Hi. I am new to this forum. Before I explain my post, its worth mentioning that I have several brain related problems. So kindly dont give advices about repost and read the forum. Because I cant, its alot. I need an app for my galaxy note 5 with lollipop currently, which could let me loging into apps by fingerprint. Like if I want to login to facebook app, I just swipe my thumb and it log me in. Does an app like that exist? I'll really appreciate your help. I already googled as much as possible for my eyes, but couldn't find any. Thanks. Best.
