Authentication locked on screen.

My Ipad screen has the authentication proxy window on the screen and it won't go away. It won't accept or cancel my password and I am unable to power the unit down and restart it. I've tried reconnecting it to my computer but it still won't go away and it has rendered the iPad as useless. Solutions?

Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • How do you lock the screen on iphone 4?

    How do you lock the screen on iphone 4 while on a call? I mute calls, activate face time and I have even called someone by accident during a call. I know there has to be a way to fix this. Please HELP!

    It locks automatically when you hold it to your head.
    If it fails to do this, then remove the case and see if it solves it.
    If it does not, then do the basics - restart, reset, restore.
    If that does not solve it, then make an appointment at the genius bar.

  • How can you lock the screen on iPhone in iOS 7 while talking on the phone?

    I am struggling to figure out how to lock the screen of my iPhone 5 during a phone call. In iOS 6, I was able to push the top "on/off" button to lock the screen. In iOS 7, I am able to do this ONLY while using the speakerphone. If I push this button while talking on the phone regularly or using a headphone, it ends the call rather than locking the screen.
    I have found that I am muting calls and disconnecting calls accidentially with my "face" while holding the phone b/c the screen is so sensitive. Does anyone know a way around this?

    I dont know of a way round this, but im having the same issue of puttig people on hold when putting the phone up to my ear.
    This was an issue with the iphone 4 years ago and apple had to do an update to cure it

  • Can you lock touch screen when watching videos!??

    Can you lock the screen so it doesn't become a touch screen when watching videos!??
    Just got new ipod (7th gen) and this driving me crazy that I think I'm going to continue to use my older one unless there is a solution out there. I watch tv shows while commuting and while walking here or there I have to 'palm' the ipod or walk with it at my side, and the problem is that since the touch screen is sooooo sensitive I keep fwding/rewinding/swiping the screen to something else, and then to get back to that part in the video is a pain because unlike the older ipod you can just fwd a few secs, this one jumps minutes because it's so sensitive. PLEASE tell me there's a way to lock it from accidently touching it!

    No - there is no such switch on the iPad - the switches control volume, muting, screen rotation, and the home button itself.
    You could place it behind a screen of some sort so touching the outer screen won't affect the iPad screen - I've seen ads for 'presentation kiosk' type devices for the iPad that allow this, although I'm not sure how practical they would be in the backseat of a car.

  • Looking for an App to Lock the Screen while Playing a Movie

    I've been looking for either an app to lock the screen (not turn the screen off like the button on top of the phone) while playing a movie or a media player that will prohibit you from pressing buttons while a movie is playing. The reason I'm looking for this is my son likes to watch movies on my iPhone while we're in the grocery store, but I spend more time restarting the movie or navigating back to the iPod app and restarting the movie than he spends watching it! He likes to press the "done" button or home button which ends the movie. So an app that would prohibit that would be GREAT, but I haven't been able to find one so far. Any suggestions?

    An app will not be able to do this.
    Sorry.

  • Problems after upgrading to 4.2. Not able to lock the screen.

    I updated the software of my IPad to 4.2 yesterday and I can now not lock the screen, so it does not turn when moving the ipad. The button that I used to lock the screen now turns the audio off/on.
    Has anyone experience this problem and does anyone know how to solve it?
    Many thanks,
    Myra

    4.2.1 is designed to operate that way.
    The hardware switch does not turn the audio off/on. Rather, it turns the alerts (from email, etc.) on/off so that you can listen to music or movie sound without the annoying alerts.
    If you need to lock the orientation, tap the Home button twice. When the "Recent" tray appears slide it to the right. A software switch is at the extreme left.

  • The top button on my iphone 5 stopped working recently.. Well it works but barely at all if every. Most of the time it only locks the screen if I click on the left side of the button. Also my Camera causes a blue pixelated spot on pictures I take.

    The top button on my phone recently stopped working. Well sometimes. Majority of the time if I click it hard enough on the left side of the button it will lock the screen... Otherwise it doesnt work at all anymore. Also the camera appears to be placing a blue pixel on pictures I take. Its annoying. What should I do?

    It's completely situational. Without being able to directly compare the "scratch" on the original poster's iPhone with your iPhone, what gaamcc had happen could not be extrapolated to guess what Apple may do in your situation. It will depend entirely on what the Apple technician diagnoses after examining your iPhone. He/she may decide that any damage is strictly cosmetic and didn't have any connection with the problem you're taking your iPhone in for, or he/she may diagnose the problem as stemming from user damage. You'll just have to see when you go to the Apple Store.
    Regards.

  • Some how I have locked my Screen and it will not rotate.  I tried to unlock it double taping Home but it didn't unlock it.  I'm sure this an easy fix but I'm a new iPad 2 user.

    Some how I have locked the screen on my iPad 2 and can't get it to rotate.  I tried double tapping the Home key but it didn't make a difference.

    Double tapping the home button won't unlock your screens orientation.  Double tapp the home button and swipe the bottom row of apps that appear and swipe them to the right all the way until an icon appears on the left side.  It should be either a mute icon, or orientation icon.  Hopefully, since your screen is not rotating, it will be the screen lock.  Touch the icon and that should solve your problem.

