Secure Credentials in MATLAB

Handle API keys, tokens, passwords, and passphrases with the MATLAB Vault, an encrypted store built into MATLAB, instead of hardcoding them. This skill covers the credential — storing it, retrieving it, and passing it into a connection to any authenticated service.

When to Use

• Connecting to any authenticated service or connection from MATLAB — a REST API, database, cloud storage, SFTP/FTP server, message queue, or any other.
• Any code that handles an API key, bearer token, password, or SSH key passphrase.
• Writing CI / batch / scheduled MATLAB that needs credentials with no user present.
• Refactoring credential-handling code, or persisting a config that includes a secret.
• A request to "keep credentials out of code," "don't commit secrets," or "do this the secure way."
