Trezur

Trezur is a fast, secure, and lightweight web application for generating TOTP and HOTP tokens. Designed with simplicity in mind, it provides a straightforward interface for managing two-factor authentication codes across all your online accounts.

Built as a web-based tool using Svelte, Trezur focuses on performance and security while remaining easy to use. It supports both time-based (TOTP) and counter-based (HOTP) one-time password generation, making it compatible with a wide range of services and authentication systems.

As an open-source alternative to proprietary apps like Google Authenticator and Microsoft Authenticator, Trezur gives users full visibility into how their authentication data is handled without requiring account creation or cloud dependencies.
