iOS: Forgotten passcode or device disabled after entering wrong passcode

Summary

Learn what to do if you have forgotten or can't remember your passcode, or if you see a red "disabled" message.

Products Affected

iPad, iPhone, iPod touch

When you set up a passcode to secure the use of your iPhone, iPad, or iPod touch and you then enter the wrong passcode, you may see a red "disabled" message. If you forgot or can't remember your passcode, follow the steps in this article to resolve the issue.
If you enter the wrong passcode six or more times, you'll see a message that says one of the following:

• iPhone is disabled
• iPad is disabled
• iPod touch is disabled

The message says to try again later:

After too many attempts, your device may display, "[Device] is disabled, connect to iTunes".

If you have previously synced your device with iTunes

You may be able to reset the passcode by restoring the device.

1. Connect the device to the computer with which you normally sync and open iTunes.
   Note: If iTunes prompts you to enter the passcode, try another computer that you have synced with. Otherwise, go to "If you have never synced your device with iTunes", below.
2. Right-click the device in the left column and select Back up.
3. When the backup is complete, select Restore.
4. When finished, restore from your most recent backup.

If you have never synced your device with iTunes

Connecting the device may result in this error message: "iTunes could not connect to the [device] because it is locked with a passcode. You must enter your passcode on the [device] before it can be used with iTunes."

1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
3. While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button.
5. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.

If you don't have access to a computer

If you are using Find My iPhone, you can use Remote Wipe to restore your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode.

The safe way to use one Internet password

The safe way to use one Internet password
February 25, 2010

(PhysOrg.com) -- A little-used Internet authentication system from the 1980s could provide the answer for enabling web users to securely log in only once per Internet session, a Queensland University of Technology researcher has found.

PhD researcher Suriadi, from QUT's Information Security Institute, said a secure single-sign on system was more than simply using the same password for multiple accounts.

Mr Suriadi said any future single-sign on systems, which could potentially give web users access to a multitude of accounts, including email, bank and shopping, would require extreme privacy to avoid information spies and account hackers.

"Single-sign on systems are already being used by organisations," he said.

"For example, a bank could link their Internet banking site to an online trading site, thus relieving users from having to perform an extra log in step.

"However, if one of the parties is compromised, for example by a virus, a 'denial of service' attack or insecure set-up, it puts all the user's linked accounts at risk."

Mr Suriadi said his research investigated a little-used "anonymous credential system" which dates back to the 1980s, but recently received renewed interest from the research community.

"Using this credential system, we could enhance the security and privacy of a single sign-on system," he said.

"The system works by revealing as little information about who you are as necessary for logging into an account, therefore allowing you to remain anonymous.

"This way, a company wouldn't be able to track your shopping habits and target spam or marketing at you. This method could also confirm you are over 18 and not reveal your birthday."

Mr Suriadi said a single sign-on system backed by the anonymous credential system required the cooperation of businesses and organisations to enable it.

"One use of this could be for the research community, with online libraries and databases applying the anonymous credential system so that the privacy of researchers can be preserved," he said.

"This would be useful for people researching sensitive issues."

Mr Suriadi said for the purposes of accountability, such a system would also allow authorities to revoke users' anonymity in cases of illegal activity.
