When All Your Passcodes Stop Working

If every passcode on your iPhone suddenly refuses to cooperate, that’s your device’s subtle way of saying: “Something’s off here.”

1. Wrong Passcode Entered  
   1. It happens to everyone. If you recently changed your passcode (or someone else did), your iPhone won’t accept the old one—no matter how many times you try.
2. Lock Screen vs. Screen Time Passcodes  
   1. These are two separate codes with different jobs:
      1. Lock Screen Passcode: Unlocks your iPhone.
      2. Screen Time Passcode: Manages restrictions and limits.  
3. Restrictions Blocking Access  
   1. Screen Time passcode—whether set by you or someone else—can lock down key functions, including:

• • • Changing passcodes
    • Installing apps
    • Resetting settings
    • Using certain features

Passwords and Passcodes Not Working:

Are you talking about passcodes and passwords for Web sites? Turn off all VPNs. Then see if it works.

If you’ve turned on Face ID for app access, those apps remain locked until your face is successfully recognized. Even if someone has your iPhone in their hands, they can’t open those protected apps without passing Face ID first. It adds an extra layer of security on top of your passcode, making sure only you can get in.
