How to put a password to your applications so that nobody can see their content

21 mayo, 2021

Everyone deserves a little space private and secure, and our phones often take on that role. The problem is that no matter how private our phone seems to us most of the time, in an oversight of a couple of seconds this privacy can be screwed up.

If you would rather keep some apps for your Eyes Only, there are a good number of options and specialized applications to achieve this, from lock screens with added security to passwords for applications or decoys to divert attention.

1. Fortify the gate

Your android device locks automatically after a period of inactivity ranging from 15 seconds to 10 minutes, so there is a good chance that the lock screen be the first thing an intruder sees.

Although it seems obvious, adding any type of security to the lock screen will make it difficult for other people to see what you do not want them to see. About security in particular is up to you, but keep in mind that it is not too difficult for someone close to you see your PIN code or pattern on an oversight and remember it. If you want to be safe, use more secure methods like fingerprint or password.

In this regard, I would recommend using the lock screen functionality of your mobile whenever possible, although if for some reason it does not convince you, options in Google Play are not lacking. As long as you focus on well-known names like GO Locker, Solo Locker, or Locker Master, you shouldn’t have a problem.


These third-party screen lockers they rarely give you more securityInstead, they focus more on giving you more customization options and improving aesthetics, but they are an option to take into account if, for whatever reason, your phone’s lock lacks options.

2. Limit what you show

Has it ever happened to you that you lend your mobile one second to show a photo and the second the other person starts look at all your gallery of photos and applications? Regardless of the other person’s bad manners, there are several software solutions that can help you.

The first of all is Pin an app. This feature was introduced with Lollipop three years ago, but unfortunately some manufacturers forget to include it, or hide it in the options. To activate it you must go to Settings – Security – Fix windows. After doing so, you should see an icon with a Pin in the recent apps list.


When a window is fixed, can’t change app and you don’t get notifications from other apps either. It is possible to unlock the window with a long press on the recent / menu button, but you can configure it in the settings so that it is necessary to enter the pattern or PIN code before this happens.

Of course, this mode does not prevent the other person explore your entire gallery after showing a photoas it is the same application. For those cases there are specific applications such as Stop Swippin !. This application requires an additional step: you must select the photos that you want to be accessible, send them to the application and set the window.

It is not the most practical or fastest method of showing a photo to a friend, but if you really want to physically prevent them from seeing the rest of the items in your gallery, you need to take drastic measures like the previous one before leaving your mobile in the hands of someone else.

3. Divert attention

Do you have applications installed on your mobile that you are not proud of? If you have installed Toilet Simulator and you think that your acquaintances will laugh at you for it (and with good reason) you have several options so that it goes unnoticed.

Some launchers allow you hide apps. Hiding an application is not the same as disabling it: you can still start them, but they are in a semi-hidden menu called Hidden Applications. Other launchers like Nova Launcher go a step further and allow you rename them and change their icon.

In Nova Launcher, with a long press on an application you can Edit. Unchecking the boxes will will hide from the app list, and you can also change your name and icon, to choose between several custom icons and those of other applications.


Other applications such as Icon Changer Free or LINE Deco also allow you create application shortcuts with different icons and name, but if your launcher can’t hide the app from the app drawer, the lure has limited utility.

4. Protect specific applications

The highest and last level of security means protecting specific applications so that they cannot be started by anyone. Here the first thing you have to do is check that the application does not already have this option, as is the case with Telegram. In this case, the option is in your Settings – Privacy and security – Access code.

Of course, not all applications include code control, and once again third-party applications are here to help you out. There is a lot of “App Lockers“On Google Play, some well-known developers like Cheetah Mobile, but considering the background, it is more advisable to trust more well-known names like Norton App Lock.

Norton App Lock needs accessibility permission to know when an app has started, but is otherwise quite easy to use. First, you choose a secret pattern and then you choose what applications do you want to protect marking them with a padlock.


From then on, each time the application is launched or displayed on the screen, Norton App Lock will be displayed in full screen ** asking you to enter the unlock PIN **. If you don’t enter it, it returns to the launcher.

One point in favor of Norton App Lock is that it is smart enough to ask you for the pattern again before you can go to Android’s Accessibility options and disable it. It can also be set as Device administrator, to protect its use even more.
