SecureGen

Open-source ESP32 hardware device combining a TOTP authenticator and offline password manager.

Physical productfreeglobal

Open-source firmware for LILYGO T-Display ESP32 boards that converts the hardware into a TOTP/HOTP authenticator and offline password manager, offering AES-256 encryption, BLE/USB HID typing, a local web management interface, and a Hidden Space for a second isolated vault. Distributed under an MIT license, it provides 2FA codes and stored-password typing without cloud dependency, intended for hobbyists and security-conscious users willing to flash compatible ESP32 hardware rather than use phone-based apps tied to a single internet-connected device.
