“An unexpected error occurred. Please try logging in again”, ”There is an error in logging you into this application,” and “Login problem security check” are just a few of the many error prompts anyone may encounter when logging into social media networks and online messaging platforms like Messenger and Facebook app. 

If any of these error messages or a similar error prompt is bugging you when attempting to login to Messenger on your Apple iPhone 13 mini, then you can try the outlined solutions below.

What causes iOS Messenger Login error in Apple devices?

Messenger is by far one of the most popular and widely used online messaging platforms worldwide. With over a billion users, it’s safe to say that Messenger is indeed reliable. However, such popularity is not a guarantee that Messenger users wouldn’t be facing any sort of dilemma. 

It turns out that just like other apps, Messenger also succumbs to random glitches from time to time. This is on top of the unexpected technical difficulties transpiring on the server and regular system maintenance conducted in the backend.

Emerging among the common problems that many iPhone users faced with the Facebook Messenger app is login errors. This is when access to the Messenger account and the app itself seems to be barred.

There are many possible reasons as to why the Messenger app doesn’t work and logging into the app is not successful. 

The most obvious reason is incorrect login credentials like entering an invalid or incorrect username and/or password. 

Login errors can also be triggered by some errant app cache, faulty updates, random bugs and malware. 

In some cases, unexpected and scheduled server downtime is found to be the underlying cause of the problem. Apparently, server-based apps and other online platforms are typically not accessible when the main server is down (server outage). The same thing can happen if critical app data or the app itself gets corrupted.

Generally, the underlying cause is software-related, and therefore fixable by end-users.

In case you would bump into a similar issue with the iOS Messenger app on your new iPhone 13 mini, I’ve mapped out a few helpful tweaks that can help eliminate common culprits..

Troubleshooting Messenger Login Error on iPhone 13 mini

The subsequent easy fixes are also applicable when troubleshooting login errors with Messenger on other iOS devices that are running on the same platform or iOS version with the iPhone 13 series.

Actual screens and menu items may vary between device models and wireless service providers.


  • Before you begin, verify and ensure that your iPhone is running on the latest iOS version. If there are any pending iOS updates that you’ve missed to implement, then you better update your iPhone first.
  • Also make sure that the date and time settings on your iPhone are correct. Some login errors are likewise attributed to invalid system date and time.
  • If Screen Time is enabled on your iPhone, make sure that the Messenger app is not restricted.

Don’t forget to test login to your Messenger account after performing each solution to determine whether or not the problem is solved. Proceed to the next applicable solution(s) if needed.

Solution #1: End then relaunch the Messenger app.

Sometimes, login errors are just transpiring as a random in-app glitch which are often addressed by an app restart. This is the simplest way to clear out errant cached files from an iOS application.

To end the Messenger app on the iPhone 13 mini, just follow these steps:

  • Swipe up from the bottom edge of the screen to launch the app switcher or multitasking menu that contains previews of all apps  you’ve recently used and left open/running in the background.
  • Find the Messenger app preview and then swipe it up to close. Do the same to end all other background apps on your iPhone.

After ending all background apps, relaunch Messenger then retry logging into your account. If auto-fill logins are provided, delete the auto-text values then type in the username and password manually. This will help rule out incorrect login details from the underlying causes.

Solution #2: Refresh your internet on your iPhone 13 mini.

Ruling out random network connection issues that result in failed login attempts on Messenger, refreshing the internet connection on your iPhone with the following methods is recommended.

  • Go to Settings->Wi-Fi menu and then turn the Wi-Fi toggle off and on. If you’re on Cellular data, turn cellular data off and on instead.
  • Go to Settings-> Airplane mode menu and then toggle to turn the Airplane mode switch off for a few seconds and then turn it back on again.

If you have set up other Wi-Fi networks on your iPhone, then switching to another network may also be a potential solution especially if the problem is attributed to a corrupted Wi-Fi network in use.

Rebooting the wireless modem or router can also help clear out any transpiring issues affecting wireless internet apps and services.

Solution #3: Restart/soft reset your iPhone 13 mini.

If Messenger was working perfectly fine and suddenly you cannot login to your account even without altering anything on your iOS device settings, then it’s probably just a random system glitch. To clear this out, performing a soft reset or restarting the iPhone can help.

