New 6 digit passcode request after reset

Same exact thing happened to me. I always had a four digit passcode. A reset was done when the phone was purchased off someone. I had a new phone so just used this as a secondary..no passcode needed to get in to it ever..long story short.new phone got stolen and i did a find my iphone for the wrong phone and it locked me out of secondary phone. Now I cant get in and am being told by Apple only solution is to restore and wipe phone of all its contents...contacts, pics etc. My backup was full so info had not been backed up in years and alot of needed info, bookmarks and pics on this phone. Its now asking me for a 6digit passcode...I never had six digit ..always four..nothing works..every time I try one it makes me wait another hour until i can try another...Apple does nothing for this issue if you call and spend hours on the phone..they actually made it worse by prompting me to delete the phone all together from my icloud account so now i have no info on the phone at all and no proof of it ever being connected to my icloud. HELP Obviously others have had this issue..i need that six digit passcode to use my phone but i only had a 4digit passcode. Not fair apple! Another set up for them to sell more products and phones if you ask me.

This happened to me recently. I had never used a six digit passcode, but when I put a new SIM card in, it requested one. I had success with this fix, but you have to restore the phone. You will lose all your data unless you have it backed up to your computer or the cloud. I was giving my phone away, so I didn't mind restoring it to factory settings.

Good luck!

I suspect what happened is that the phone after the erase asked you to set up a passcode which by default would be 6 digits now. When you entered a 4 digit code, your old one, it did not allow it. You may have set 000000 as the new code. You can now change it to another 6 digit number (which I suggest) or even a 4 digit number by selecting options.

Hello,

Double check that you followed the steps in this article:

When you erase a iPhone it deletes everything. So when it asked for the password it is asking for the new owner to enter their own personal password. It didn't mean your old four digit password.

Go to Settings > Touch ID & Passcode. On devices without Touch ID, go to Settings > Passcode.

Change your passcode: Enter a new six-digit passcode. Or tap Passcode Options to switch to a four-digit numeric code, a custom numeric code, or a custom alphanumeric code.

What helped me was seeing that there's still an option for a 4-digit passcode. Thanks!

I am having the same issue. I had an old iPhone5 and just put in a new SIM card to give it to someone else, and it's asking me for a 6 digit passcode. I never had a 6 digit passcode, but did what dwhitebread did and put in 000000 just to see if it would work and it didn't. I can't get into the phone to set or change the passcode. The SIM card is brand new, so no other passcode was ever entered. Any thoughts?

When one erases a phone there is no passcode at all. Apple does not set one. There is no glitch. If you did not enter the 6 zeros the new guy did. While setting the phone from new, it does ask the new user to set up a passcode and that is what occurred here.

I am having the same problem. I am trying to set up my sons unused iphone 6s with a new SIM card.

After changing the itunes account it asked me for a 6 digit passcode. The iphone always had a 4 digit code.

Read somewhere 123456 works, but it didn`t. I will try 000000. hope it works.

OK, bear with me. You said above:

"I couldn't find any information on this, and was about to give up when I tried 000000. That worked".

That is what did it.
