Apple iPhone 6 Backup Password Never Set But Still Asking? Here’s the Fix

Part 1: Why Do iTunes Ask Me for iPhone Backup Password?

When you use iTunes to create a backup, the backup will probably have a password that iTunes automatically create. This is for privacy reasons. Hence, it might ask for an iTunes backup password never set by you!

In most cases, this occurs when the Encrypt Backup option is activated. As an official iOS feature, its purpose is to provide iOS users with the iTunes backup encryption for further security.

encrypt local backup

Unfortunately, this capability may also become problematic if you inadvertently take a backup without being able to provide the password. For example, you may have to enter the password for your Apple iPhone 6 backup unlocking never set by you.

But the good news is you have some possible fixes. So, let’s talk about them.

Part 2: 4 Possible Ways to Fix Asking for iPhone Backup Password

Many iPhone users have problems with iTunes when they back up their devices.

One of the most common issues is that people are asked for their iPhone backup password never set, but they need to know what it is. This can be frustrating because you can only back up your device if you have the password.

There are a few possible ways to fix this problem. Try resetting your password or using a different computer to back up your device. You could also try using a third-party software tool like Dr.Fone - Screen Unlock.

1. Try all passwords you use on iPhone

When iTunes prompts you for an iPhone backup password never set, what should your initial course of action be?

To get out of this predicament in the simplest way possible, try entering every potential password you will likely have used. In most cases, individuals will use the same password for many accounts.

A significant possibility is that you encrypted the iTunes backup with the same password from the iCloud account.

Therefore, before doing anything further, try all passwords to configure your iTunes account. For example, try entering 0000, 123456, name123, or 1111.

2. Find the password from Keychain on macOS

You may also attempt to find the password for the iTunes backup using the keychain approach if you are working on a Mac.

The likelihood of success with this approach is relatively low. However, it is still worthwhile to try it, particularly if you have also synchronized your iTunes account with your Mac.

  1. On your macOS, go to Utilities by clicking the Applications menu item. At this point, launch the Keychain Access app and look for your Apple iPhone 6 backup.
  2. To open a new dialogue box, double-click the most recent backup file, and you will see one appear before you.
  3. On this page, choose Show Password to get the password for the Apple iPhone 6 backup. However, you will first be prompted to provide the administrator password associated with your iCloud account to recover the password.

3. “Reset All Settings”

Resetting the password is another option at your disposal if you encounter the Apple iPhone 6 backup password never set problem. How you do this will be different depending on the version of iOS that you have installed.

Here are what you can do with your iOS smartphone if it has iOS 11 or a later version:

Step 1: Unlock your Apple iPhone 6, and then open the Settings app on your device.

Step 2: After locating the General menu, go to the Reset menu and then hit the Reset All Settings button. Please confirm your action by providing the password for your Apple iPhone 6.

reset all settings

Step 3: Once the reset has been completed, your previous password will be deleted.

Step 4: The next thing you should do is take a fresh backup of your Apple iPhone 6 using iTunes, and then establish a new password for the backup that iTunes creates.

You will need to use an alternative strategy, which includes a factory reset if you use an older version of the iOS firmware than iOS 11.

Step 1: Before continuing, it is highly recommended that you create a backup of the data on your Apple iPhone 6 using iCloud.

Step 2: After you have opened the Settings app, go to the General menu, then to the Reset menu, and finally to the Erase All Content and Settings option.

reset in settings

Step 3: Confirm that you want to reset your Apple iPhone 6 to factory settings, and wait until it is done.

Step 4: Once the factory data reset is finished, you must restore your iCloud backup. To do this, follow the steps for setting up iOS until you reach the Apps & Data option.

Step 5: Create a new backup in iTunes and change the password for the existing backup in iTunes.

You should be aware that resetting the Apple iPhone 6 device to factory settings will not make your encrypted backups accessible again.

On the other hand, it does make it possible for you to generate a fresh backup in iTunes that is not encrypted.

4. Dr.Fone-Screen Unlock

First step: After installing Dr.Fone on your device, please run the program and look for the red button labeled “Screen Unlock.”

Step 2: While in the interface for Screen Unlock, navigate to the bottom right of the screen and tap on the feature labeled “Remove iTunes BackUp Encryption.” This will allow you to proceed.

Step 3: When brought to this screen, please use a USB cord to connect your iOS device to your personal computer. If Dr.Fone can identify this relationship, the following picture will appear for you to see.

Please read the following three notes carefully before clicking the “Remove Now” button:

  • Check to ensure that “Find My iPhone” is not turned on.
  • During this procedure, you should not launch “iTunes.”
  • During the process, your Apple iPhone 6 will restart.

Step 4: If you have an iTunes backup, Dr.Fone may automatically verify it and delete it. This encryption will be removed once the percentage on the progress meter reaches the end. This procedure won’t take a lot of time at all.

Step 5: The encryption of the iTunes backup has been successfully erased! Your backed-up data may be quickly restored, transferred, wiped clean, and backed up again. Hence, you can enter the password to unlock your Apple iPhone 6 backup never set in the first place!

The Bottom Line

There are four ways to fix the problem if iTunes keeps asking for your Apple iPhone 6 backup password. The first method is to try all the passwords you use on your Apple iPhone 6. You can try finding the password from Keychain on macOS if this does not work. Another option is to “Reset All Settings” on your Apple iPhone 6.

