cargo-login(1)
NAME
cargo-login — Log in to a registry
SYNOPSIS
cargo login [options] [-- args]
DESCRIPTION
This command will run a credential provider to save a token so that commands that require authentication, such as cargo-publish(1), will be automatically authenticated.
All the arguments following the two dashes (--) are passed to the credential provider.
For the default cargo:token credential provider, the token is saved
in $CARGO_HOME/credentials.toml. CARGO_HOME defaults to .cargo
in your home directory.
If a registry has a credential-provider specified, it will be used. Otherwise,
the providers from the config value registry.global-credential-providers will
be attempted, starting from the end of the list.
The token 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
--registryregistry- Name of the registry to use. Registry names are defined in Cargo config
files. If not specified, the default registry is used,
which is defined by the
registry.defaultconfig key which defaults tocrates-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.verboseconfig value. -q--quiet- Do not print cargo log messages.
May also be specified with the
term.quietconfig value. --colorwhen- 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.colorconfig value.
Common Options
+toolchain- If Cargo has been installed with rustup, and the first argument to
cargobegins with+, it will be interpreted as a rustup toolchain name (such as+stableor+nightly). See the rustup documentation for more information about how toolchain overrides work. --configKEY=VALUE or PATH- Overrides a Cargo configuration value. The argument should be in TOML syntax of
KEY=VALUE, or provided as a path to an extra configuration file. This flag may be specified multiple times. See the command-line overrides section for more information. -CPATH- Changes the current working directory before executing any specified operations. This affects
things like where cargo looks by default for the project manifest (
Cargo.toml), as well as the directories searched for discovering.cargo/config.toml, for example. This option must appear before the command name, for examplecargo -C path/to/my-project build.This option is only available on the nightly channel and requires the
-Z unstable-optionsflag to enable (see #10098). -h--help- Prints help information.
-Zflag- Unstable (nightly-only) flags to Cargo. Run
cargo -Z helpfor details.
