When signing in, I get "Error! can't support multiple login in the single account"

This error means one of the following:

• Your account is already signed in on another device or in another browser window.
• You signed in using a browser that does not accept 3rd-party cookies. You then closed the browser window without signing out, so your account is still signed in.
  

To prevent this error:

• Ensure users do not share accounts.
• Ensure that your browser allows 3rd-party cookies.
• Do not use the NeuroPilot portal in a Private or Incognito browser window, as your browser will discard cookies when the window is closed.
