Security Username and Password 
| ID | SECURITY-6 |
| Title | Do not use hard-coded values for Username and Password. |
| Priority | Mandatory |
| Severity level | 3 |
| Description | Do not use hard-coded values for the properties Username and Password, instead obtain these via a user input action or read them from a (secured) file. |
| Rationale | For security reasons, it is discouraged to use hard-coded username and password since this way they can be easily shared with others accidentally. |
Avoid:
import matlab.net.http.Credentials
creds = Credentials('Username', 'John', 'Password', 'secret');
weboptions("Username", "John", "Password", "secret");
Instead use:
import matlab.net.http.Credentials
% Ask the user to provide a username and password, for example using a dialog or prompt:
[username, password] = showLoginDialog();
creds = Credentials('Username', username, 'Password', password);
weboptions("Username", username, "Password", password);
Note: This is just one example of how to obtain credentials without hardcoding them. Ask your IT department for the available options.
