# Account and security

Open **Account** to change your profile and photo, review connected sign-in accounts, revoke active sessions, and inspect MCP connections. Atmina supports passwordless email sign-in and the social providers shown on the sign-in page.

The **Security** section lets you protect the account with an authenticator app. Enable two-factor authentication, scan the QR code (or enter the setup key), then confirm with a 6-digit code from the app.

Removing a connected account or session can sign a client out. Revoke an MCP connection when the client is lost or should no longer act with your access; reconnect it from the Knowledge Base when needed.

The Account page also shows your Teams, linked Channel accounts, recent activity, export controls, and account deletion. Export first if you need a copy. Account deletion may be blocked while you remain the owner of a shared Team; transfer or erase that Team before retrying.

See [MCP authentication](https://atmina.ai/docs/mcp-authentication) for agent connection details.
