An alphanumeric password would be the hardest one to crack for a third party especially a long password containing alphabets and numbers. To configure the alphanumeric password on iOS, launch Settings app from the Home screen of the device, and tap on Touch ID & Passcode. Then, enter your existing 4-digit or 6-digit passcode if you have configured one earlier on the iPad tablet and tap on next.
Then, iOS will land on the Change Passcode screen. Key in your existing passcode again upon prompt, tap on Passcode Options > Custom Alphanumeric Code, and enter a new alphanumeric password. Once you enter the new custom password, tap on Next in the upper right corner of the screen and key in the alphanumeric password once more for confirmation. In the next screen, tap on Done to configure the customized password in the iPad tablet or an iPhone.
In addition, the auto-lock feature on iOS would let you control how long you want the screen of either of the iOS devices to stay on when not in use. Launch the Settings app on iOS, tap on Display & Brightness, and choose Auto-Lock. Tap on the automatic lock duration you need for your iOS device – you can choose from 30 Seconds, 1 Minutes, 2 Minutes, 3 Minutes, 4 Minutes, and up to 5 Minutes. In fact, you can configure the auto-lock for 30 seconds so that device screen will go off quick when the device is not in use and thereby save battery. You can also choose the option Never, if you don’t want the iOS device’s screen to go off at all.
As for the device performance, how to avoid clogging of running apps on iOS is another one of those needs for most of us. The Apple Siri voice assistant gets instant responses to your queries and too much of that can clog your lock the screen. However, you can disable Apple Siri to keep her quiet when the device screen is locked. For that, open the Settings app from the Home screen, and tap on Touch ID & Passcode. Then, enter your new alphanumeric passcode and toggle the switch for Apple Siri to its Off position. The toggle for Apple Siri will grayed out when you disable the feature on your iPad.
