For a free variant look here:
I made securelock because all the flows in the community that have security features were to be honest, not well made, lacking, not fault tolerant, or made with mistakes. As a bonus mine seems to be the only flow that's modular and you can easily add your own pieces to it.
Has many features:
-View last image on successful login.
-Email yourself the image with location.
-Remotely lock the device via text or Android wear notification.
-Text to speech messageon failed login
-Locks with device admin on failed login disabling fingerprint until you login.
Check the roadmap for planned features.
I always listen to ideas, if there's a feature you want, comment and I'll look into making it a thing.
Removed save setting in favor of simpler asking if you want to save it when you login.
Fixed grammar/spelling errors
Fixed newly created bugs
Added 3 fail fault tolerance for the lock.
Removed blocks from unfinished features
Playback audio file or recording on failed login.
Change lock wallpaper to either image of choice or picture taken
