Features & Capabilities

You no longer need to use your phone to authenticate. This 2FA TOTP authenticator extension gives you 2-step verification codes directly in your browser, and the added layer of security that TypingDNA’s AI-based typing biometrics authentication provides (optional).

Key features:

Verification TOTP (time-based OTP) codes in your browser
One-click to copy verification codes
Secret keys vault functionality
Scan QR codes directly from websites
Show QR codes for quick scan
Import/Export codes to/from file
AI-based typing biometrics authentication as a security layer (Premium only)

How the TypingDNA authentication works:

Type your email and secure pharse (or optionally, a password)
Typing pattern authentication happens at TypingDNA.com in the background
Once your typing pattern is verified, a master encryption key is released and unlocks your security codes locally in order to generate your TOTP 2FA codes right in your browser

One-click to paste codes: You can get your 2FA codes by simply selecting an account from the list, copy-pasting the OTP code directly into the webpage or other apps.

Vault and authenticator, 2 in 1 Keep all your secret keys safe. Generate your 2FA TOTP codes whenever needed and also reproduce the initial QR code for a quick phone rescan. This feature is not available with other authenticators, not even with phone based ones (like Google Authenticator).

TypingDNA’s typing biometrics technology performs authentication as individuals simply type on their keyboard. By using proprietary artificial intelligence technology we analyze an individual's unique typing pattern and match it against previous recordings (for Secured accounts/Premium only).

Can I use the 2FA Authenticator completely Free? Yes! You can use the 2FA Authenticator for Free. The main difference between Free and Premium versions is that the Free version is not secured (like all other TOTP authenticators on Chrome store). Therefore we don't recommend it for sensitive work and personal accounts. However, our Premium version comes with the secured experience. That being said, the Free version experience is faster, as it doesn't require login. Many users prefer this experience.

Is 2FA Authenticator Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

2FA Authenticator requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

2FA Authenticator may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