This does not affect any user data saved in the iPhone memory so there’s no need to back up files beforehand. Just follow these steps if you haven’t already:

  • Press and hold the Power/Side button and either Volume buttons for a few seconds and then release when the Power off slider appears.
  • Then, drag the slider to turn your iPhone completely off.
  • After 30 seconds, press and hold the Side button again until the Apple logo appears.

Restarting the iPhone also clears out residual system data including corrupted app cache.

Solution #4: Manually offload the Messenger app on your iPhone 13 mini.

In-app glitches that cause sudden app malfunction can also be addressed by manually offloading the app.

In iOS 15 devices, offloading individual application particularly Messenger, is carried out with these steps:

  • Open the Settings app by tapping on the Settings icon from Home.
  • On the succeeding menu, tap General.
  • Then, tap iPhone Storage.
  • Tap to select Messenger from the apps list and then tap the command to Offload App.
  • If prompted, enter your passcode and tap Offload App again to confirm.
  • The Messenger app will then be dumped from the system.

Offloading doesn’t delete any app data so you can always retrieve the app settings after reinstalling it for as long as the app is still available on the App Store.

After offloading, restart/soft reset your iPhone and then reinstall the Messenger app by tapping on its icon from the Home screen.

Solution #5: Install pending update for Messenger on the App Store.

Installing app updates is also deemed a potential solution to app-related issues including login errors that are inflicted by random software bugs and malware.

Before you proceed, make sure that your iPhone is connected to the internet preferably through a Wi-Fi network, has ample storage space and is sufficiently charged. 

If you haven’t set the App Store to auto-install app updates, then you will need to do it manually with these steps:

  • Go to your iPhone Home screen or App library and then long-press the App Store icon.
  • Select Updates to continue to view all pending app updates on the App Store.
  • If multiple app updates are available, tap Update All. Otherwise, tap the Update button next to Messenger. Do the same to other apps with pending updates.

After updating apps, restart your iPhone to properly save and apply recent software changes.

Solution #6: Uninstall then reinstall Messenger.

Among the last options you’ve got if none of the prior methods is able to fix the problem is to delete or uninstall Messenger from your iPhone. This is often needed if the problem is tied to critical in-app errors and likewise when the app itself gets corrupted.

To uninstall the Messenger app from your iPhone 13, just follow these steps:

  • Go to the Home screen and then touch and hold the Messenger icon.
  • On the quick menu, tap Remove or Delete app.
  • After deleting the app, launch the App Store app.
  • While on the App Store, tap on your Apple ID profile picture then select Purchased.
  • Locate the Messenger app and then tap the cloud icon to instigate app installation.
  • Reinstalling an app is also another way to clear cache and data from an iOS application.

Alternatively, you can delete the Messenger app through the iPhone Storage menu. 

Solution #7: Reset all settings on your iPhone.

To eliminate errant iPhone settings from the possible causes, resetting all settings is also recommended. This reset deletes all custom settings including network details, app permissions and preferences among others. As a result, all default settings are restored.

But unlike a factory reset, the iOS reset all settings command does not affect any user data so you won’t lose any important content saved on your device.

Just refer to these steps should you wish to give this reset a shot in fixing your iPhone 13 mini’s Messenger login issue:

  • Go to your Home screen and then open the Settings app.
  • Scroll to and tap General.
  • Tap Transfer or Reset iPhone to proceed.
  • Then tap on Reset. 
  • On the succeeding menu, tap Reset all settings from the given options.
  • Enter your device passcode if prompted.
  • Tap the option to confirm all system settings reset on your iPhone.

After the reset, your phone reboots automatically and then restores all default values and options.

Still unable to login to Messenger?

Try logging into your Messenger account on a web browser. You can use the built-in Safari app, Chrome or other browser you’ve got and preferred to use.

If you’re able to log into Messenger in the web browser, then it’s probably just an isolated issue with the iOS mobile version of the application.

Perhaps there’s an ongoing problem with Facebook Messenger that results in the mobile version of the app temporarily inaccessible in iOS devices. Server outages are typically resolved on their own so all you have to do is wait and retry logging into Messenger at some other time. Surely downtime issues won’t take too long on these platforms and therefore it should be up and running again in no time.

If this happens to be a post-iOS update problem and it persists after performing all applicable tweaks, then you better have it escalated to either Facebook Messenger support or Apple Support team for further assistance and official recommendations.
