4 Digit Passcode

Try Turning "Off" the current 6 digit passcode in Settings > Face ID & Passcode

Power off the phone, then restart

Settings > Face ID & Passcode

Turn Passcode On

Look for "Passcode Options" just above the number keypad

Select 4 Digit Numeric Code

I just solved this. I had the same issue but I noticed it started when I added my work Microsoft profile to my phone ( I had to download Intune) I tried uninstalling the applications but this did not help. Here is how I solved it months later:

Go to settings >> general >> VPN and device management >> delete whatever device manager you find there if it is no longer important to you or your work.

I'm running iOS 16.5

Not sure what else to suggest. I can turn off the passcode easily as per the instructions above.

When I go back in to turn on a passcode, the Passcode Options button appears.

Tapping Passcode Options opens the next screen with options to use......

Custom Alphanumeric Code

Custom Numeric Code

4-Digit Numeric Code

I forget my pass code in my limits

I concur with Bob this will work. You will need to setup your Apple wallet again after you do this tho.

go to

Settings

Face ID & Passcode

enter your passcode

Turn passcode off

restart device

Turn passcode on

select options (4 pin passcode)

once done add your cards to Apple wallet.

Thank you. This worked for me. I search all over and realized after reading this that it was related to adding my microsoft email to my phone. Guess I wont be checking my work email from my phone any longer unless I just log in via my browser. What a pain that was!

Read this document which claims you can change it to 4 digit in options. Use a passcode with your iPhone, iPad, or iPod touch - Apple Support

Any luck with this? I am trying to change it back to 4 and am not getting the option to either.