Lastly, Dr.Fone-Screen Unlock is a program that can help you bypass the passcode and get into your backups. So, what are you waiting for? It’s time to avoid the problem of iTunes backup password never set.

How To Remove Flashlight From Apple iPhone 6 Lock Screen

Ever wonder why the flashlight shows up on your Apple iPhone 6 lock screen? Especially when it happens in your pocket or while you’re holding it. If you, like many, accidentally turn it on and drain your battery, no need to worry.

While you can’t remove it, figuring out how to remove flashlight from iPhone lock screens is a common question. This guide shares several ways to prevent accidental activations and save your device’s battery. Keep reading for easy solutions to take charge of your Apple iPhone 6’s lock screen and make it work better for you.

Part 1: How To Remove Flashlight From iPhone Lock Screens?

You can’t remove the shortcuts like the flashlight icon from an iPhone lock screen. These are built-in features, and Apple doesn’t currently offer an option to disable them. However, there are some workarounds to make the flashlights less accessible and avoid turning them on accidentally. You can turn off Tap to Wake, Raise to Wake, remove the flashlight icon from the control center, and turn off the Back Tap shortcut.

Find out the steps below.

Quick Fix No. 1: Turn Off Tap To Wake

Tap to Wake lets you light up your Apple iPhone 6 screen with a simple tap. It’s handy, but there’s a catch – tapping near the bottom right corner might accidentally turn on the flashlight icon. The Tap to Wake feature can be troublesome, especially in the dark, when you don’t want any unexpected brightness.

Turning off the Tap to Wake feature is not directly related to the issue of iPhone users wanting to remove the flashlight from lock screens. However, adjusting settings like Tap to Wake can be part of customizing the overall user experience on an iPhone. When turned off, the screen won’t light up with a tap, reducing the likelihood of accidentally triggering the flashlight.

Here is how to turn off the Tap to Wake feature:

  • Step 1: Go to Settings or General > Accessibility on your Apple iPhone 6 device.
  • Step 2: Toggle off Tap to Wake.

Quick Fix No. 2: Turn Off Raise To Wake

With “Raise to Wake” enabled, simply picking up your phone can activate the lock screen. Consequently, the flashlight icon becomes more susceptible to accidental touches. To address this, turning off this feature stops the screen from waking when you lift your Apple iPhone 6. By doing so, it becomes less likely that you’ll accidentally turn on the flashlight when you pick up your iOS device.

Here is how to remove flashlights from iPhone lock screens when not needed:

  • Step 1: Head to Settings > Display & Brightness on your iOS device.
  • Step 2: Toggle off the Raise to Wake option.

Quick Fix No. 3: Remove the Flashlight From the Control Center

The Control Center on iPhones is a quick-access panel. You can access it by swiping down from the top right corner of your screen. There, you can control various settings, like the flashlight. If you remove it, the flashlight becomes less accessible from the lock screen. Follow these steps to remove the flashlight from the control center:

  • Step 1: Open the Settings app and navigate to Control Center.
  • Step 2: Tap on Customize Controls, then find the Flashlight icon.
  • Step 3: Tap the red minus (-) sign next to the Flashlight icon.
  • Step 4: Tap Remove to confirm deleting the Flashlight icon from the Control Center.

Quick Fix No. 4: Turn Off Back Tap Shortcut

Back Tap on the Apple iPhone 6 lets you set actions for double or triple taps on the back. One of these actions is turning on the flashlight. If you often tap your phone’s back, you might accidentally activate the flashlight. Turning off the Back Tap for the flashlight prevents these accidental activations.

Although the flashlight icon remains on the lock screen, you won’t accidentally turn it on by hitting the back of your phone. Here’s how to disable the Back Tap for the flashlight shortcut:

  • Step 1: Go to Settings > Accessibility > Touch > Back Tap.
  • Step 2: Select the Double Tap or Triple Tap option you’re using for the flashlight shortcut.
  • Step 3: Choose None instead of the currently assigned action, which might be Flashlight.

Now, let’s address turning off the flashlight on your Apple iPhone 6. Even if you’ve applied Part 1’s solutions, knowing how to switch off the flashlight is crucial. In this section, you’ll learn how to turn the light off on iPhone devices.

Method No. 1: Turn Off the Flashlight in the Control Center

You can’t remove the flashlight icon from the lock screen, but you can still turn it off easily. Just swipe down from the upper-right corner or swipe up from the bottom (for iPhones with a Home button). Then, follow these steps to discover how to turn off the flashlight on your Apple iPhone 6: Here’s how to do it.

  • Step 1: Find the flashlight icon in the Control Center. It’s usually located in the bottom left corner.

This method is fast and convenient, especially if you’ve kept the flashlight icon in the Control Center. Plus, it works regardless of how the flashlight was activated, even if it was an accidental tap on the lock screen.

Method No. 2: Use Siri To Turn Off Flashlight

To go hands-free and avoid accidental taps, you can use Siri to turn off the flashlight. For those who favor a hands-free approach, it offers an alternative method, particularly if you haven’t customized the Control Center. Here’s how to turn off the flashlight with Siri on your Apple iPhone 6:

  • Step 1: Say “Hey Siri” or press and hold the power button (or Home button on older iPhones) to activate Siri.
  • Step 2: Give the commands saying, “Turn off the flashlight.”
  • Step 3: Siri will confirm your request and turn off the flashlight. You’ll hear a voice cue and see the flashlight icon on your screen dim.
