Dumb

This is such a waste of time. I already have my login to unlock my computer, and my login to get into my company access, then my login to Tekion, and then I have to come to this stupid app to get another code to put in. It’s not like we have nuclear launch codes inside of car deals. We all need to get off our high horses and start being normal.

FAQ

What does TOTP Authenticator do?

TOTP Authenticator generates one-time tokens (codes) that are used in conjunction with your password to provide an extra layer of security for your online accounts. This two-factor authentication (2FA) process helps protect your accounts from unauthorized access and hackers.

What are the key features of this app?

Key features include Cloud Sync for backing up your 2FA data, a Chrome Extension for easy desktop access to codes, support for both dark and light themes, multi-platform and multi-device syncing, unlimited account support, home screen widgets for quick access, and biometric app lock for enhanced privacy.

Is this app free to use?

The app offers a free version with core functionality. However, premium features like Cloud Sync and the Chrome Extension are available through in-app purchases, allowing you to enhance your experience and security further.

What devices is TOTP Authenticator compatible with?

The app supports multi-platform syncing, meaning you can export your data from one mobile platform and import it onto another. This allows for seamless usage across different mobile devices, and the Chrome extension extends its utility to desktop browsing.

What kind of accounts can I secure with this app?

This app works with the majority of services that offer 6-digit code-based 2FA, similar to Google Authenticator. This includes popular platforms like Google, Facebook, Fortnite, and Instagram, as well as many others that support two-step authentication.
