Okto Authenticator

About

Okto Authenticator — a fast, secure, and privacy-friendly two-factor authentication extension for Chrome.

 TOTP CODE GENERATOR
Generate time-based one-time passwords (TOTP) for all your accounts — Gmail, GitHub, Binance, Discord, and more. Add accounts by scanning a QR code or entering the secret key manually. Your accounts are stored locally on your device and never leave your browser.

 PHISHING PROTECTION
Okto actively monitors the sites you visit and warns you before a known phishing page can steal your credentials. When a dangerous site is detected, a full-screen warning is shown immediately — before the page even loads.

The phishing blocklist is automatically updated in the background every hour, so you're always protected against the latest threats.

✅ KEY FEATURES
• Generate TOTP 2FA codes for unlimited accounts
• Scan QR codes directly from images or your screen
• Real-time phishing site detection on every page you visit
• Hourly automatic blocklist updates — no action required
• 100% local storage — your secrets never leave your device
• No account, no sign-up, no tracking

🔒 PRIVACY FIRST
Okto does not collect, transmit, or store any personally identifiable information. The only data sent to the server is an anonymous installation ID used solely for blocklist delivery. No passwords, no TOTP secrets, no browsing history ever leave your device.
