### 1/5 — Authenticator App

*2023-04-18*

This App is THE WORST. I paid for it. Set up investments for daily trading. The app stopped working 10 days later. I am now locked out of my investments and am losing money daily due to not being able to access. Now attempting to get back into my investments via admin. Emailed creator of app multiple times with no answer. Just filed fraud claims. Beware: Stay AWAY from this authenticator app. Tran Minh looks to be the creator. I will NEVER use one of his apps again.
