[Android Apps and Games] Andrew-X:
Hello guys!

Tired of typing your password each time you want to unlock your computer?

After months of work, I have finally launched my project, Remote Fingerprint Unlock, which allows you to remotely wake up and unlock your Windows computer with a single fingerprint tap!

Features:

• Simple, user-friendly UI

• Secure

• Local/Microsoft/Domain** accounts supported

• 3 app themes - Light, Dark, Black (AMOLED)

• Wi-Fi/Bluetooth/Wi-Fi Tethering support

**1.2.0 version of the Windows module required. Usage: when adding an account using the Android app, simply add the full name of the account, including the domain, separated by a slash ( ‘\’ ). For example: test\account.name

PRO features:

• Ads removal

• Unlimited computers and account per computer

• Wake-On-Lan

• Unlock widgets - can be linked to any account, useful if you have more computers that you want to unlock

• Launcher shortcuts - same as widgets, can be used by long-tapping the app icon or can be pinned like any other launcher shortcut

With that being said, here is the link to the app: Google Play (recommended) or check attached .apk file.

The Windows module, found at http://bit.ly/2Q4YoUP is required for the app to work. Please be sure to check for updates from time to time as they can contain fixes and add new features. The changelog can be found at the same link.

The app was featured on XDA News, thanks to the guys at XDA! :highfive: So, if you think that you need such a tool, be sure to give it a try!

Lastly, any question that you may have, be it about how the app works, how to use it or if you are just leaving feedback, don't hesitate posting it here! Thanks for taking the time to check the app!

Security

The communication between modules is secured using TLS (SSL). The accounts are stored on your computer as they are required when unlocking. However, they are encrypted using a key that is generated based on your fingerprint. As per this article, the generated key is backed by a Trusted Execution Environment, which prevents an attacker from gaining access to the key even if he had compromised the kernel. In other words, only the enrolled fingerprints on your phone can access the key. If you do uninstall, reset your app or even if you change one of your registered fingerprints, the file where the accounts are stored is lost forever and you will need to reconfigure your accounts.

Lastly, research has been done to ensure that, even locally, your accounts are as safe as possible. No password is stored in-app and everything is done locally (between the app and the Windows module) and I'm not, in any way, shape or form, sending through the Internet or seeing anything that you type in-app.

Basic troubleshooting

If you cannot find you computer in the Scan menu, please check the following:

Be sure that the module is present on your logon screen. For example, on Windows 10, you should see it on the lower left corner of the screen. If you installed the program and it still isn’t present, please leave a reply, send me a PM or an email.

If you have a different firewall than Windows Firewall, please be sure that you have allowed all incoming and outgoing traffic on both TCP and UDP for LogonUI.exe process, found in C:\Windows\System32.

Be sure that both your computer and your smartphone are connected to the same network which assigns IP addresses on the same subnet. For example, both devices should have an IP starting with the same subnet prefix: 192.168.1.

If you have blocked ports on your network, be sure to allow port 4009 on both TCP and UDP for the app to function correctly.

If you added an account but unlocking does not work, please check the following:

If you are using a Microsoft account: if you tried adding an account, used your email address and it does not work, please update the Windows module to at least 1.0.2, which supports logging in a user using the displayed account name on the lockscreen. When adding an account in-app, try again by using the displayed name of that Microsoft account (the First and Last names).

If you are using a local account on Windows Vista or 7, you may have changed your account name in the past. Internally, Windows does not change the username so you need to type in the original username.

If you can’t remember it, just open a Command Prompt and type 'whoami’. The username that will be displayed is the one that the app will need.

You can also check how your personal user folder is called. It can be found in C:\Users.

On Windows 8 and 10, have at least the 1.0.2 version installed and simply add an account using the displayed name on the lockscreen.

Setting up/Testing Wake On Lan (PRO feature)

To enable WoL on your computer, you can follow the steps here. To enable WoL on your computer, follow the first part. After that, you can continue with the same tutorial if you have another computer available, or you can download this app on your Android phone to test it.

To send the WoL signal using the app, simply go to the saved computers, tap on the desired computer, tick Send WoL-Packet and Save. There is no need to configure anything as your MAC address is automatically detected when you add your computer. The wake-up signal will now be sent each time you unlock one of the accounts on that PC.

Take into consideration that on some computers, you may also need to enable WoL in your BIOS settings and that it may work only on certain states like being fully shut down, hibernated or sleeping. There is nothing I can do about it, unfortunately, as it depends on your PC. Thanks for understanding!
