webOTP - Web-based Encrypted One Time Password Generator

Download

Release

Features

• AES-GCM encrypted vaults with PBKDF2 key derivation and automatic migration from legacy vault records
• TOTP and HOTP QR import, drag-and-drop QR scanning, live codes, countdowns, search, and one-key copying
• Browser-page OTP detection and autofill through a Manifest V3 service worker
• Encrypted and decrypted vault export, local accounts, and configurable locking preferences

The extension uses Chrome Manifest V3 APIs and requires the storage, contextMenus, and active-tab permissions listed in src/manifest.json.

Manual Installation

1. Download this zip file
2. Extract the webOTP-main.zip file
3. Open chrome://extensions
4. Turn on developer mode
5. Click Load Unpacked
6. Select webOTP-main/src folder

Development

The project is incrementally migrating to TypeScript and Deno. Install Deno, then run:

• deno task build to copy the existing extension into dist/ and bundle the new TypeScript library.
• deno task test to run the library tests.
• deno task licenses to regenerate open-source-components.md while preserving manual logo and icon attribution.
• deno fmt --check to verify formatting.
• deno lint to run static checks.
• deno test to run the test suite.

The existing src/ directory remains loadable as an unpacked extension during the migration. The generated dist/ directory is also loadable as an unpacked extension after a build.
