How to Change 6-Digit Passcode to 4-Digit on iPhone (Any iPhone)
Most iPhone users don’t realize this, but Apple still allows a 4-digit passcode on iPhones—even on the latest models running modern iOS versions. If you’re tired of entering a 6-digit passcode every time you unlock your device, this guide will show you how to switch back to a 4-digit numeric passcode in under a minute.
This method works on any iPhone, whether it uses Face ID or Touch ID, and it does not require any third-party apps.
Why Would You Want a 4-Digit Passcode?
Apple sets a 6-digit passcode by default because it offers better security. However, many users still prefer a 4-digit passcode for speed and convenience.
- Faster unlocking
- Easier to remember
- Helpful for seniors or kids
- Useful on secondary iPhones
- Less friction when Face ID or Touch ID fails
The option still exists—you just need to know where to find it.
Does This Work on All iPhones?
Yes. You can change from a 6-digit to a 4-digit passcode on:
- iPhones with Face ID
- iPhones with Touch ID
- Older iPhone models
- New iPhones running the latest iOS
As long as your iPhone supports passcodes, this method will work.
Important Security Note
Before switching, it’s important to understand the difference:
- 6-digit passcode: 1,000,000 possible combinations
- 4-digit passcode: 10,000 possible combinations
A 6-digit passcode is significantly more secure. Choose the option that best fits your usage and security needs.
