Question 1
Hey guys! Can someone please help me? My iPhone 6 Plus has suddenly started acting weird. I was about to unlock it and send some urgent messages, but it didn't work after many attempts, so it is disabled now. I use this iPhone for work, and it's very disturbing, as I am not able to unlock it and make any calls or send texts. My iPhone password is not working but I'm sure it is the correct password (I use it everyday), so I think my iPhone passcode changed itself. I have no idea what happened at all. Please help!
Question 2
My iPhone has a 4 digit number password for the lock screen, but this morning when I woke up, it asked me to enter 6 digit code. I never changed it. It just changed itself. Unfortunately my phone is now locked as a result and needs restoring. This makes me very upset since I haven't backed up my pictures for a long time.

Some iPhone users met such problems —— iPhone password not working or iPhone password changing itself. In such cases, iPhone has been practically locked on its own and not even reading your correct password. What causes such problems is not clear. Sometimes updating the iOS leads to such kind of problem. Anyway, we can still do something when this happens. In this article we are going explain, how to resolve this iPhone password not working or automatic passcode change issue and some tips on unlocking your iPhone. Just keep reading.

1. How Many Times Can You Try Your Passcode on iPhone?

Six failed attempts to enter the password on your iPhone will result in locking you out of your device. If you try to enter a passcode after that, the screen flashes a message 'iPhone is Disabled, try again in 1 minute'. After 1 minute, if you still input incorrect password, your iPhone will prompt you that 'iPhone is Disabled, try again in 5 minute'. If you are repeatedly trying to access it and still entering the wrong password after 5 minute, you must wait 15 minutes until next try. If the problem persists after 15 minutes and it says your iPhone is disabled, further attempt to enter passcode is allowed only after 1 hour.

When you keep on trying this with no success, the iPhone will finally display 'IPhone is Disabled' message along with 'Connect to iTunes' message, and you have no chance to try anymore.

2. How to Avoid Data Loss?

Touch enabled devices such as iPhones, are very sensitive, as a wrong tap or accidental touch might result in irrevocable data loss. But, when your iPhone passcode is not working and you are locked out, you need to be extra careful and prevent any kind of data loss when you try to fix the issue. You might lose all data after 10 failed attempts to unlock your iPhone, if you have enabled the option which erases all the data after 10 wrong passcode entries.

Can you still keep all the data on your device? If your iPhone has been synched to iTunes before and now can be recognized by iTunes, you can definitely make a backup when it is disabled. If not, I'm afraid there is no way to unlock your iPhone without losing data.

You can backup your data by using iTunes or you can make use of a third-party tool like iMyFone D-Port Pro (free backup tool) to selectively backup the iPhone data . It is one of the most reliable tools that offer the useful features such as selective backup, selective restore, and extracting data (almost more than 20 types of data) from iOS devices or backup files. It is compatible with macOS as well as Windows.

Have a look on this step-by-step guide about using iMyFone D-Port Pro for selectively backup data on your iPhone. Download and install the iMyFone D-Port Pro tool in your computer and launch it.
