Simple Authenticator is a Chrome extension that generates Time-based One-Time Passwords (TOTP) for two-factor authentication.
This extension does NOT collect, transmit, or share any personal data with external servers.
All data (TOTP secret keys, account names, issuer names) is stored locally in your browser using Chrome's storage API. Your sensitive authentication data never leaves your device.
- storage: To save your TOTP accounts locally in Chrome
- activeTab: To auto-paste OTP codes to the current tab's login form
- scripting: To inject OTP codes into input fields for auto-fill functionality
This extension does not use any third-party services, analytics, or tracking.
All secret keys are stored only on your local device. We recommend regularly backing up your accounts using the export feature.
