Very useful app.
I use this app to protect my account and messages. Never feel so secure like now.

Rue206 ,


Wasted a lot of precious time!!! Followed the instructions but could not scan the QR code from the application I was using and could not figure out how to enter a shared secret. Tried repeatedly but couldn’t get it the QR Code to scan and no instructions available regarding shared secrets.
