# Sign Out

> Sign out the current user and invalidate the refresh token family

Signs out a user by invalidating their refresh token and the entire token family associated with it. All rotated tokens from the same session are revoked, preventing future token refreshes.

The endpoint always returns `204 No Content`, even if the refresh token is missing, invalid, or already expired. This ensures sign-out is always safe to call.

## Body Parameters

<ParamField body="refreshToken" type="string">
  The refresh token JWT to invalidate. If omitted or `null`, the server returns
  `204` without performing any revocation.
</ParamField>

## Response

Returns `204 No Content` on success. No response body.
