A Step-by-Step Guide for Checking Your iPhone’s Unlock History

Checking your iPhone’s unlock history can be useful for a few reasons, including security, troubleshooting, usage monitoring, and privacy.

Although the iPhone has no “unlock history” feature, checking recently used apps, app activity, and lock screen notifications are possible ways to detect when your device has been accessed or used.

Suppose you suspect someone is accessing your device without your consent or notice any unfamiliar unlock events. In that case, you can easily confirm with the methods above and enhance security on your device.

On the other hand, if you share the device with children, family, or friends, checking the unlock history can let you monitor how regularly your device or some apps are being accessed. This can help monitor usage patterns or to set appropriate usage limits.

Although not everyone will bother about these, knowing that your device isn’t accessed without your permission can give you peace of mind and prevent any potential privacy or security concerns related to the device.

How to Protect Your iPhone From Unauthorized Access?

Since Apple built all of its products (iPods, iPads, iPhones, Mac) with user privacy and security in mind, these devices come with strong security mechanisms that even hackers find hard to crack.

With Touch Unlock, Face ID, password, passcode, and physical security key options, you can protect your iPhone or other iOS device from unauthorized access.

If you feel your current passcode or preferred screen lock option is guessable, moving to a 10-digit passcode or an alphanumeric password combination can ensure more security over your device.

According to an assistant Professor and cryptographer at Johns Hopkins Information Security Institute, Mathew GreenOpens in a new tab., “it will take 12 – 25 years to crack a 10-digit code.”

Gadgethacks explainsOpens in a new tab. that “the possible combinations of a 4-digit PIN is 10,000″, and hackers need only a few minutes to try all of them. Meanwhile, a 6-digit code could take up to 1 million combinations to crack.

Furthermore, Hive SystemsOpens in a new tab. states it takes 504 hours (three weeks) to crack an 18-digit numeric passcode on an iPhone. The combination of numbers and letters increases the difficulty and timeframe for the crack.

Considering these findings, using more digits, you can easily remember makes your iPhone more secure for unauthorized unlocks.

Things to Consider When Creating a Strong Password for Your iPhone

When choosing a strong password for your iPhone, consider the following tips to enhance security and protect your personal information:


Make your password at least 12 characters long. Longer passwords are generally more secure.


Use a combination of uppercase and lowercase letters, numbers, and special characters (e.g., !, @, #, $, %).

Avoid Dictionary Words 

Avoid using common words or phrases that can be found in dictionaries. Instead, opt for a passphrase or a series of unrelated words.

Unique Password 

Avoid using the same password for multiple accounts or devices. Each service and device should have its unique password.

Avoid Personal Information 

Do not use easily accessible information like your name, birth date, or phone number in your password.


Create a password that is random and not easily guessable.

Avoid Keyboard Patterns

Avoid using simple keyboard patterns like “123456” or “qwerty.”


Consider using a passphrase, a longer, easy-to-remember sentence, or a combination of words.

Use Password Manager

Consider using a password manager app to generate and store strong passwords securely.

Change your password regularly, especially if you suspect any potential security breaches.

Enable Biometric Authentication

Use Face ID or Touch ID, if your iPhone supports it, as an additional layer of security.

Two-factor authentication (2FA)

Enable 2FA for your Apple ID and any other accounts linked to your iPhone for added protection.

Test Password Strength

Use online tools to check the strength of your password and ensure it meets the criteria.

Remember that a strong password is a crucial defense against unauthorized access to your iPhone and personal data. Take the time to create a robust and unique password, and prioritize your digital security.

Setting Up a Strong Password 

It is highly recommended to create a six-digit passcode on your iPhone to help prevent unwanted access. Using your iPhone without a passcode is risky and can give room for hackers to access your device. You can check the steps below to create your passcode:

  • Go to settings on your phone and click on Face ID & Passcode

Turn on Passcode
  • To make the passcode harder, click on “Passcode Options”. Different options will appear for you to choose. Numeric custom, alphanumeric, or 4-digit numeric code.

The custom numeric code gives access to create a 10-digit code that has 100 million different combinations. Imagine how combinations of alphanumeric custom codes will have.

This will help create a stronger combination of passcodes. You can check out the Null BytesOpens in a new tab. guide on Stronger Passwords.

Set Passcode

Frequently Asked Questions

Can I check the screen unlock history on my iPhone?

Currently, Apple does not offer a native feature to check iPhone screen unlock history. The device does not log this information, and there is no standard method to access such data through settings or options.

However, checking recently used apps and browser history and looking for unusual actions can help you learn if someone unlocked your iPhone without your consent.

Are there any third-party apps that can show screen unlock history on iPhones?

Apple’s strict privacy and security policies restrict third-party apps from accessing or recording iPhone screen unlock history.

Any app claiming to provide this functionality should be treated with caution, as it might violate Apple’s guidelines or compromise your privacy.

How can I enhance security and monitor device usage on my iPhone?

While you can’t check screen unlock history directly, you can take several measures to improve security and monitor device usage.

Set a strong passcode or use biometric authentication (Face ID or Touch ID), enable two-factor authentication for your Apple ID and critical accounts, and regularly review your device’s app permissions and privacy settings.

Additionally, consider using Screen Time (a built-in iOS feature) to monitor and manage app usage, set app restrictions, and establish Downtime for better control over device access.


Apple prioritizes user privacy and security, so screen unlock history is not accessible through standard settings or options. This design choice ensures that sensitive information, such as unlocking patterns or biometric data, remains protected and private.

If you are concerned about device security or monitoring usage, focus on implementing best practices to safeguard your iPhone.

Set a strong passcode or use biometric authentication (Face ID or Touch ID), enable two-factor authentication for critical accounts, and consider using the Screen Time feature to monitor app usage and manage screen time for better control over device access.

Remember that while checking screen unlock history may not be possible, prioritizing device security and being mindful of app permissions and privacy settings can help you maintain a safe and secure iPhone experience.
