CARGO-LOGOUT(1) General Commands Manual CARGO-LOGOUT(1)

cargo-logout — Remove an API token from the registry locally

cargo logout [options]

This command will run a credential provider to remove a saved token.

For the default cargo:token credential provider, credentials are stored in $CARGO_HOME/credentials.toml where $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.

If --registry is not specified, then the credentials for the default registry will be removed (configured by registry.default https://doc.rust-lang.org/cargo/reference/config.html#registrydefault, which defaults to https://crates.io/).

This will not revoke the token on the server. If you need to revoke the token, visit the registry website and follow its instructions (see https://crates.io/me to revoke the token for https://crates.io/).

--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.

-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.

+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.

--config KEY=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 https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides for more information.

-C PATH

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 example cargo -C path/to/my-project build.

This option is only available on the nightly channel https://doc.rust-lang.org/book/appendix-07-nightly-rust.html and requires the -Z unstable-options flag to enable (see #10098 https://github.com/rust-lang/cargo/issues/10098).

-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.
