# cargo-credential-1password A Cargo [credential provider] for [1password]. `cargo-credential-1password` uses the 1password `op` CLI to store the token. You must install the `op` CLI from the [1password website](https://1password.com/downloads/command-line/). You must run `op signin` at least once with the appropriate arguments (such as `op signin my.1password.com user@example.com`), unless you provide the sign-in-address and email arguments. The master password will be required on each request unless the appropriate `OP_SESSION` environment variable is set. It supports the following command-line arguments: * `--account`: The account shorthand name to use. * `--vault`: The vault name to use. * `--sign-in-address`: The sign-in-address, which is a web address such as `my.1password.com`. * `--email`: The email address to sign in with.
