Two Factor Authentication Service Inc.

Frequently Asked Questions (FAQ)

If you’re not completely sure your devices or ones used by your sub-users are completely free of keyloggers and viruses, then it is a great solution. Without the token generated by your smartphone, any password discovery attempt will be useless with 2FAS plugin.
No, it is not necessary. The 2FAS plugin determines whether or not the user is required to enter a token as an additional form of authentication.
The most common way to use the 2FAS plugin is to configure your smartphone to generate tokens. We recommend installing 2FAS Authenticator but you can download any Time-based One-time Password (TOTP) app (e.g. Google Authenticator, Authy, FreeOTP, etc.). 2FAS Authenticator app largely speeds up the verification process and makes it much more convenient, as it enables you to log in by one click on your mobile, without the need of retyping the code.
Yes, you can; however, it isn’t as safe as using your smartphone. The main idea of the two-factor authentication is based on using different devices or channels, which can verify a user. When you are using a browser extension, then you are not protected from malware or viruses, which can catch your token.
In general, our plugin offers four authentication methods: TOTP app, offline code, text message, and an automated voice call. TOTP is the primary method and the other are backup methods. You can use them if you don’t have access to a mobile application.
It is completely free if you’re using tokens (TOTP, e.g. for Google Authenticator app). If you’d like to use text messaging or voice call, you need to create an account at 2fas.com and see our pricing, since prices vary depending on cell phone carriers. We charge only for the messages that are sent (authentication).
