## What it is
A browser extension that generates two-factor authentication (2FA) codes, acting as a software TOTP authenticator. It is available for Chrome, Firefox, Edge, and Safari, with support for encrypted backups and account import/export.

## Use cases
- generate 2fa codes in my browser
- replace google authenticator with a browser extension
- store totp tokens in chrome or firefox
- back up and restore two-factor accounts
- get one-time passwords without a phone app

## When to choose
- you want 2FA codes accessible directly in your browser
- you need a free, open-source authenticator with encrypted cloud backup options
- you use Chrome, Firefox, Edge, or Safari and want cross-browser support

## When to avoid
- you need hardware-token-backed or offline-only 2FA on mobile
- you prefer keeping TOTP secrets out of the browser for security reasons
- you need official support for the Safari edition

## Facets
- artifact type: plugin
- maturity: active
- function: auth, security, cryptography
- domain: security, privacy, browser-extensions, developer-tools
- platform: browser-extension, browser, cross-platform
