Passcode change itself

The passcode doesn't just randomly change itself. If so there would be millions of users complaining of not being able to access their device. Most likely you used something different and at the time you set it up or changed it there was a reasonable explanation for it but now you don't remember what you used. It happens and the way to fix it can be found here:

Forgot passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

Passwords do not 'change themselves'. The user or any other person with access to the original passcode can change the 4 digit PIN. iPhone's do not just change their PIN's, so somebody has changed it.

As stated by many others, passwords do not just change! Somebody has to physically change the passcode, and either your husband or somebody else has changed the passcode and are not admitting to this.

There is no need to vent on the Apple Communities Support website, as this is a site for customers who require assistance and are offered this by other Apple users, and not a complaints site where you do not provide any helpful information to the original question.

Unfortunately, this seems to be a big problem. Being in IT my first reaction would be that most of the time this is user error. However, I will say that I have had an iPhone 7 for a couple months and have used the same 6 digit passcode since I got the phone. Normally, I use touch id, until tonight. My phone prompted me for my passcode (the same one I've been using for months) and it didn't work. I have had my phone with me all day...no one else has had access to my phone to change the passcode. This is clearly a bug somewhere. Having to resort to a full restore of my phone. I hope I don't lose anything.

Yes, this DOES happen. Stop all the self righteous snark. It's been happening a lot following the latest iOS update, including to me. I have NEVER changed my passcode in 7 years--now all of a sudden it doesn't work.

This happened to my husband. Woke up this morning to his iPhone requesting a 6 digit code when it had previously had a 4 digit number. Unfortunately his phone is now blocked as a result and needs restoring. He is now on an 8 hour flight for a week long work trip with no access to work emails and no means of resolving this until he is back in the UK office a whole week later. As loyal apple customers this is totally unacceptable and will have a serious impact on his ability to do his job. I had always regarded apple technology as enabling but clearly I was wrong.

iPhone 6s here. Just happened to me too. Same problem, same lock code since I bought it, I restarted and pump....my code doesn't work. NOW, I agree on that the code doesn't magically change, I am IT and I know that. However, it should be nice to know how this can happen without the user notice it or at least not realise what he is doing. That would be nice, not just answer "That cannot happen !!". Anyway, my iPhone is locked and not even my finger print can change that. Don't know what to do. Deleted from iCloud maybe ?.

Well ... My iPhone just changed its #code its self too.... same way that people are just saying and i never changed it and no one else, i woke up sent a message by WhatsApp , slept again, woke up and couldnt acces never again to it.

Im about to reset it and lose a lot of stuff.

So im starting to think #SteveJobs let them programmed to take over the #world =)

So yes its real, i dont know how is this happening, but yes, it changed the passcode its self.

thank you for posting yes it does happen!! just happen to me last night after i reset my apple id password. finger print is ok but 4 digit totally doesn't work oddly enough my password worked when i accessed restrictions in settings. sorry ppl can be so lame with their condescending responses😟

I do actually, but not one that anyone besides an engineer on the iPhone team could answer. This issue is real it just happened to me where I'm locked out of my iPhone 6S after the latest update to iOS 10.

What I'm railing against in my posts is that a lot of people on this community think that just because something is _not supposed_ to happen that it's impossible and must be human error that's causing the issue.

I've had the same passcode on my iPhone for several years (across different models). This morning that same passcode does not work. I haven't even opened settings in the last few weeks except to add wifi networks. I just feel bad for people who've had this issue, but are being talked down to with "user error."

I did not have a passcode on my Iphone 6s, I had it in my pocket. I went to use it and it asked me for a six digit passcode and locked me out. I had to nuke and pave to use the phone and lost everything.

THIS IS A BUG. There is no way I butt dialed a six digit pass code in my pocket.

No.... You are not crazy!

And no.... You didn't sleep walk one night and change your passcode accidentally.

Keep In mind that people that say "can't happen" are ignorant.

Of coarse it can happen .... and did happen.

Anything can happen.

Apple is in the process of changing to a 6 digit passcode system.

I have 7 iPhones.

I recently upgraded a 5C to a 6s that requires a 6 digit passcode. Suddenly my 5C generated a new random passcode.

If you thing Apple doesn't know about this problem ...... What can I say?

Try to restore it as a new phone.

Good luck.

I had a six digit passcode on my iPad. I tried to use it this morning and it is asking for a four digit passcode. I have tried putting in the four digit passcode I used Pruitt to changing it to six digit code but this does not work. No one had access to it after I used it last night - (it was on my bedside table with earphones attached).

Yep it happened to me. Watching tv picked up phone that was laying next to me and passcode changed. Only fix was to erase and restore.

Big problem with the new 2 factor authentication is that to access iCloud on an erased or new phone you have to enter the six digit code that has been sent to your iPhone........my disabled recently erased inaccessible iPhone. Oh and at some point in the 2 hour process I was asked to enter my new passcode and my old passcode. Luckily my wife has an iPhone and I could get the code sent to her

This is the second time my iphone 7+ changed passcode itself. I have been used the same passcode. After a full charge overnight, I was asked for a 6-digit passcode to access my iphone. My passcode was a 7-digit number.

The exactly same thing happened last month -- I had to reinstalled the phone and everything else. A painful process.

I didn't use authentic Apple charger or cable. Not sure whether that was the culprit.
