cargo login

NAME

cargo-login - Save an API token from the registry locally

SYNOPSIS

cargo login [OPTIONS] [TOKEN]

DESCRIPTION

This command will save the API token to disk so that commands that require authentication, such as cargo-publish(1), will be automatically authenticated. The token is saved in $CARGO_HOME/credentials. CARGO_HOME defaults to .cargo in your home directory.

If the TOKEN argument is not specified, it will be read from stdin.

The API token for crates.io may be retrieved from https://crates.io/me.

Take care to keep the token secret, it should not be shared with anyone else.
