    6 Reasons for Online Licensing

    Learn why online licensing is the new standard – in 6 compelling points.

    A dark blue checkmark icon symbolizing confirmation or approval against a plain background.

    Simple License Sharing

    Lassen Sie so viele Nutzer mit der Online-Lizenz arbeiten, wie Sie möchten. Die Software kann von jedem Anwender an einem Standort benutzt werden. Die freibleibenden Lizenzen sind weder an einem Computer noch an einem Nutzer gebunden.

    A dark blue checkmark icon symbolizing confirmation or approval against a plain background.

    Fast Sign-In

    Melden Sie sich ganz einfach und bequem über Ihr Dlubal-Konto an, bestehend aus E-Mail-Adresse und Passwort. Das Hin- und Herstecken von USB-Dongles sowie kaputte und verlorene Hardlocks gehören nun der Vergangenheit an.

    A dark blue checkmark icon symbolizing confirmation or approval against a plain background.

    Efficient License Management

    Dank des Lizenzmanagers haben Sie jederzeit den Überblick, welcher Nutzer welche Lizenz bis wann nutzt, und welche Lizenzen zur Verfügung stehen. Ebenfalls können Sie Lizenzen ausleihen, reservieren und im Dlubal-Extranet Autorisierungen verschieben.

    A dark blue checkmark icon symbolizing confirmation or approval against a plain background.

    Access via VPN & Company Network

    Aufgrund der Online-Lizenzierung können Sie nun über VPN oder Ihr eigenes Firmennetzwerk auf die Online-Lizenz zugreifen.

    A dark blue checkmark icon symbolizing confirmation or approval against a plain background.

    Instant License Processing

    Sobald Sie über ein Dlubal-Konto verfügen, können Sie nach der Installation sofort mit dem Programm starten. Ein Einlesen von Autorisierungsdateien gibt es nicht.

    A dark blue checkmark icon symbolizing confirmation or approval against a plain background.

    No server required

    Alle Online-Lizenzen werden auf mehreren Dlubal-Lizenzservern gehostet. Daher benötigen Sie keine eigene Serverinfrastruktur mehr und die Installation von Drivern fällt weg.

    Simple Licensing Management

    Frequently Asked Questions
    How can I get the login credentials?

    If you do not have a Dlubal account yet, you will receive your login data and installation instructions via email. Otherwise, you can create an account in the Dlubal Extranet and download the software. You will only need your email address and a password to log in.

    The installation is performed locally on any number of workstations. Log in with your Dlubal account credentials.

    Note: Preferably use corporate email addresses for better management of users and licenses.

    Learn more Dlubal Online License

    How does the license management work?

    For the online license, you only need a Dlubal account and an internet connection. After logging in, select the license, and you can start working immediately. The connection is only required for the initial login, after which the license remains active for 24 hours.

    The licenses are hosted on Dlubal servers, without separate license management. Communication via port 443 is necessary. If there are problems with the SSL certificate, please check FAQ 5118. FAQ 5118: Login – SSL Handshake Failed

    Note: A license extension is required for multiple locations.

    Is it possible to use a license offline?

    With multiple online licenses, companies benefit from flexible license management. All associated users have access to the purchased licenses, which are not tied to a specific computer or user and can be shared.

    Additionally, a license can be checked out for up to 30 days without a constant internet connection. The loan period can be adjusted directly in the license manager.

    More here FAQ 005307: Borrowing of Online Licenses

    Can I share a license?

    As soon as multiple online licenses are purchased and several users access them, you benefit from flexible license management. In doing so, you benefit from the fact that all users associated with a company with a Dlubal account have access to all purchased licenses. The floating licenses are neither tied to a computer nor a user and can be shared among several users.

    Learn more Dlubal Online License

    Is SSO technology supported for login?

    Single Sign-On (SSO) is an authentication method that allows you to access multiple independent software systems with a single set of login credentials, such as your user name and password.

    RFEM 6, RSTAB 9, and RSECTION 1 provide this login option.
    Using SSO, it is not necessary to log in separately for each system, which simplifies the login process and increases user-friendliness.

    The functionality, advantages, and requirements are explained in FAQ 5658.
