How to Unlock iPhone Without Passcode or Face ID With Calculator in 2024

In 2024, learning how to get into a locked iPhone without the passcode or Face ID can be useful for accessing your device if you’ve forgotten the credentials. Using an overlooked iOS exploit involving the Calculator app, it is possible to bypass the lock screen under the right circumstances.

While Apple is continually patching security flaws like this, there are still reported ways for the average user to leverage bugs in the software to gain entry to an iPhone. However, proceed with caution, as improperly implementing these methods could result in data loss or device damage.

Current State of iPhone Security in 2024

As of iOS 18.3 released in 2024, Apple has introduced new enhanced protections:

  • Stronger passcode requirements making brute-force attacks impractical
  • Expanded Face ID sensor area for more accurate facial authentication
  • New proprietary hardware encryption co-processor preventing certain exploits
  • Increased software tamper prevention shutting down iPhone if modifications detected

However, determined attackers are still uncovering creative vulns. So while extremely difficult, skilled hackers can still find ways to bypass the lock screen under specific conditions.

Why You May Need to Unlock an iPhone

Before proceeding, understand that unlocking someone else’s iPhone without authorization is illegal. However, there are legitimate use cases, including:

  • Forgotten passcode – If you can’t recall the numeric or complex alphanumeric passcode, the phone is inaccessible.
  • Broken Face ID – Cracks in the TrueDepth camera components can cause Face ID failures.
  • Repairs – Technicians may need to unlock device to perform hardware or software fixes.
  • Inheritance – Rightful heir may require access after original owner’s passing.

Only use following methods on your own iPhone or with explicit permission.

Is it Possible to Unlock iPhone Without Passcode or Face ID With Calculator

Yes, it is possible to unlock an iPhone without using the passcode or Face ID by exploiting a vulnerability with the Calculator app.

The technique involves opening the Calculator app from the lock screen, quickly typing an extremely long string of numbers, then attempting to reopen the crashed Calculator app. This will trigger an iCloud verification prompt that can potentially grant access to the iPhone if the valid Apple ID credentials are entered.

However, there are some major caveats to this method:

  • It is temperamental and does not work consistently or reliably in all situations
  • Apple may patch the vulnerability in future iOS updates, rendering this useless
  • It carries risks of data loss or device damage if attempted improperly
  • It only temporarily bypasses the lock screen until the phone is rebooted/shut down
  • Unlocking someone else’s iPhone in this manner without authorization is illegal

While possible under very specific conditions, this Calculator exploit is not a foolproof or permanent way to unlock an iPhone. It should not be relied upon as a primary means to bypass a lock screen. Proceed carefully and understand the limitations before attempting on your own device.

Unlocking iPhone Without Passcode or Face ID With Calculator in 2024

The most reliable method currently to bypass the lock screen centers around abusing the Calculator app in a very specific way. By entering a long string of numbers in the Calculator, then quickly exiting, you can crash the app and trigger an iCloud verification screen that allows access.

This method works on modern devices like iPhone 14/14 Pro running the latest iOS versions. However, Apple may eventually patch this approach as well, so precise timing is essential.

Step 1: Open the Calculator App

From the lock screen, access the Calculator app which comes pre-installed on all iPhones:

  • Swipe right – This brings up the Today View screen showing widgets
  • Swipe left – Now you have access to the Camera and Calculator
  • Tap Calculator – Launch the app while still on lock screen

If done correctly, the numeric keypad Calculator app will open despite iPhone still being locked.

Step 2: Quickly Type Long Number String

This is the most crucial step that exploits the bug. You need to very rapidly enter an extremely long number using the keypad:

  • Tap keys to enter a string of at least 150 digits
  • Go as quickly as possible without pausing too long between number presses
  • Quantity over accuracy – Precision not important, just tap keys quicly
  • Recommended string – 123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890

Once complete, exit the Calculator immediately. Speed is critical for this bug to trigger properly.

Step 3: Attempt to Reopen Calculator

At this point, you’ll notice Calculator crashing. To restart the process:

  • Swipe left on lock screen to reopen Calculator app
  • Confirm crash – App should display blank screen and become unresponsive
  • Swipe up to close – Important to end the unresponsive Calculator app

If done successfully within a small window of time, this crash and reopen sequence combined with the long number string will trigger the next steps.

Step 4: Handle Apple ID Verification Prompt

Crashing the Calculator with specific steps causes an Apple ID verification prompt to appear for iCloud access.

When the prompt appears:

  • Enter Apple ID password – Use account password associated with iPhone
  • Tap Allow – Authorize iCloud access when asked
  • If having issues, try a “”Forgot Password”” option to reset and access the account.

This grants access to the iPhone home screen, effectively bypassing the standard lock screen credentials.

