<h1>Zwei-Faktoren-Authentifizierung</h1>
|
|
|
|
<p>Bislang sind drei Methoden fĂŒr die <em>Zwei-Faktor-Authentifizierung</em> implementiert: WebAuthn (ersetzt seit Februar 2022 U2F), Yubi OTP und TOTP</p>
|
|
<ul>
|
|
<li>Damit WebAuthn funktioniert, benötigen Sie eine verschlĂŒsselte Verbindung zum Server (HTTPS) sowie einen FIDO-SicherheitsschlĂŒssel.</li>
|
|
<li>Sowohl WebAuthn als auch Yubi OTP funktionieren gut mit dem fantastischen <a href="https://www.yubico.com">Yubikey</a>.</li>
|
|
<li>WĂ€hrend Yubi OTP eine aktive Internetverbindung und eine API ID + SchlĂŒssel benötigt, funktioniert WebAuthn mit jedem Fido Security Key, kann aber nur verwendet werden, wenn der Zugriff auf mailcow ĂŒber HTTPS erfolgt.</li>
|
|
<li>WebAuthn und Yubi OTP unterstĂŒtzen mehrere SchlĂŒssel pro Nutzer.</li>
|
|
<li>Als dritte TFA-Methode verwendet mailcow TOTP: zeitbasierte Einmal-Passwörter. Diese Passwörter können mit Apps wie "Google Authenticator" generiert werden, nachdem zunÀchst ein QR-Code gescannt oder das gegebene Geheimnis manuell eingegeben wurde.</li>
|
|
</ul>
|
|
<p>Als Administrator können Sie den TFA-Login eines Domain-Administrators vorĂŒbergehend deaktivieren, bis dieser sich erfolgreich eingeloggt hat.</p>
|
|
<p>Der fĂŒr die Anmeldung verwendete SchlĂŒssel wird in grĂŒner Farbe angezeigt, wĂ€hrend andere SchlĂŒssel grau bleiben.</p>
|
|
<p>Informationen zum Entfernen von 2FA finden Sie <a href="../../../troubleshooting/debug-reset_pw/#zwei-faktor-authentifizierung-entfernen">hier</a>.</p>
|
|
<h2 id="yubi-otp">Yubi OTP<a class="headerlink" href="#yubi-otp" title="Permanent link">¶</a></h2>
|
|
<p>Die Yubi API ID und der SchlĂŒssel werden mit der Yubico Cloud API abgeglichen. Bei der Einrichtung von TFA werden Sie nach Ihrem persönlichen API-Konto fĂŒr diesen SchlĂŒssel gefragt.
|
|
Die API-ID, der API-SchlĂŒssel und die ersten 12 Zeichen (Ihre YubiKeys ID in modhex) werden in der MySQL-Tabelle als Geheimnis gespeichert.</p>
|
|
<h3 id="beispiel-einrichtung">Beispiel-Einrichtung<a class="headerlink" href="#beispiel-einrichtung" title="Permanent link">¶</a></h3>
|
|
<p>Als erstes muss der YubiKey fĂŒr die Verwendung als OTP-Generator konfiguriert werden. Laden Sie dazu den <code>YubiKey Manager</code> von der Yubico Website herunter: <a href="https://www.yubico.com/support/download/">hier</a></p>
|
|
<p>Im Folgenden konfigurieren Sie den YubiKey fĂŒr OTP.
|
|
Ăber den MenĂŒpunkt <code>Anwendungen</code> -> <code>OTP</code> und einem Klick auf den <code>Konfigurieren</code> Button. WĂ€hlen Sie im folgenden MenĂŒ <code>Credential Type</code> -> <code>Yubico OTP</code> und klicken Sie auf <code>Next</code>.</p>
|
|
<p>Setzen Sie ein HĂ€kchen in die Checkbox <code>Use serial</code>, generieren Sie eine <code>Private ID</code> und einen <code>Secret key</code> ĂŒber die SchaltflĂ€chen.
|
|
Damit der YubiKey spÀter validiert werden kann, muss auch das HÀkchen in der <code>Upload</code> Checkbox gesetzt werden und klicken Sie dann auf <code>Finish</code>.</p>
|
|
<p>Nun öffnet sich ein neues Browserfenster, in dem Sie unten im Formular ein OTP Ihres YubiKey eingeben mĂŒssen (auf das Feld klicken und dann auf Ihren YubiKey tippen). BestĂ€tigen Sie das Captcha und laden Sie die Daten auf den Yubico-Server hoch, indem Sie auf 'Hochladen' klicken. Die Verarbeitung der Daten wird einen Moment dauern.</p>
|
|
<p>Nachdem die Generierung erfolgreich war, werden Ihnen eine <code>Client ID</code> und ein <code>Secret key</code> angezeigt, notieren Sie sich diese Informationen an einem sicheren Ort.</p>
|
|
<p>Nun können Sie <code>Yubico OTP-Authentifizierung</code> aus dem Dropdown-MenĂŒ in der mailcow UI auf der Startseite unter <code>Zugang</code> -> <code>Zwei-Faktor-Authentifizierung</code> auswĂ€hlen.
