In-browser One-Time Password (OTP) authenticator for two-factor authentication (2FA)

Helps users manage and generate time-based (TOTP) and HMAC-based (HOTP) one-time passwords securely within the browser, serving as an alternative to standalone authenticator apps like Google Authenticator.

User installs extension -> Sets a master password to encrypt data -> Adds accounts by scanning QR codes or importing OTP URLs -> Extension generates time-based codes in the popup -> User can copy or autofill codes into login forms -> Optional: Sync data to cloud backup services for cross-device access

Target users: Developers & IT professionals / Everyday users securing their accounts / Anyone using 2-factor authentication (2FA)

The extension is heavily obfuscated/minified in dist/*.js files, making detailed code analysis difficult. However, keyword searches for paid/login indicators were exhaustive and negative.
The extension uses 'identity' permission and has OAuth2 configuration, but this is for optional cloud backup, not mandatory login.
No web store reviews or detailed pricing information was available to cross-reference, but code analysis is definitive.

Monetization

No paid features detected

No evidence of paid features, subscriptions, or in-app purchases. The extension appears to be completely free. There are no references to premium plans, upgrade prompts, payment gateways, or feature gating based on payment status in the source code.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local OTP authenticator. It does not require a user account to function. The core workflow of generating TOTP/HOTP codes works entirely offline using local storage. While it offers optional cloud backup (Google Drive, Dropbox, OneDrive) which requires signing into those specific services, the extension itself does not require login to use its primary features.
