Do you want to lock the Signal app on your Android phone to keep your privacy safe? This guide will teach you how to set a fingerprint lock on the Signal app on Android.
The signal is among the most used smartphone messaging programs, alongside Telegram, WhatsApp, and iMessage. The majority of mobile users prefer the rest of them since they are accessible on both Android and iOS, with the exception of Apple’s messaging service, which is only available on iPhones. The procedure for setting a screen lock is the same for iOS and Android, however, the PC versions of the software conspicuously lack this option. It is unknown when Signal will provide the functionality to its Windows and Mac clients.
One of the top instant messaging applications, Signal, offers end-to-end encryption. It also gives smartphone users the option to apply a screen lock to protect their privacy further. The function, which is accessible on both Android and iOS, locks the app so that no unauthorized user may view any of the messages by using the phone’s pin, passphrase, or biometric identification (fingerprint or Face ID). It just takes a few clicks to install a screen lock to Signal, and the procedure is quite simple.
