How to Unlock your PC with your Android Smartphone


Hey, guys, this is Ashish from GadgetRaja team, and today I just want to share a quick tutorial that I’m sure you will find quite useful.

First and foremost, this article is not sponsored by any company or product. What I’m going to be sharing today in this guide is what I use on a daily basis and what I do to improve the security of my personal computer.

Use your Android Phone to Unlock your PC

In this guide, I will be showing you how you can use the fingerprint sensor on your Android phone to unlock or wake up your PC. The app I am going to use is Remote Fingerprint Unlock, and you can download and use most of its features for free.

It allows you to set up and connect your Android device to multiple computers and use the fingerprint sensor to unlock them. I have been using the app with my Asus laptop and custom PC for the last six months, and I have nothing but only great things to talk about it.

This app does have a professional version which will cost you $1.99 but then will unlock various pro features. Personally, I think it is well worth the price.

Features of Remote Fingerprint Unlock App

Firstly, you can connect multiple computers to one Android device. You also have the option to link various accounts on your computer with your phone. I think its a great feature as now you have to remember passwords of all your accounts on your computer.

Secondly, there is an option called “wake on LAN.” You can use this option to wake up or unlock your ethernet connected computer.

Thirdly, the app generates custom widgets for every account or pc your connection with it. You can drag and add these widgets to the home screen of your Android device for easy access and easy unlocking.

Finally, you won’t have to handle all sorts of advertisements. Additionally, you also get lifetime free updates.

Is It Safe?

Are you wondering whether the app is safe or not? In my opinion, it definitely is. All of the data that get sent from your phone over wifi to your computer is encrypted.

Furthermore, the app doesn’t store any of your fingerprint data or passwords. So if in-case someone gets access to your smartphone and tries adding his or her fingerprint, the app will immediately know of all the changes and invalidate its previously set key automatically. This way, the intruder won’t be able to use the app to unlock your system.

In order to check future updates, I was just reading the official Google Play Store listing, and I found out that the developer is planning to add support for compatibility with Linux Operating System. The developer has also prepared a list of features for the next update. Below I have listed out some of the essential features coming up in the future updates.

  • You get the option to use your Android device to lock your system.
  • Bluetooth connectivity support.
  • Ability to configure the notifications when your PC unlocks or wakes up from sleep or hibernation mode.

So those are all of the things that the app offers, so now let’s focus on how to use this application.

Use Remote Fingerprint Unlock App

Unlike most of the apps with a similar feature, you will need to ROOT or ADB your device. But this app doesn’t need any root access or custom ROM to work.

First, you need is a smartphone with at least Android 6.0 or later version.

Second, you need a Windows computer (since it doesn’t support other operating systems right now).

If both requirements are satisfied, all you need to do next is to download and install the required applications.

First, you need to download the app from the play store and install it on your smartphone.

Finally, you also need to download, unzip, and then install the program on your computer. If you have 64-bit Windows OS installed then you must download the “” otherwise download the “” file.

Now once you have successfully downloaded and installed the program, you need to lock your PC.

In case you don’t know the shortcut, to lock your computer, you need to press Windows Key + L on your keyboard simultaneously.

Why Do I Need to Lock My Computer

The reason why you need to lock your PC is that your login screen is the only area where your computer will be able to communicate with the Windows program and Android app that you have installed.

Now coming back to the topic.

Your next step is then to open the Remote Fingerprint Unlock App on your phone and then click the scan option.

Now you need to pull to refresh the list and then you should be able to see your computer on the list ( please check the image attached above ). If your PC isn’t shown, then you can manually add it by entering your IP address.

If you want to unlock and wake up your Ethernet-connected computer, then you need to tap on the wake-on-LAN option. After you have selected your options press on the save button.

Then go into your accounts menu and then tap on “Add an Account” option. Now enter the login details of your Windows system, that is your username and the password of your desktop and then click on save button.

Now you will get a pop-up message asking you to confirm your session ID. Make sure that number shown on your phone matches to the number displayed on your desktop. If both the number matches click on the “proceed” option.

Finally, click on the “Menu ≡” and then click on the “Unlock” menu. Now you will get a screen asking you to scan your fingerprint, so do it, and you will see that your computer is now remotely unlocked.


If you want to unlock your Windows PC with your phone remotely, then you must check out this fantastic app. Its a light-weight (just 2.9MB), easy to use application which gives you access to additional pro-features for only $1.99.
