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.

OPTIONS

   Login Options
       --registry registry
           Name of the registry to use. Registry names are defined in Cargo config files
           <https://doc.rust-lang.org/cargo/reference/config.html>. If not specified, the default
           registry is used, which is defined by the registry.default config key which defaults
           to crates-io.

   Display Options
       -v, --verbose
           Use verbose output. May be specified twice for "very verbose" output which includes
           extra output such as dependency warnings and build script output. May also be
           specified with the term.verbose config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       -q, --quiet
           Do not print cargo log messages. May also be specified with the term.quiet config
           value <https://doc.rust-lang.org/cargo/reference/config.html>.

       --color when
           Control when colored output is used. Valid values:

           •  auto (default): Automatically detect if color support is available on the terminal.

           •  always: Always display colors.

           •  never: Never display colors.

           May also be specified with the term.color config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   Common Options
       +toolchain
           If Cargo has been installed with rustup, and the first argument to cargo begins with
           +, it will be interpreted as a rustup toolchain name (such as +stable or +nightly).
           See the rustup documentation <https://rust-lang.github.io/rustup/overrides.html> for
           more information about how toolchain overrides work.

       -h, --help
           Prints help information.

       -Z flag
           Unstable (nightly-only) flags to Cargo. Run cargo -Z help for details.

ENVIRONMENT

       See the reference <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
       for details on environment variables that Cargo reads.

EXIT STATUS

       •  0: Cargo succeeded.

       •  101: Cargo failed to complete.
