SecureFill Password Manager & Authenticator

Secure password manager with autofill, multi-account logins, TOTP/2FA authenticator, QR import, encrypted vault and backup.

SecureFill is a local-first password manager and TOTP/2FA authenticator for Chrome. Save multiple accounts for the same website, choose a default account for automatic filling, or switch to another saved account from the extension popup for the current tab. SecureFill supports common multi-step sign-in flows where a website asks for the username first, then the password, then an OTP code. KEY FEATURES • Multiple accounts per website • Default AutoFill account per site • Per-tab account switching from the extension popup • Username and password AutoFill • Multi-step login support • Optional TOTP/2FA per account • QR image, otpauth URI, and Base32 TOTP import • Click the OTP code to copy it • Individual Username / Password / OTP AutoFill controls per account • Encrypted local vault • Encrypted export/import backup • 15-minute, 1-hour, or 8-hour unlock duration • Automatic vault lock when the computer is locked • Unlock session ends when Chrome closes • 5 wrong Master Password attempts trigger a temporary 5-minute lockout • Optional Emergency Wipe after 10 consecutive wrong Master Password attempts PRIVACY & SECURITY SecureFill does not use a developer-operated cloud service and does not use remote code. Authentication data is stored locally in the Chrome profile. Passwords, usernames/account details, and TOTP secrets are stored inside the encrypted vault. The extension only requests access to HTTPS sites that the user explicitly configures. When the vault is unlocked, temporary unlock key material is kept only in Chrome session-scoped extension storage and extension memory so Manifest V3 service-worker suspension does not immediately end the session. It is removed when the vault locks and does not persist after Chrome closes. SecureFill does not auto-submit login forms. The user remains in control of the final sign-in action. WHAT'S NEW IN v6.2.5 • Redesigned Sites & Accounts management • Multiple accounts per website • Per-account Username / Password / OTP switches • Password-only accounts are supported; TOTP is optional • Account switching for the current tab from the popup • Multi-step username → password → OTP login support • Current-site accounts are shown first in the popup • Modern fixed-width popup scrollbar to prevent layout shifting • 5-attempt temporary unlock lockout • Optional 10-attempt Emergency Wipe • Updated store description and privacy disclosures
