How to Password Protect / Lock Applications on iPhone with LockDown

As an iPhone owner, many of my fiends love to have a quick look at this Apple’s sweet device. There’s no problem with that But my concern is that I can’t lend my iPhone without potentially giving them access to lots of personal data. (Email App, Messages, Contacts, Call history, browser history,  etc.)


Unfortunately, even in iPhone 3GS, we can only set a passcode to gain access to iPhone’s home screen but we don’t have App-Specific password protection. I don’t mind passing my phone around at a party to share a YouTube video or funny web site, but you have to keep a close eye on people to make sure they don’t go messing around with things they shouldn’t be.  Like I don’t want others to have access to Email App or SMS or Photos.

Once again Thanks to the Jailbreak Community where iPhone users can enjoy the App-Specific password protection. A free iPhone App: LockDown, available in Cydia has the ability to Password protect your desired application on iPhoneLockDown works like a charm on iPhone OS 3.0 and also supports 2.x firmwares as well.

How to Password Protect/Lock Applications on iPhone

Let me give you a walk through of LockDown.

How to install LockDown

Update: Lockdown is supported upto iOS 3.1.3. for iOS 4.x or later, you should get LockDown Pro or Locktopus.

To install LockDown, you need to jailbreak your iPhone first. Learn how to jailbreak your iPhone:

    Once you have jailbroken your iPhone. You’ll got a Cydia icon on your SpringBoard.

    1. Launch the Cydia.
    2. Go to Search Tab and search for Lock Down and tap it.
    3. Tap Install button at Top-Right and then Confirm button at Top-Right to begin installation.
    4. After completion, go back to Springboard where you’ll find a brand new icon i.e. LockDown.



    How to use LockDown

    • When you will run the Lockdown application for the first time, you will be asked to setup a Safety Code and a Password. This password will be used to unlock any locked application and to open Lockdown itself. Safety code is useful in case you forget your LockDown password.
    • Once you have setup the Password and safety code, you will see all your iPhone applications listed on next screen.
    • Select any application you want to lock, a Lock button will appear. By tapping that button your selected application will be locked and a little lock icon will appear next to that locked application.
    • Now if you close LockDown App and try to open you locked application (Mail app in this example), you will be prompted to enter the password to open it. Use your Lockdown password to open that App.

    (Once you open the app, use it and when you close the app it will be automatically locked again. So no need to re-lock it in LockDown.)



    Lets check other options in Lock Down.

    • Tap LockDown to launch it. This time you’ll be asked to input the password to open LockDown. Do it.
    • Tapping any locked application in LockDown will prompt you if you want to Unlock it. Pressing the Unlock button will perform the unlock that App.
    • Locked Applications button at the top right quickly shows all the locked application only  rather scrolling through all applications to locate locked ones.
    • Under Settings tab at Bottom, following options are available:Locking Options
      • Lock All Applications
      • Unlock All Applications
      • Lock This Application (ON/OFF)

      Password Management

      • Change Saftey Word
      • Change Password
      • Forgot Password

      Other Settings

      • Lockdown Dylib (If you turn it OFF, even if you open a locked application it will not prompt for password. So, it’s helpful when you are using your iPhone by yourself. See the details in screenshot. )
      • Lock Icon Moving (When turned ON it do NOT let anyone to move any icon to preserve your arrangement of icons.)
      • Lock App Deletion (When turned ON it do NOT let anyone to delete any application without your permission.)
      • Enable Launch Button (When turned ON, Lockdown will show a launch button when you open a locked application and input password.)



    I am using this great application since the day it’s supported with iPhone OS 3.0. It’s working like a charm and will keep it installed because of its usefulness and surely recommend it.

    This seems not to work on 3.1.2 . Any advice?

    iPhoneJailbreaker January 17, 2011, 9:31 am

    Klaus, the same thing happens to me and it’s getting annoying…I downloaded it to keep my little brother from accessing certain apps and got really excited when I heard about it…but I guess it doesn’t work for 3.1.2.

    Paperinik January 3, 2010, 6:30 am

    Dear Klaus, I have the same problem. It was working fine before I upgraded to firm 3.1.2…….

    Michael November 12, 2016, 7:03 pm

    I cannot believe that apple still allowed their phones to be jailbroken. Come right

    Paperinik January 3, 2010, 6:38 am

    PS: I am using CATEGORIES but I don’t this app is the cause of the problem. I tried to lock an app that it’s not managed by CATEGORIES…but the result doesn’t change.

    bastardus January 18, 2010, 7:24 pm

    i have the same problems.. v 3.1.2 when i want to unlock an locked app or folder i allways get an error and the iPhone goes to safe mode.. Anny other progs. for locking stuff on the phone??

