Did you just change your iPhone’s passcode? Then you have to be careful. Your old access code remains valid for 72 hours!
Old passcode remains valid on iPhone for 72 hours
It is wise to change the passcode of your iPhone every now and then. With Face ID you don’t have to worry about it anymore. But if someone knows your code, they can always unlock your iPhone, even if you just changed the code.
iOS 17 now includes a feature that allows you to log in with the old code for up to 72 hours after changing your passcode on your iPhone. Apple did this because the new code is quickly forgotten due to the use of Face ID.
However, there is also a disadvantage to this. Did you change the code because someone else could accidentally unlock your iPhone? Then it can still be used in your iPhone for up to 72 hours after the adjustment.
Remove old access code
To prevent someone from using your old passcode for another 72 hours, you must delete the old one. To do this, follow the steps below.
Remove old passcode from iPhone
- Open the ‘Settings’;
- Then tap ‘Face ID & Passcode’;
- Enter the current access code and scroll down;
- Then tap ‘Remove previous access code now’.
Use old access code
You will not immediately be given the option to use the old code when you want to unlock the iPhone. Only after entering the incorrect code ten times will you be given the option to use the old access code. You will then first see a screen with ‘iPhone not available’. There you tap on ‘Forgotten your access code?’ at the bottom. Then select ‘Enter previous access code’ and enter your old code.
