Features & Capabilities

The TOTP Chrome extension offers a secure, javascript-based Time-based One-Time Password (TOTP) generator that supports popular sites like Gmail, GitHub, and other services requiring two-factor authentication (2FA). It functions equivalently to Google's authenticator apps or the 'oathtool --totp' command, ensuring compatibility and reliability using the browser's native crypto API.

Unlike traditional TOTP apps, this extension does not send or retrieve data remotely, maintaining user privacy and security. It leverages the browser's built-in password manager to store TOTP keys securely, preventing access from malicious websites by isolating keys within the extension's unique URL namespace. Additionally, the extension avoids content scripts to prevent unauthorized code generation or autofill, further enhancing security. Users on Linux/X11 platforms should note a workaround related to clipboard operations due to system-level fixes.

User Reviews

Users appreciate TOTP's simplicity, lightweight design, and strong privacy features. It supports multiple keys and functions well with services like GitHub's two-factor authentication. However, a common drawback noted is the lack of automatic synchronization across different Firefox installations, requiring users to manually manage tokens through Firefox's password manager.

Pros

Supports multiple keys easily
Privacy-conscious and safer/private than using an app or online TOTP service
Simple and lightweight
Works well with GitHub's new 2FA requirement

Cons

Does not sync automatically across Firefox instances due to unique extension identifiers
Requires manual retrieval of tokens from the Firefox password manager for syncing

Is TOTP 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.

TOTP does not require any sensitive permissions.

Risk impact analysis details

Low This permission has no access or impact on the user's system or data, thus carrying no risk.

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.

TOTP has earned a fairly good reputation and likely can be trusted.
