OOSOFT

OOSOFT 2FA Security adds robust two-factor authentication to your WordPress site. Protect every login with a second verification step using a TOTP authenticator app (Google Authenticator, Authy, etc.) or a one-time code sent to your email address.
Key Features:
<ul>
<li>TOTP Authenticator App — compatible with Google Authenticator, Authy, Microsoft Authenticator, and any RFC 6238-compliant app.</li>
<li>Email OTP — sends a time-limited one-time code to the user’s registered email address.</li>
<li>Backup Codes — generate single-use recovery codes so users are never locked out.</li>
<li>Role-Based Enforcement — require 2FA for specific roles (e.g. administrators) while leaving it optional for others.</li>
<li>Rate Limiting — brute-force protection with configurable attempt limits and lockout periods.</li>
<li>Security Logs — detailed event logging with filterable admin view and automatic pruning.</li>
<li>Encrypted Secret Storage — TOTP secrets are encrypted at rest using libsodium (preferred) or AES-256-GCM/CBC via OpenSSL.</li>
<li>HKDF Key Derivation — encryption keys are derived from your WordPress secret keys; no raw key material is stored.</li>
</ul>

<h3>External services</h3>
This plugin uses a third-party service to generate QR codes during the TOTP authenticator app setup process.
<h4>QR Server API</h4>
When a user chooses the “Authenticator App” method during 2FA setup, the plugin generates a QR code image via the QR Server API. This QR code contains the TOTP secret URI (which includes the site name, user email, and secret key) so the user can scan it with their authenticator app.
<ul>
<li>What data is sent: A TOTP provisioning URI containing the site name, user email address, and a generated secret key.</li>
<li>When it is sent: Only once, when a user sets up TOTP-based two-factor authentication. No data is sent during normal login verification.</li>
