3.4.2 Entering a Password in the Front End

In order to run Mathematica, you must have a mathpass file containing a valid password. This file is created automatically when you enter a password in the front end. The front end presents you with a password dialog box whenever you try to run Mathematica without a valid license. This can happen in any of the following situations.

  • You are starting Mathematica for the first time after installation.

  • The mathpass file has been moved or modified.

  • The license server specified in the mathpass file cannot be found on the network.

  • The license server is on the network, but MathLM is not running.

  • The license server is on the network, but all passwords are already in use.

When you enter a password during the installation process, a mathpass file is automatically created and saved in the $InstallationDirectory/Configuration/Licensing folder. However, if you enter a password in the front end after Mathematica is installed, the mathpass file is saved in the $UserBaseDirectory/Configuration/Licensing folder.

Once the front end password dialog box appears, you have the option of entering a network password or a single-machine password.

To enter a network password via the front end:

1. In a shell, type mathematica. The front end password dialog box appears.

2. Click the radio button marked Network license. Then enter the name or IP address of the license server in the space provided.

3. Click OK. Mathematica launches and is ready for use.

To enter a single-machine password via the front end:

1. In a shell, type mathematica. The front end password dialog box appears.

2. Click the radio button marked Single machine. Then enter your name, the name of your organization, and your license number in the text boxes provided. The license number is printed on the license certificate included in the box. Click OK when you are done.

3. The following dialog box appears showing the MathID number for your machine. You will need to contact Wolfram Research and supply this MathID and your license number to register and obtain a password (see Section 1.4.2 for details).

4. Enter the password in the text box provided, then click OK. Mathematica launches and is ready for use.
