Authentication and access tokens

Public material pages and library search can be used without an account. Uploading, managing private materials, and account operations require authentication.

For an interactive session, run mtlx login. The CLI stores the resulting credentials locally and mtlx logout removes them. For automation, create a personal access token in your account settings and provide it using the CLI or SDK's token option.

The REST API reference lists each operation's accepted security schemes. Never put a secret token in a browser URL or public repository.