  • Can't lock the screen anymore with a password

    I can't lock the screen anymore since I installed Mavericks. I have assigned a password to the screensaver in the system preferences, but when I activate the screensaver on my iMac 8,1 it does not ask for the password when I wake it up from sleep. I have checked the option in the security preferences that the Mac should ask for a password immediately.
    Any idea how the enable the password?

    Okay, the problem is solved. I don't really know how - I just restarted the mac several times and now it works.

    Email address hacked via iphone. iphone locked home screen displaying my email password! and has been reset. now unable to restore iphone, saying i do not have permission

    If you don't know your password, don't know your security questions and don't have a rescue address or don't receive a reset email, you should contact AppleCare who will initially try to assist you with a reset email or if unsuccessful will pass you to the security team to reset your security questions for you.
    If you are in a region that doesn't have international telephone support try contacting Apple through iTunes Store Support.

  • Window not refreshing after lock/unlock screen.

    I've noticed an issue where if I lock the screen (windows key + L) before the visible property of some component is changed, then unlock the screen, the component visibility is not updated until I mouse over the JavaFX application window.
    I'm including some sample code to demonstrate the problem. To use:
    1. Run.
    2. Click the button.
    3. Lock the screen.
    4. Wait 15 seconds.
    5. Unlock the screen, but do not touch the mouse.
    6. Verify that the progress indicator animation is still visible, but is not animated.
    7. Mouse over the application window.
    8. Verify that the progress indicator disappears.
    In addition, if steps 3-7 are not executed, the behavior is as I would expect... The progress indicator disappears 15 seconds after the button is clicked.
    Does anyone have any ideas on a workaround that would force a UI update when the screen is unlocked?
    I'm using the version of JavaFX packaged with Java 1.7.0_09
    * App javadoc goes here..
    public class App extends Application
         * @param args
        public static void main( String[] args )
            Application.launch(args);
        @Override
        public void start(Stage stage) throws Exception {
            VBox root = new VBox();
            final ProgressIndicator pi = new ProgressIndicator();
            pi.setMaxSize(300d, 300d);
            pi.setStyle("-fx-progress-color: dodgerblue;");
            Button button = new Button("Hide after 15 seconds...");
            button.setOnAction(new EventHandler<ActionEvent>() {
                @Override
                public void handle(ActionEvent arg0) {
                    pi.setVisible(true);
                    Thread t = new Thread(new Runnable() {
                        @Override
                        public void run() {
                            try {
                                Thread.sleep(15000);
                            } catch (InterruptedException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            } finally {
                                Platform.runLater(new Runnable() {
                                    @Override
                                    public void run() {

                    t.start();
            root.getChildren().addAll(pi, button);
            Scene scene = new Scene(root);
            stage.setTitle("Lock/Unlock Windows Issue");
            stage.setScene(scene);
            stage.show();
    }

    The Java8 and see if it has been fixed:

    If not, check the JavaFX issue tracker for a duplicate (it's probably already logged there), if not, then log an issue against the runtime project:

  • How to lock the screen in OS X?

    im new to Mac. been a PC user for over 10 yrs. I'm just wondering if OSx has a similar shortcut to lock the screen just like what you can do with "windows key+L" in XP.
    I know i can do that with screen savers or just log off. But i just wanna know if there is an easier way. Thanks.

    What about using the Sleep command?
    APPLE > SLEEP
    It puts your display and computer asleep. You can set it so that it requires you to insert your password to awake the computer from sleep mode or even your screen saver for that matter.
    Open System Preferences then go to Security section. Then find the check box that says "Require Password to wake this computer from Sleep". Check it.
    There's also an application that locks it and sets an alarm off when it is touched, tracked pad moved, keyboard or taking out your power adapter. It's called iAlertU. iAlerU - Version Tracker. You use your remote.
    Open it in your applications folder. It's then added to your menu bar. Hold down the Menu button for 2 seconds on your apple remote until you hear a car lock sound. Do the same to unlock it.
    Remember to mark as helpful or solved.

  • Email stops synching after 15 minutes (when it locks the screen). Any thoughts?

    I got the Droid 2 yesterday.  Email account (syncs to corporate email) works fine until the device goes to sleep (or what ever it does after 15 minutes that locks the screen then you have to enter a PIN to wake it up again).  Even after entering the PIN, I need to go into the email application for it to synch.  Seems to me like it should sync with email irrespective of whether the screen is locked or not.
    I've run the Droid Power app and ensured sync is green
    Battery mode is in Performance mode (to ensure it would always sync)
    Email delivery is set to Data Push ON with a Fetch schedule of 15 minutes; Synch over WiFi Only is NOT checked
    I got the newest OS update this morning, but still no joy.
    Does anyone have any thoughts on what else I can try?
    Thank you,

    This may be nothing may than a simple software issue. I recommend performing a hard reset then re-enabling the sync. The steps to perform the hard reset are below:
    To reset your phone to factory settings and erase all
    the data on your phone, touch Menu > Settings
    > Privacy > Factory data reset > Reset phone.
    Warning: All data on your phone will be deleted.
    (Nothing on your memory card is deleted.)
    To reset your phone to factory settings and erase all the data on your phone,
    touch Menu
    > Settings
    > Privacy
    > Factory data reset
    > Reset phone.
    Warning: All data on your phone will be deleted.(Nothing on your memory card is deleted.)
    Hope this helps.
