# Moov.js

Use Moov.js to streamline your interactions with the Moov API. With Moov.js, all PII goes straight to Moov so you won't be responsible for storing or handling sensitive user data.

When making calls from the browser, you'll need to specify [scopes](/api/authentication/scopes/) when generating an access token. Scopes specify what actions an account can take. When generating an OAuth2 [access token](/api/authentication/access-tokens/create/), you'll include the name of the scope that covers the type of access needed. You'll use a generated token for each API call you make.
