When installing or activating an Individual license, your user name is required. There are multiple ways to obtain your user name:

Command Prompt/Terminal
lmutil Utility
Activation Client

Command Prompt/Terminal

The easiest way to get your user name is from a command prompt or terminal:

Windows

To get your user name via the command prompt:

Locate the search field. On Windows 7 this is in the Start Menu, and on Windows 10, this is in the Taskbar
Enter "cmd" into the search field and type enter
At the command prompt, enter the following command:

>set username
USERNAME=myusername

MacOS

To get your user name, open a Terminal window:

Open Finder.
Open the Applications folder.
Open the Utilities folder.
Start the Terminal application.
In the Terminal window, enter the following command:

%whoami
myusername

Linux

To get your user name, open terminal and run the following command:

%whoami
myusername

lmutil Utility

You can also get your user name by using the lmutil.exe utility. The lmutil utility is included when you install the network license manager using the MathWorks installer or the network license manager binaries.

You can run any of the following commands to determine your user name.

Windows

"C:\Program Files\MATLAB\R20XXx\etc\winXX\lmutil.exe" lmhostid -user

Your user name is displayed as “USER=<your_login_name>”

MacOS

/Applications/MATLAB_R20XXx.app/etc/maci64/lmutil lmhostid -user

Your user name is displayed as “USER=<your_login_name>”

Linux

/usr/local/MATLAB/R2018b/etc/glnxa64/lmutil lmhostid -user

Your user name is displayed as “USER=<your_login_name>”

Activation Client

?If access to any of the other methods is not available, you can use the MATLAB activation client to determine what your user name is.

1. Open the MATLAB activation client. The activation client can be found in the following locations:

Windows

C:\Program Files\MATLAB\R20XXX\bin\win64\activate_matlab.exe.

Mac OS

Use Finder to go to /Applications.
Control-click (right click) on the icon for your MATLAB version, such as MATLAB_R2020a.app .
In the menu, choose Show package contents.
In that directory, start the Activate.app.

Linux

/usr/local/MATLAB/R2018a/bin/activate_matlab.sh

2. When the activation client is open:

Click Activate Manually without the Internet and then click Next.
Click I do not have a license file. Help me with the next steps.
You will then see your user name as "Computer Login Name:<your_user_name>
