Certificate (RFC 7523 client assertion) as an alternative to the client secret: one-click generation of a 3072-bit RSA key pair with a self-signed certificate, .cer download (public part only), own PEM upload with validation, expiry display, encrypted key storage. Both the authorization code exchange and the Graph client-credentials request use the selected method. Step-by-step guides for secret, certificate and the app registration are shown in the settings. Security audit (docs/security-audit.md) and fixes: - Multi-tenant mode ignored the unverified email claim: matching now uses the UPN only, or the email claim when xms_edov is true. - Login starts are rate limited per client (30 per 10 minutes). - Optional trusted proxy header for client IPs (M365_LOGIN_CLIENT_IP_HEADER / filter).

## [1.0.0] – 2026-09-22
|
||
|
||
### Added
|
||
- "Sign in with Microsoft" button on `wp-login.php` (OpenID Connect authorization code flow with PKCE).
|
||
- Matching of existing WordPress users by e-mail address (optional UPN fallback), no user provisioning.
|
||
- Settings screen (Settings → M365 Login) with connection, button and security tabs, live button preview, colour presets, media-library icon picker, redirect-URI copy button and tenant connectivity test.
|
||
- ID token verification against Microsoft's JWKS (RS256, issuer, audience, tenant, expiry, nonce).
|
||
- Encrypted client secret storage (AES-256-GCM).
|
||
- Certificate based client authentication (RFC 7523 `private_key_jwt`): one-click generation of a 3072-bit RSA key pair with self-signed certificate, `.cer` download, own PEM upload, expiry display; step-by-step guides for both methods in the settings.
|
||
- Security audit (docs/security-audit.md) with fixes: unverified `email` claim ignored in multi-tenant mode, login-start rate limit, trusted proxy IP header.
|
||
- Account binding to the Microsoft object ID, e-mail domain allow-list.
|
||
- Entra group restriction with a Graph-powered group picker; membership verified via the `groups` claim or Microsoft Graph `checkMemberGroups`.
|
||
- Button-only mode that hides the password form and blocks password sign-in on `wp-login.php`, with a secret, rate-limited fallback link and a `wp-config.php` emergency constant.
|
||
- Custom login page support: automatic button in `wp_login_form()` forms, `m365_login_button()` / `m365_login_messages()` template functions, custom login URL for error messages, fallback link and logout redirect.
|
||
- `[m365_login_button]` shortcode (with `divider` and `messages` attributes) and developer hooks.
|
||
- German translation.
