Troubleshooting iCloud authentication error on your iPhone 11 Pro
Errors affecting Apple services like iCloud may be due to unexpected server downtimes as well as scheduled server maintenance. To check if the iCloud server is up, go to the Apple Support status page and see the current status of the iCloud server. If the status indicator is green, it means that the server is up and available. Otherwise, it’s currently having some issues and thus unavailable. If it’s the latter, there’s not much can be done on your end because the problem is with the Apple server. Thus, you’ve got no choice but to wait and try using iCloud at some other time, probably after an hour or so. If the service is up but you’re still getting an iCloud authentication error when trying to use iCloud on your new iPhone, you can try any of the following solutions to eliminate possible causes.
First solution: Log into your iCloud account again.
If you get an authentication failed or similar error when attempting to sign into your iCloud account for the first time, then most likely you’ve entered the incorrect credentials. In this case, you may have to consider logging in again by entering the correct Apple ID and password. Although you’ve thought that you entered the correct credentials, you might have mistaken and thus result in iCloud authentication error or login failure. To clear this out, follow these steps to redo the sign in process to your iCloud account:
- Open your browser app then enter appleid.apple.com in the address bar. Doing so will route you to Apple’s sign in page.
- Enter the correct Apple ID or iCloud credentials on the given text field.
- Click the Arrow Right button to continue signing in using the credentials you entered.
You can also reset your password using the provided password reset link (Forgot Apple ID or password) in case you aren’t if you entered the correct password for your Apple ID.
Alternatively, you can sign out of your iCloud account straight from your iphone 11 Pro settings with these steps:
- From the Home screen, tap Settings.
- Select your Apple ID label.
- Scroll down to the bottom of the screen then tap Sign Out. Doing so will log you out from your Apple ID/iCloud, iTunes & App Store accounts.
- Enter your Apple ID password and tap Turn Off to continue.
- You may choose to turn on the data that you’d like to keep a copy on your device.
- Then tap Sign Out twice to confirm that you want to sign out of iCloud.
Reboot your iPhone after successfully signing out of your iCloud account and then continue with these steps to sign in again:
- Go to the Home screen then tap Settings.
- Tap the option to Sign In to your iPhone.
- Enter your Apple ID and password.
- If you’ve set up your account with two-factor authentication, enter the six-digit verification code sent to your specified device.
Then follow the rest of the onscreen instructions to complete the sign in process.
Second solution: Reboot or soft reset your iPhone 11 Pro.
If you were able to use iCloud services on your iPhone before and suddenly you’re seeing an authentication error, it could be due to some random system errors transpiring on your device. To eliminate these random flaws, simply reboot or soft reset your iPhone with these steps:
- Simultaneously press and hold the Side and Volume Up buttons for a few seconds.
- Release both buttons when the Slide to Power off bar appears.
- Swipe or drag the bar to turn your device off.
- After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.
In the case where your iPhone display seems to get stuck on the authentication error, performing a forced restart would be necessary. This method is used to restart an unresponsive or frozen iPhone. It works the same as a soft reset when it comes to rectifying minor software errors without inflicting permanent data loss. Just follow these steps if you need to force restart your iPhone 11 Pro:
- Quick-press then release the Volume Up button.
- Quick-press then release the Volume Down button.
- Finally, press and hold the Side button until the Apple logo appears.
You can release the Side button when you see the Apple logo and then wait for your phone to finish its boot sequence.
Third solution: Refresh your internet connection.
Random internet connectivity issues can also trigger similar errors to occur when using iCloud services on your device. This is usually the case if your phone is experiencing slow internet connection, intermittent or no connection at all. Should this be just a minor issue, refreshing the internet connection on your phone can help. There are various ways to get this done. And the simplest ways are as follows:
- Toggle Wi-Fi off and on. Turning the Wi-Fi switch on your iPhone can also help resolve minor issues affecting wireless functions and online applications. Doing so gives a quick refresh to your phone’s Wi-Fi system and thereby eliminates any existing connection errors Here’s how it’s done:
- Tap Settings from your Home screen.
- Select Wi-Fi.
- Tap the Wi-Fi switch to the OFF position.
- After about 30 seconds, tap the switch again to turn Wi-Fi back ON.
- Wait for your iPhone to reconnect to your Wi-Fi network and then try launching Messenger again to see if the problem is gone.
- Perform the Airplane Mode trick. Another simple old trick that’s been used to rectify various wireless connectivity issues that caused online apps to crash or stop working on an iPhone is the so-called Airplane Mode trick. It works by giving a simultaneous restart on your phone’s wireless features. Here’s how it’s exactly done:
- Tap Settings from your Home screen.
- Select Airplane Mode.
- Tap the switch to turn Airplane Mode on. Doing so simultaneously disables wireless radios of your iPhone.
- While Airplane mode is turned on, restart/soft reset your iPhone.
- Then head back to Settings-> Airplane Mode menu.
- Toggle the switch to turn Airplane Mode off again.
Wait for your iPhone to re-establish wireless signals. Once it’s back online, retry using iCloud and see if the error is gone.
Fourth solution: Install new iOS update to fix iCloud authentication error on your iPhone 11 Pro.
If there’s no problem with your internet connection, then try to check for available firmware updates on your device. Installing these updates can also be the key to resolving existing errors on your phone, including iCloud authentication and relevant errors. Here’s how to check for OTA updates on your iPhone 11 Pro:
- Open the Settings app from your Home screen.
- Select General.
- Tap Software Update.
You will see an update notification if a new iOS version is available. Read and review the information then follow the given instructions to download and install the update on your iPhone.
Fifth solution: Reset network settings on your iPhone.
To eliminate all network-related issues that might have caused problems to iCloud services, resetting the network settings on your iPhone 11 Pro can be considered among the last options. Through this reset, you can erase any invalid network configurations along with the associated errors. This will not affect any saved data on the internal memory, so you won’t be losing any single data. However, all saved connections on your iPhone such as Wi-Fi networks, Bluetooth devices, cellular settings, and network customization will be deleted. If you wish to proceed, then you may through these steps:
- From the Home screen, tap on Settings.
- Select General.
- Scroll down and tap on Reset.
- Tap Reset Network Settings from the given options.
- Enter your passcode if prompted to continue.

Last resort: Erase your iPhone and set it up as new (factory reset).
If you’re iPhone 11 Pro is still prompting the same iCloud authentication error after applying all prior methods, there’s a great chance that you’re dealing with a complex system error. This therefore denotes the need for you to carry out more advanced solutions. Among the last options you’ve got (if you wish to troubleshoot further) is a factory reset. This will erase everything from your iPhone and then restores its factory default settings. Doing so will allow you to set up everything including iCloud account on your iPhone as new. But before you proceed, be sure to back up all your important files saved on the phone storage so you’d still be able to restore and use them again later. Then you may proceed with a factory reset through these steps when ready:
- From the Home screen, tap Settings.
- Tap General from the given options.
- Scroll down to the bottom of the screen then tap on Reset.
- Select the option to Erase All Content and Settings.
- If prompted with a warning message, tap on Erase iPhone to proceed.
- Enter your passcode to continue.
- Tap Erase iPhone twice to confirm.
Your iPhone will reboot by itself when the factory reset is finished. When it reboots, all its factory default settings are restored. To use your phone again, you will need to set it up as new. Just use the start-up wizard to set up your iPhone automatically.
