### 3/5 — Useless

*2025-09-01*

Had no idea it would not support FIDO passkeys, only TOTP 2Fa via the nfc connection, and even then it would not read the drive at all. I know my phone supports it, so either the app or the drives fault.

### 1/5 — Scam

*2025-08-20*

Don’t even bother, it legit is just a scam and the product is also not good

### 5/5 — Works perfectly

*2024-12-31*

This is my 1st security key and I’m happy i chose Thetis

### 5/5 — Easy to use

*2024-11-20*

Good.

### 5/5 — Great Authenticator app with their security key

*2024-11-04*

After reading the setup guide, I realized this app isn’t for setting up their FIDO2 security keys but instead for configuring two-factor authentication. I successfully added my Gmail TOTP (the QR code provided by Google) to my security key using the app, and it works great!
