Getting started

Yoink runs on macOS (Apple Silicon and Intel), Linux (x64 and arm64, glibc and musl/Alpine), and Windows (x64 and arm64). On macOS it stores and swaps credentials through the login Keychain via the securityCLI; on Linux and Windows it works against Claude Code's credentials file. Every install ships a single self-contained binary, so nothing else is needed. On bare Alpine, run apk add libstdc++ libgcc once, the same runtime libraries Node needs there.

Grab Yoink from the download page: the macOS menu bar app, or the CLI one-liner for macOS, Linux, and Windows. The short version on macOS and Linux:

$ curl -fsSL https://yoink.codes/install.sh | bash

Confirm it answers:

$ yoink version

yoink add drives the whole login. It saves your current account first (so it is never lost), then runs claude auth login, which opens the Claude sign-in page. Sign in as the account you want to add and Yoink captures it as a named profile, then offers to add another, so you can register every account in one sitting.

$ yoink add

Open the interactive menu and pick an account, or jump straight to one by name:

$ yoink$ yoink work

Restart Claude Code after switching so it picks up the new credentials. On macOS, the first time Yoink touches the Keychain the system asks for permission: choose Always Allow.
