opens up , nothing.


It appears that this issue happens with apps that kick you to a safari website to log in vs apps which you sign in on the actual app if that makes sense.

iPhone 16, iOS 18

I’m having the same exact issue, and it doesn’t have anything to do with VPN settings. Does anyone else have any insight to fix this? I’ve tried every kind of troubleshooting method I know how.

iPhone 16 w/IOS 18 -can’t log into some apps


One million thank you's sir!!!!

I have been plagued with this anomaly for 9 days now. I have posted on Apple Developer and Microsoft forums and called Microsoft tech support about this horrible issue. I could not install the Microsoft Authenticator or login to anything related to Microsoft on my new iPhone 16 Pro running iOS 18.


Your suggestion/tip below worked like a charm!!!! THANK YOU!


To elaborate a little, as to my specific experience;


Settings > General > scroll down to VPN & Device Management [select]. > VPN [select]. > simply turning off VPN Status will auto reconnect and turn VPN back on. > Select ExpressVPN Lightway [CLICK ON the blue I ] > TURN OFF Connect on demand.


BAM...after 8 days of sheer frustration my Microsoft Authenticator installed perfectly. Prior to this fix I had cleared my browser cache, uninstalled all Microsoft Apps including the Authenticator and Edge. Always upon reinstalling the Authenticator when trying to login I kept getting "Too Many Requests" !!!!


The above solution worked perfectly! thanks for the tip Lawrence! Credit where credit is due.

I am having the same issue and I don’t see Apple resolving this very major bug a month after the release of iPhone 16 …. Wtf ?

As you are having the same issue, it would be logical to read the rest of the messages in the thread you posted to. AFTER you do that, if you don’t find the solution there, post back with what you tried.


BTW, there is no major bug. If there was you would see 10,000 posts about it. There is a problem with your phone hardware, your software configuration, or some junk apps you installed on your iPhone.


And if you have the SAME issue, that is, American Airlines and Yahoo Fantasy, you need to contact those app developers; it has nothing to do with Apple.

I have a new iphone16 and have been fighting with it all day! I read all the questions and answers, and voila - I was able to sign in to Facebook!!! I had a McAfee VPN in the Settings/General/VPS & Device Management, and was able to delete that VPN!! Now I'm back on Facebook on my new phone! Thank you all for your suggestions and assistance! I was going nuts trying to figure it out!!

Do you have an app that tries to log in with a general web browser like Safari? Have an app that gives you a blank login screen with no boxes to fill in? If you've already tried fiddling with VPN and other settings, try this solution instead. I've had this problem for a long time with some apps, including Wyndham Hotels and American Airlines. This solution fixed it for both apps:


First, swipe away the app button. Then go to the Safari app on your iPhone and log in to the desired site using Safari. You may then see a prompt appear at the top of the Safari screen asking you to view the desired site in the real app. Try doing that; it should enable the problematic app to store your login information on future launches.


If not:


While still logged in to the Safari app, try pressing the desired app's actual button on your iPhone (NOT the Safari prompt this time). The app may then be able to retrieve and retain your login information using Safari's running session, enabling it to log in by itself without assistance thereafter.


I hope this works for you all too. ❤️

This happened to me with Facebook and Instagram on new iPhone 16. I couldn't log in to either.

It wasn't the VPN.

I got into Instagram by 'authorising' the log in via my iPad (lucky I had one because the notification did not go to my Mac laptop).

I got into Facebook by using "try another way" option, which allowed the code to be emailed (Instagram did not have the email option).

Having similar issue as the people

in the replies.(16 pro max, iOS18.2) select apps won’t let me log in. Tried various solutions relative to the accounts themself, and can log into these accounts fine when using safari or chrome on my Mac book. It’s not VPN, I tried that solution, don’t use an active vpn anyways. I tried disabling screen time but to no avail. Tried the typical restart and re download, also went through settings to see if anything could potentially limited access (location services, authorizations, etc)

Well, that’s likely the problem if you DID have VPN on a device you transferred from.


An important and frequently overlooked fact is that when you install VPN it configures itself to the specific hardware, OS version and network that the device uses. If any of those change it can break the VPN. So any time you change any of these you may need to delete the VPN app and profile, restart your device, then add them back (if you still want to use VPN) so it can configure itself to the new environment.

Here's more detail about: VPN - What you need to know
