Authium is the easiest way to manage and retrieve two-factor authentication (MFA) codes on desktop for developers and teams. Built for creators who lose focus context-switching to mobile devices 15+ times a day, Authium removes login friction using Login Copilot—a floating interactive chip that overlays OTP fields to autofill codes in one click. Unlike phone-based authenticators, Authium keeps codes native to your desktop browser with zero-knowledge AES-256 local encryption. You can import active `.env` secret keys in seconds, share credentials securely via E2EE Team Vaults without security exposure, and preserve your deep coding state. We built Authium because we were tired of phone-grabbing interruptions while coding. It is now used by over 50,000 developers to log in instantly.
