--token TOKEN

API token to use when authenticating. This overrides the token stored in the credentials file (which is created by man:cargo-login[1]).

linkcargo:reference/config.html[Cargo config] environment variables can be used to override the tokens stored in the credentials file. The token for crates.io may be specified with the CARGO_REGISTRY_TOKEN environment variable. Tokens for other registries may be specified with environment variables of the form CARGO_REGISTRIES_NAME_TOKEN where NAME is the name of the registry in all capital letters.
