⚡ Fast 2FA Auto-Fill & TOTP Authenticator Stop switching between authenticator apps, browser tabs and spreadsheets just to find the correct verification code. 2FA Auto Fill generates 6-digit TOTP verification codes locally in your browser and automatically fills supported authentication fields. It can detect supported Facebook login and Business Manager verification pages and fill the current code automatically. You remain in control: the extension fills the verification code only. It does not automatically click Continue, Confirm or submit login forms. --- 💡 KEY FEATURES ■ Automatic 2FA Code Filling • Smart Detection: Detects supported authentication and security verification fields. • Automatic TOTP Fill: Generates the current 6-digit code locally and fills it into the supported verification field. • User-Controlled Login: The extension never automatically submits forms or confirms login actions. ■ Local TOTP Generation • Local Code Generation: Uses the standard Time-Based One-Time Password algorithm to generate codes directly in your browser. • Local Account Storage: Secret keys, account names, favorites, ordering and settings are stored locally in the current browser profile. • No Secret Uploads: Your authentication secrets and generated codes are not sent to our servers or third-party analytics services. • Important: Regular extension storage is not protected by the backup-file password.