    Ashlique January 19, 2010, 4:39 am

    I wanted this app because my 2 year old daughter likes to move and delete apps, and call people randomly. The first time I tried to get into a locked app, my phone went into safe mode. (OS 3.1.2) I rebooted and tried again just in case, and it worked perfectly fine. Thanks so much!

    cordrcuk February 2, 2010, 8:19 am

    Same, working fine and now, freezes and safe mode ALL THE TIME!

    iPhoneHeat February 2, 2010, 9:25 am

    OS compatibility issue

    zarahsayed April 4, 2010, 3:56 pm

    i did not face any prob with version 3.1.2 , however the application does not work if u have a message comin frm a frd and u just click on view and it will display the message without asking for a lock code

    Bluffmaster April 17, 2010, 10:26 am

    nice app….
    i’ve been waiting for this one from a long time.
    now i can give my iphone to anyone.

    MMMMM April 21, 2010, 9:21 am

    How if i enter the wrong password for more than 5 times?
    is there any wrong password entry limit?
    or what will happen after exceeding the limit?

    thetrystero May 4, 2010, 11:42 am

    if they are you fiends, you probably don’t want to let your iphone anywhere near them anyway.

    Kannan May 12, 2010, 5:20 pm

    Iprotect is another good application like mdv. it too has sim protection.
    Since the applications locked work on a single password, I have used both lockdown and iprotect.
    Since my kid uses my iphone to play games, I lock critical applications with iprotect and her games and other common applications with lockdown (whose password she also knows).

    Nainesh June 29, 2010, 12:50 pm

    Thanks ppl. It worked perfectly for me. I’ve been wanting to lock my sms tab for quite sometime now.

    Doesn’t work on iPhone 3GS. Freezes the phone, I had to uninstall it.

    josh October 13, 2010, 3:36 am

    I’ve downloaded this and iProtect on my iPhone4 with OS 4.1
    My problem is that both applications when checked to “disable app deletion” and try to delete an app, it still deletes. How can i fix this?

    Hoho October 24, 2010, 4:10 pm

    Same problem!

    ace October 14, 2010, 3:50 am

    It worked, yes it works. I have the iphone 3g 3.1.3. I hated that i couldnt lock individual apps before. Hand someone your phone and they can look at your texts and pics and email, all kinda crazyness. Leave your phone laying there and chicks going through your texts, this sofware is great and it works, i was going to get another phone soon just becuase of the security but now im gonna keep it. GOOD WORK FOR THIS APP!!!!!!!!!!

    jhayton October 15, 2010, 7:51 am

    not working on my 3g 😐

    jhayton October 15, 2010, 7:53 am

    i think its just available on iphone the old generation ?

    jdks October 28, 2010, 5:04 pm

    is this for free?

    Thromp February 16, 2011, 10:20 am

    Does this work to lock down the network settings so that 3G/Edge/Cellular Data settings can’t be changed? If not, anyone know an app that will do that?

    alemdar February 22, 2011, 12:10 pm

    Thank you

    Paige March 3, 2011, 7:56 pm

    If you have 3.1.2 and downloaded this and it ended up not working always ending up in safe mode. You can remove Lockdown by leaving it on safe mode then clicking cydia > manage > packages then school down until you see lockdown and remove it. Everything should be working fine after that.

    Iman May 4, 2011, 11:00 pm

    when i entered a new safety password, and went to the application page but no application was listed and i need this application…what should i do??

    Asad May 17, 2011, 1:54 am

    Asad May 17, 2011, 1:54 am

    John August 7, 2011, 10:21 pm

    It will be listed in your settings app as “LockDown” or “LockDown Pro” and you can configure from there.

    Tata October 16, 2011, 6:15 am

    Stop fucking whining and do some reading, not working on ya phone, also fuck up your phone? WHY? Did you make sure it compatible with ya OS version, ur device, what source ya get it from, ect….?

    someone suggested i download lockdown pro. I did .. and while it worked like it was supposed too.. there are still major loopholes. I only wanted to protect my photos. But if i use whatsapp and try to send a photo through the chat .. then i can easily access it without a password. I had even found out some other consistencies in the app before.I message the developer..
    which one should i use ?
