Opty is a fully offline TOTP authenticator built for people who refuse to compromise on privacy. There is no cloud, no backend, no syncing, and no internet permission. Every authentication code is generated and stored only on your device in encrypted form. Nothing is uploaded. Nothing is shared. Ever. Most authenticator apps depend on servers, analytics, and online services. Opty eliminates all of that. With zero network access, your data remains physically isolated on your phone, making remote breaches and mass data leaks impossible by design. Core Principles: 100% offline operation No backend, no cloud, no syncing No internet permission required Encrypted local storage Zero tracking, zero analytics No accounts, no data collection How It Protects You: All TOTP secrets are stored locally using strong encryption Codes are generated on-device only No third-party SDKs that track or transmit data Even we cannot see your codes Designed for Reliability Opty works anytime, anywhere — even in airplane mode. Whether you’re traveling, in low-network zones, or simply prefer keeping your security tools offline, Opty keeps your access uninterrupted. Who It’s For: Privacy-focused users Developers and security professionals Anyone who wants full ownership of their authentication data With Opty, your phone becomes your authenticator — not a gateway to someone else’s servers. Your codes. Your device. Your control.
