Oleauth

OleAuth is a simple, secure authenticator app that generates one-time codes (OTP) for two-factor authentication. No account or login required—everything stays on your device.

► OFFLINE & PRIVATE
• Works fully offline. No internet needed to generate codes.
• No sign-up, no email, no cloud. Your secrets never leave your device.
• Data is stored locally and is removed if you uninstall the app.

► EASY SETUP
• Add accounts by scanning a QR code or entering a setup key manually.
• Supports both time-based (TOTP) and counter-based (HOTP) codes.
• Edit labels and delete or reorder accounts anytime.

► SECURE BY DESIGN
• Secrets are stored using your device’s secure storage (Android Keystore).
• Optional screenshot blocking to keep codes private.
• Copy codes to clipboard; clipboard is cleared automatically after 30 seconds.

► BUILT FOR DAILY USE
• Clear countdown so you know when the next code is ready.
• Search your accounts quickly.
• Light and dark themes with system option.
• Notifications when a new app version is available.

OleAuth follows standard OTP protocols (RFC 6238 and RFC 4226) and is compatible with services that work with apps like Google Authenticator. Use it for work, email, social accounts, or any service that supports authenticator apps.

No account. No tracking. Just your codes, on your device.