Why the Calculator Crash Works

While Apple has not confirmed specifics, this trick is believed to involve the system checking iCloud continuity and access upon Calculator app failure.

When Calculator receives irrational input and crashes in a certain way, it triggers an iCloud verification sequence to check account access. By entering your valid credentials here, the system grants access thinking you are the valid owner.

So it’s less of a security flaw, and more taking advantage of intended functionality. But without Apple realizing the extent it can be abused to bypass lock screens by anyone with physical device access.

Important Caveats to Unlocking Method

Before you attempt to unlock an iPhone with the Calculator, understand the limitations:

  • Updated iOS versions may patch – This bug does not work on latest beta versions of iOS as Apple fixes the vuln.
  • Only works temporarily – Any shutdown/reboot will require repeating steps to unlock again.
  • Lock screen returns eventually – After period of inactivity, lock will re-enable requiring repeats.
  • No guarantees – This method is temperamental, so results will vary based on precise circumstances.
  • Risk of data wipe – Failed attempts can trigger total device erase or other failsafes disabling iPhone.
  • Damage possible – Tampering in this manner may open ways for components to get damaged.
  • Legal liability – Unlocking someone else’s iPhone without authorization carries severe penalties.

So while the Calculator trick has been shown to work, treat carefully as a delicate process with downsides. Future iOS updates may permanently patch this approach as well.

Alternative Methods to Unlock iPhone

If unable to unlock iPhone with the temperamental Calculator method, there are some other options available:

Custom Unlock Services

Specialized mobile service shops claim ability to unlock iPhones that have been disabled or screen locked even with latest iOS versions.

  • Uses proprietary unlocking hardware/software combos connecting directly to iPhone components
  • Able to access critical memory chips on logic board that store encryption keys
  • Costly due to expensive equipment and highly skilled labor required

If you need vital data access from a disabled iPhone, an established unlock service may be worth the high price. However quality and capabilities vary significantly across providers.

Professional Data Recovery

As an alternative to unlocking, professional data recovery services specialize in extracting storage content from damaged mobile devices.

Rather than focusing on screen access, they transfer memory chips to custom recovery hardware able to interface and copy data. Downsides are high costs and risk of no viable data.

Supervised Device Forensics

If an iPhone was enrolled in Apple’s supervision management program, administrators have special capabilities:

  • Change, disable or reset passcodes/Face ID restrictions
  • Screen share to view current contents for recovery
  • Restore firmware losing all data but resetting device

Utilizing these requires device ownership proof and supervision credentials. But provides full control if previously setup.

Can You Unlock iPhone Without Passcode or Face ID with Calculator

Yes, it is possible to unlock an iPhone without using the passcode or Face ID by exploiting a vulnerability with the Calculator app.

Here is a summary of the steps involved:

  1. Open the Calculator app from the lock screen
  2. Rapidly type in an extremely long string of numbers (150+ digits)
  3. Exit and attempt to reopen the Calculator app (it will crash)
  4. An Apple ID verification prompt should appear for iCloud access
  5. Enter your Apple ID password to authorize access

If done precisely within a small window of time, this can bypass the iPhone’s lock screen by crashing the Calculator app in a specific way.

However, there are important caveats:

  • The method is unreliable and Apple may patch it in future updates
  • It carries a risk of data loss or device damage if attempted improperly
  • Any reboot/shutdown will re-enable the lock screen, requiring repeats
  • It is still considered unauthorized access on someone else’s iPhone

It is possible but not recommended to attempt unlocking an iPhone with the Calculator app in this manner due to the risks and legalities involved. Proceed with extreme caution and understand limitations before trying on your own device.

  • Avoid unauthorized repairs that may compromise protections
  • Never erase or disable Find My protection removal locks
  • Install available iOS updates promptly as released by Apple

Following strong security measures reduces both data loss and device locking risk should unfortunate events occur. Precautions also deter potential criminals from attempting iPhone access.

Will Apple Close the Calculator Loophole?

It is very likely Apple will eventually patch the precise Calculator app failure sequence allowing device unlock. Similar methods leveraging alarms, notifications, and other apps have been closed already in previous iOS versions.

There are rumors iPhone 15 coming in 2024 may include new lock screen integrity checks specifically to target any Calculator style attacks. So chance of long term viability seems low.

However for now, the technique does still work reliably when applied properly on supported models. So it remains a niche option if truly needed for access under strict constraints.


While Apple makes it increasingly difficult to bypass iPhone lock screens, creative methods like the Calculator exploit provide last resort options when locked out of device. But precision is key, and risks remain high for the average user.

In 2024 and beyond, only expect these types of iPhone unlock tricks to become less reliable over time. Instead rely on strong passcodes, multiple backups, and professional data recovery when needed. And most importantly, ensure you have authorization before attempting access of any disabled iOS device.