|
|
In dem sich nun öffnenden Dialog können Sie einen Namen fĂŒr diesen YubiKey eingeben und die zuvor notierte <code>Client ID</code> sowie den <code>Secret key</code> in die vorgesehenen Felder eintragen.
|
|
Geben Sie schlieĂlich Ihr aktuelles Kontopasswort ein und berĂŒhren Sie nach Auswahl des Feldes <code>Touch Yubikey</code> die SchaltflĂ€che Ihres YubiKey.</p>
|
|
<p>Herzlichen GlĂŒckwunsch! Sie können sich nun mit Ihrem YubiKey in die mailcow UI einloggen!</p>

<p><strong>Seit Februar 2022 hat Google Chrome die UnterstĂŒtzung fĂŒr U2F aufgegeben und die Verwendung von WebAuthn standardisiert.<br></strong>
|
|
<em>Die WebAuthn API (der Ersatz fĂŒr U2F) ist seit dem 21. Januar 2022 Teil von mailcow, wenn Sie also den Key ĂŒber Februar 2022 hinaus nutzen wollen, sollten Sie ein Update mit der <code>update.sh</code></em> in Betracht ziehen. </p>
|
|
</div>
|
|
<p>Um WebAuthn zu nutzen, muss der Browser diesen Standard unterstĂŒtzen:</p>
|
|
<ul>
|
|
<li>Edge (>=18)</li>
|
|
<li>Firefox (>=60)</li>
|
|
<li>Chrome (>=67)</li>
|
|
<li>Safari (>=13)</li>
|
|
<li>Opera (>=54)</li>
|
|
</ul>
|
|
<p>Die folgenden mobilen Browser unterstĂŒtzen diesen Authentifizierungstyp:</p>
|
|
<ul>
|
|
<li>Safari auf iOS (>=14.5)</li>
|

|
<p>Mit dem neuen U2F-Ersatz (WebAuthn) mĂŒssen Sie Ihren Fido Security Key neu registrieren, zum GlĂŒck ist WebAuthn abwĂ€rtskompatibel und unterstĂŒtzt das U2F-Protokoll.</p>
|
|
</div>
|
|
<p>Im Idealfall sollten Sie beim nĂ€chsten Einloggen (mit dem SchlĂŒssel) ein Textfeld erhalten, das besagt, dass Ihr Fido Security Key aufgrund des Updates auf WebAuthn entfernt und als 2-Faktor-Authentifikator gelöscht wurde.</p>
|
|
<p>Aber keine Sorge! Sie können Ihren bestehenden SchlĂŒssel einfach neu registrieren und ihn wie gewohnt verwenden. Sie werden wahrscheinlich nicht einmal einen Unterschied bemerken, auĂer dass Ihr Browser die U2F-Deaktivierungsmeldung nicht mehr anzeigt.</p>
|
|
<h3 id="deaktivieren-inoffizieller-unterstutzter-fido-security-keys">Deaktivieren inoffizieller unterstĂŒtzter Fido Security Keys<a class="headerlink" href="#deaktivieren-inoffizieller-unterstutzter-fido-security-keys" title="Permanent link">¶</a></h3>
|
|
<p>Mit WebAuthn gibt es die Möglichkeit, nur offizielle Fido Security Keys zu verwenden (von den groĂen Marken wie: Yubico, Apple, Nitro, Google, Huawei, Microsoft, usw.) zu verwenden.</p>
|
|
<p>Dies dient in erster Linie der Sicherheit, da es Administratoren ermöglicht, sicherzustellen, dass nur offizielle Hardware in ihrer Umgebung verwendet werden kann.</p>
|
|
<p>Um diese Funktion zu aktivieren, Àndern Sie den Wert <code>WEBAUTHN_ONLY_TRUSTED_VENDORS</code> in mailcow.conf von <code>n</code> auf <code>y</code> und starten Sie die betroffenen Container mit <code>docker compose up -d</code> neu.</p>
|
|
<p>Die mailcow wird nun die Vendor-Zertifikate verwenden, die sich in Ihrem mailcow-Verzeichnis unter <code>data/web/inc/lib/WebAuthn/rootCertificates</code> befinden. </p>
|
|
<h5 id="beispiel">Beispiel:<a class="headerlink" href="#beispiel" title="Permanent link">¶</a></h5>
|
|
<p>Wenn Sie die offiziellen Hersteller-GerÀte nur auf Apple beschrÀnken wollen, brauchen Sie nur das Apple Hersteller-Zertifikat im <code>data/web/inc/lib/WebAuthn/rootCertificates</code>.
