About this app

[Requirements]
- Android 8 (or later)
- QNAP NAS running QTS 5.1.0 (or later)

QNAP Authenticator is a free app that adds an extra layer of security to your accounts by using your mobile device to verify your login. You can authenticate your identity using 2-Step Verification or Passwordless Login and choose from multiple verification methods.

Major features of QNAP Authenticator:
- Supports 2-Step Verification and Passwordless Login
- Supports scanning a QR code to quickly add an account
- Supports the following verification methods:
 1.Login Approval: Approve a login request with just a tap
 2.QR Code: Scan a QR code to verify a login request
 3.Online Verification Code: Receive a code sent from your QNAP device for verification
 4.Time-based One-Time Password (TOTP): Generate a code automatically renewed for verification

Login Approval, QR Code, and Online Verification Code require a connection to your NAS, whereas TOTP can work offline. This method also supports verifying third-party accounts from Google, Microsoft, Facebook, GitHub, and other service providers that have implemented their authentication following the TOTP standard.

Would be better if the TOTP page was the landing page for the app on opening and not the account page. Or can the page order be customized?

Works fine but can you 1. Rename the app to QNap Authenticator to differentiate from all the other Authenticator apps on my phone; 2. Have the option to use a generic Authenticator app, like Microsoft or other. I don't need 10 Authenticator apps on my phone.
