Using Screen Lock

We all know how unsafe it is to keep your phone screen unlocked. It is almost like leaving the front door to your apartment open for the intruders to come in. This is extremely dangerous since our phones nowadays are not just our calling devices but are reservoirs of personal data starting from important messages to bank codes. Hence it is of utmost importance to keep our phone screen locked in all instances. Here is how Apple lets you lock the screen of your iPhone.

Step 1 – Find the Power Button on Top or Side Edge of Your iPhone.

In order to unlock the screen, press the Home button just below the device screen. Give it a single Tap and wait for the screen to light up. Once the iPhone screen lights up you will be able to see a slider with an arrow to appear at the mid-bottom of the screen.

You will be able to unlock the screen only after applying the correct password.

How To Lock your iPhone Remotely 

When it comes to security, Apple tops the list with its security features that are exceptionally ahead of the others. One such remarkable feature of the iPhone is that it lets you lock your iPhone remotely in case of theft. The ‘Find my iPhone’ or ‘Lost Mode’ of the iPhone works exceptionally well in case your phone goes missing or falls into wrong hands. This feature lets you take complete control of your iPhone remotely so that you can instantly silence all notifications, alarms, and rings from incoming phone calls. Control Center will also be disabled, and even the Camera shortcut will shut down. This will render the phone useless and no one can use it on your behalf. Following are the steps by which you can enable the ‘Lost Mode’ of the iPhone.

Password Protect Your iPhone 

Only locking the screen of the iPhone is not enough since anyone can unlock the iPhone using the slider lock that doesn’t come with any encryption. Setting a password to protect the iPhone, therefore, means you can enable hardware-level encryption to protect all your data. Thus this will leave your device’s protection practically breakproof since no one would be able to access your private messages, photos, financial and health information without entering the series of numbers and characters that only you know. Before we get on to discuss the steps of how to set up, change and turn off the password, here are some instances where your device requires a password.

Notifications come all the time and hence your risk of exposing your private information happens all the time. Any passerby can look at the screen and read your message when a notification lights up the display. Although notifications are meant to give you updates and make your life easier by not having to unlock your phone to read a message, it indeed means anyone can read your notifications. This is especially problematic since notifications range from news, weather updates, important schedules to even emails and text messages that one can reply without even unlocking the iPhone. Fortunately, Apple has equipped its iOS devices with exceptional security features for blocking the lock screen notifications of various apps and controls.

The iPhone Today widget is one such handy widget that helps our daily life keep smooth paced. However, these widgets show notifications on the iPhone lock screen every now and then which means anyone else who has got your device can see your Today Widget notifications, thereby learning about your calendar and speed dial your contacts.

The iPhone’s Control center is a panel of settings and controls that do everything from toggling your airplane and Do Not Disturb modes to setting timers and turning your iPhone’s LED flash into a flashlight. Therefore, leaving Control Center enabled on your lock screen could allow an iPhone thief to put your stolen device into airplane mode, rendering your lost handset untraceable via Find My iPhone. Moreover, this control also has a Home Control that lets you control various devices present at your home. So restricting access to it should be taken in all seriousness.
