What is “Expire Previous Passcode” on your iPhone and how do you use it?

iOS 17 has introduced numerous security features like a better private browsing mode for Safari, Advanced Tracking and Fingerprinting prevention, and most of all, the Expire Previous Passcode Now feature.

This new feature aims to improve security while ensuring that you don’t have to reset your iPhone, at least for the first three days after you set a new passcode and end up forgetting it. So if you’re wondering what is this new option on your iPhone and how you can use it, then we have the perfect guide for you. Let’s get started.

What is “Expire Previous Passcode Now” on your iPhone running iOS 17?

Have you ever encountered a situation where you change your iPhone passcode to maintain security but end up forgetting it the next day or the day after? Although I am not proud of it, this has happened to me which has led me to erase my iPhone and lose some precious data in the process. Thankfully with iOS 17, Apple now allows you to use your old passcode to unlock your iPhone for up to 72 hours after you have set a new one.

This helps you remember your new passcode or in the worst cases use your old one to unlock your device without having to reset it. However, this also compromises your phone’s security if you changed your passcode to prevent someone aware of the old password from gaining access. This is where “Expire Previous Passcode Now” comes in. This new option allows you to expire your old passcode before the default 72 hours are complete which will help enhance your device security if you’re in a similar situation.

You can use the section below to expire your old passcode if you’re in a similar situation.

Additionally, this option will be unavailable if you haven’t changed your passcode in the past 72 hours.
