## Beskriuwing

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:**

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

## Ynstallaasje

 1. Upload the `oosoft-2fa-security` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the **Plugins** menu in WordPress.
 3. Go to **Settings > 2FA Security** to configure enforcement rules and options.
 4. Users can set up their preferred 2FA method from their **Profile** page.

## FAQ

### Which authenticator apps are supported?

Any app that supports the TOTP standard (RFC 6238), including Google Authenticator,
Authy, Microsoft Authenticator, and 1Password.

### What happens if a user loses their authenticator app?

Users can log in with one of their backup codes. Administrators can also disable
2FA for a user from the Users list.

### Is TOTP secret storage secure?

Yes. Secrets are encrypted with AES-256 (libsodium secretbox preferred, OpenSSL 
AES-256-GCM/CBC as fallback) before being stored in the database. Encryption keys
are derived from your site’s unique WordPress secret keys via HKDF-SHA256.

### Does this plugin work with WooCommerce or custom login forms?

The plugin intercepts WordPress’s core authentication pipeline, so it works with
any theme or plugin that uses `wp_signon()` or the standard login form.
