Why you should never download this app!

I downloaded this app because I was offered free skins in Fortnite. Now I am permanently logged out of my epic games account because this worthless app won’t give me any codes to log into my account. I highly recommend that you don’t download this app. This app is a complete scam, you will most likely not be able to sign into any account that you link this app with. This app is an awful idea and awfully made.

Developer Response ,

This is a security app that allows you to protect your Internet accounts. It works perfectly with Google, Facebook, Amazon, Fortnite, and many many more. All you need is to scan the QR code from the service (i.e. Fortnite in your case), and you will see tokens. If you don't see any tokens that means you haven't linked your account properly or removed 2FAS app. As it is the security app, we don't keep any information from our users.
