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.toml.
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.
