Multi messaging app WhatsApp has rolled out the fingerprint feature for its Android Beta users. It is available on the Android Beta version 2.19.221.
As mentioned, now WhatsApp Android users can unlock the app through the fingerprint sensor. According to WABetainfo, users will need to use the fingerprint to open WhatsApp while they can still receive or reject calls if the app is locked in the background. It is disabled by default, to enable WhatsApp’s fingerprint sensor on your phone, you need to go to WhatsApp Settings > Account > Privacy > Fingerprint lock.
There are three options for automatically lock to choose from immediately, after 1 minute, and after 30 minutes. Users can choose from these options according to their preference.
WhatsApp has already introduced the fingerprint feature for the iPhone users earlier this year. To enable WhatsApp’s fingerprint sensor on your iPhone, you need to open the WhatsApp > Settings > choose Account and tap on Privacy > toggle the button to enable screen lock.
WABetaInfo spotted this feature first, and says, “I can say that it's safe for your privacy to enable the Fingerprint lock feature because WhatsApp, like any other app, cannot access to your fingerprint data: the authentication process is managed by the Android system: WhatsApp uses official Android APIs, so no information is sent to WhatsApp/Facebook Server.”
Furthermore, if you cannot gain access to the new fingerprint Beta version, you could alternatively download the APK via APK Mirror.
