# Sign in to MixShift

Once the plugin is installed, you sign in once and the plugin keeps your session fresh from then on. The whole flow takes about 30 seconds.

## Sign in from a chat

1. Open any chat and say **"sign in to mixshift"** (or just "welcome" if you are brand new).
2. Claude asks for your work email, then opens the MixShift sign-in page in a browser tab.
3. Sign in with your MixShift email and password. Your credentials stay on the sign-in page; the plugin never sees them.
4. Return to the chat and say "done".

Claude confirms the sign-in and shows the brands you have access to.

## Try it

- "What brands do I have access to?"
- "Show me last week's ad spend for [your brand]."
- "Explore my data."

If Claude returns your brands and data, you are set.

## Good to know

- Sign-in uses short-lived tokens that refresh automatically. There are no database passwords to manage and no IP allowlists to set up.
- To switch accounts, just sign in again with the other email.
- Everyone at your MixShift org sees the same brands once signed in. Per-user data scoping is not available today.
- In a terminal, `mixshift auth login` does the same thing for CLI users.

## Signing in from other tools

Cursor, Codex, ChatGPT, and claude.ai connectors reach MixShift through the MCP server rather than the plugin. See [Connect AI tools over MCP](/knowledge-base/builder-platform/how-to/connect-ai-tools-over-mcp).

## Unattended and scheduled work

Anything that runs with nobody at the keyboard (scheduled tasks, automations, CI) uses a service credential instead of a personal sign-in. See [Run unattended and scheduled tasks](/knowledge-base/plugin/how-to/run-unattended-and-scheduled-tasks).
