Store Credentials for Data Service Connections

When connecting to a data server that requires your username and password, you can gain access by including them in your code. However, this mode of connection exposes your credentials to a security risk. Instead, protect your credentials by storing them in the MATLAB^® vault, which provides a secure way to store sensitive information, such as passwords, API keys, tokens, and credentials.

To store your username and password, create your secret prompt by using the setSecret function for each of these secrets.

setSecret("username");
setSecret("password");

When the dialog box appears for each secret, enter your credentials and click OK.

Before you connect, retrieve your credentials by using the getSecret function.

username = getSecret("username");
password = getSecret("password");

Finally, create the connection using your stored credentials. For example, connect to the Intercontinental Exchange^® (ICE^®) data server by creating an ice connection object.

conn = ice(username,password)

conn = 

  ice with properties:

    TimeOut: 200
   UserName: "username"

Creating the ice connection object by retrieving your username and password from the MATLAB vault, keeps your user credentials secret.
