## Description

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.

## Review summary

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
