For various reasons, sometimes we find ourselves in need of lending our smartphone to another person, which exposes our personal information such as photos or other data that we have in the applications. One of the options we have to protect our privacy is block access to applications, a relatively simple but little known task.
Next we will explain some methods for iOS and Android how to put a password to an application and thus be able to block your access for those who are using our smartphone in another activity.
How to password-block access to applications on iPhone and iPad with iOS 12
We start with iOS, which is the simplest method but interestingly it is not designed with the purpose of blocking access to applications. Apple does not allow third-party applications to perform this function., and fortunately there is a native method of the operating system that will serve us for this purpose.
We refer to 'Use time', the function that are iOS 12 with the aim of keeping track of the time we spend looking at the iPhone and each application that we have installed. This option is the one that will help us to block applications and only access them if we have a PIN, which is not the same as that used to unlock the phone.
Before we start, and if they haven't been activated yet, we need enable the code that we will use for 'Usage Time'. For this, we will go to 'Settings> Time in Use', at the bottom we will choose the option 'Use code for time of use' and we will follow the instructions to choose a four-digit PIN.
Once we have the PIN, we will have two options: block all applications or categories; or choose individual applications. Let's look at each case.
Block all apps or categories
- Settings> Time in Use
- Select 'App usage limits'
- Add limit
- Select apps (here we can choose all the apps or each of the available categories)
- We choose 1 minute> Add
With this, all applications will be blocked after one minute of use, and to be able to access them we will need to enter the PIN that we selected previously. The advantage of this method is that we don't have to choose application by application, since we can block all with one touch.
Block individual applications
- Settings> Time in Use
- Select the name of our device (top)
- We deploy the applications and choose the one we want to block
- Add limit (at the bottom)
- We choose 1 minute> Add
In case the application we want to block does not appear, on the second screen we will choose the option 'Last 7 days' at the top, and in the 'Show more' apps section, so that we will be displaying all the apps in order of greatest use.
Once we have blocked an app, This will appear with an hourglass next to the name and when selected, it will show us a screen that will tell us that we have reached the time limit. To unlock it, we only have to select 'Ask for more time' and enter the code we choose for 'Time of Use'.
How to password-block access to Android applications
In the case of Android, unlike iOS, we don't have a native operating system method to block applications, although there are options such as 'Fix screen' that serve to block access to any other application or area of ??the phone. That is to say, the 'Fix screen' will make us remain in the screen or app that we choose and we can only leave after entering the PIN of our smartphone.
Because of the above, and which is an advantage over iOS, here we can rely on third party applications They do the task of blocking our applications with passwords in an easy way. In addition, some offer other additional security options that might be interesting. Let's see some of these applications.
Norton App Lock
Norton App Lock is by far the best option to put a password to our applications. Its function is as is to protect unwanted access to our apps or private files. It allows us to choose to block access to all applications or individually, and the security system is based on either a four-digit PIN, an alphanumeric password or an on-screen pattern. The application is free and compatible as of Android 4.1.

AppLock is another app that serves to block access to our applications through password, although in this case also integrates a lot of additional options how to restrict access to calls or messages, we can even choose that some images are not displayed in our gallery. The app is free and compatible as of Android 4.0.

And we come to one of those apps that do everything, since Security Master is announced as an antivirus that includes an applocker, that is, an option to set a password to our applications. It can be said that it is the most complete app but also the most complex, since its large number of options can be overwhelming for those who only seek to set their apps password.

Native options for Huawei and Samsung
Finally, it should be noted that lHuawei and Samsung smartphones have native options to create secure or private folders, in which we can put applications that we do not want to be accessible to all who touch our phone. It is like an additional layer of security that can be configured directly on the device.
In the case of Samsung it is called 'Secure Folder' and it is a folder whose access is restricted by password, and not even be visible if we access from a PC using a USB cable. Here we can put any application, choose the method of unlocking, if we do not want to receive or that notifications of these apps and other security options are visible.
For Huawei the option is known as PrivateSpace and is integrated into EMUI, so it is also available for Honor devices. It is very similar to Samsung's option, only in this case it is not a folder, but a private "space" where we will isolate images, data and applications. It is like having a second user and to access here we will simply have to configure a different finger to use it on the lock screen, which will give us access to this private area.