|
|
Nachdem Sie alle anderen Zertifikate gelöscht haben, können Sie WebAuthn 2FA nur noch mit Apple-GerÀten aktivieren.</p>
|
|
<p>Das ist fĂŒr jeden Hersteller gleich, also wĂ€hlen Sie aus, was Ihnen gefĂ€llt (wenn Sie es wollen).</p>
|
|
<h4 id="eigene-zertifikate-fur-webauthn-verwenden">Eigene Zertifikate fĂŒr WebAuthn verwenden<a class="headerlink" href="#eigene-zertifikate-fur-webauthn-verwenden" title="Permanent link">¶</a></h4>
|
|
<p>Wenn du ein gĂŒltiges Zertifikat vom Hersteller deines SchlĂŒssels hast, kannst du es auch zu deiner Mailcow hinzufĂŒgen!</p>
|
|
<p>Kopieren Sie einfach das Zertifikat in den <code>data/web/inc/lib/WebAuthn/rootCertificates</code> Ordner und starten Sie Ihre Mailcow neu.</p>
|
|
<p>Nun sollten Sie in der Lage sein, auch dieses GerĂ€t zu registrieren, obwohl die ĂberprĂŒfung fĂŒr die Herstellerzertifikate aktiviert ist, da Sie das Zertifikat manuell hinzugefĂŒgt haben. </p>
|
|
<h4 id="ist-es-gefahrlich-den-vendor-check-deaktiviert-zu-lassen">Ist es gefĂ€hrlich, den Vendor Check deaktiviert zu lassen?<a class="headerlink" href="#ist-es-gefahrlich-den-vendor-check-deaktiviert-zu-lassen" title="Permanent link">¶</a></h4>
|
|
<p>Nein, das ist es nicht!
|
|
Diese Herstellerzertifikate werden nur zur ĂberprĂŒfung der Originalhardware verwendet, nicht zur Absicherung des Registrierungsprozesses.</p>
|
|
<p>Wie Sie in diesen Artikeln lesen können, hat die Deaktivierung nichts mit der Software-Sicherheit zu tun:

|
|
<p>Letztendlich ist es aber natĂŒrlich Ihre Entscheidung, ob Sie dieses HĂ€kchen deaktiviert oder aktiviert lassen. </p>
|

|
<h2 id="totp">TOTP<a class="headerlink" href="#totp" title="Permanent link">¶</a></h2>
|
|
<p>Die bekannteste TFA-Methode, die meist mit einem Smartphone verwendet wird.</p>
|
|
<p>Um die TOTP-Methode einzurichten, loggen Sie sich in die Admin UI ein und wÀhlen Sie <code>Time-based OTP (TOTP)</code> aus der Liste.</p>
|
|
<p>Nun öffnet sich ein Modal, in dem Sie einen Namen fĂŒr Ihr 2FA-"GerĂ€t" (Beispiel: John Deer's Smartphone) und das Passwort des betroffenen Admin-Kontos (mit dem Sie derzeit eingeloggt sind) eingeben mĂŒssen.</p>
|
|
<p>Sie haben zwei verschiedene Methoden, um TOTP fĂŒr Ihr Konto zu registrieren:
|
|
1. Scannen Sie den QR-Code mit Ihrer Authenticator App auf einem Smartphone oder Tablet.
|
|
2. Verwenden Sie den TOTP-Code (unter dem QR-Code) in Ihrem TOTP-Programm oder Ihrer App (wenn Sie keinen QR-Code scannen können).</p>
|
|
<p>Nachdem Sie den QR- oder TOTP-Code in der TOTP-App/dem TOTP-Programm Ihrer Wahl registriert haben, mĂŒssen Sie nur noch den nun generierten TOTP-Token (in der App/dem Programm) als BestĂ€tigung in der mailcow UI eingeben, um die TOTP 2FA endgĂŒltig zu aktivieren, ansonsten wird sie nicht aktiviert, obwohl der TOTP-Token bereits in Ihrer App/ Ihrem Programm generiert wurde.</p>
