Features & Capabilities

With Chiff's browser extension you can securely connect your Chiff app to your browser by scanning a QR-code. Whenever you want to log in to a website, you receive a push message on your phone that you authorize with TouchID, FaceID or a passcode. Chiff sends your credentials to your browser and automatically logs you in. You don't need to remember a single password anymore!

This extension is used in conjunction with the Chiff app. You can download the Chiff app in Apple's App Store or Google's Play Store.

Why Chiff?

Since the start of the Internet we've been logging in with passwords, but this is a growing problem. To be safe, we must use unique and complex passwords for each website, which we also have to change regularly. But why do we still log in with passwords, while we can unlock our mobile phones with just our fingerprint? It's time for a different way of logging in. It's time for Chiff.

What is Chiff?

Log in to every website with your fingerprint or face by authorizing a push notification on your phone.
Free for personal use.
Use long, complex and unique passwords for all accounts.
Passwords are securely stored on your phone.
Supports multiple authentication methods such as One Time Passwords (OTP) and WebAuthn.
The new way of logging in.

Security is our top priority. The security of the app and extension have been extensively tested by an independent third party. Moreover, Chiff never has access to your sensitive data. Your passwords are securely stored on your phone and every message between the app and browser is end-to-end encrypted, so even we cannot decrypt it. Besides being very secure, it makes Chiff also privacy-friendly.

This project has received funding from the European Union's Horizon2020 research and innovation programme under the NGI_TRUST grant agreement no 825618.

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.

Chiff requires some sensitive permissions that could impact your browser and data security. 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.

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