cargo-login - Save an API token from the registry locally
cargo login [options] [token]
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.
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.
See the reference <https://doc.rust-lang.org/cargo/reference/environment-variables.html> for details on environment variables that Cargo reads.
