Use a More Secure OAuth Flow

[MatthewKosloski]

Currently, we are using the Username Password OAuth Flow to connect to Salesforce's REST API.

According to Salesforce,

This method of authentication should only be used in development environments and not for production code. This OAuth authentication flow passes the user’s credentials back and forth. Use this authentication flow only when necessary. No refresh token is issued.

We can potentially use the Device Authentication Flow, which is designed to be used for application with limited input and display capabilities, such as command-line applications.
