If you are a PSON student, you must use your Mount Sinai username to sign in and authenticate through the Mount Sinai Sign in page.

There are two separate pages you may encounter during the sign in and authentication process:

  1. Microsoft Account Login Page
  2. Mount Sinai Sign-in Page

Microsoft Account Login Page

If you are redirected to the Microsoft Account login page, enter your provided username + @mountsinai.org


Mount Sinai Sign-in Page

If you are redirected to the Mount Sinai Sign in page, you must enter the appropriate school or hospital prefix + your Mount Sinai username (network ID) 

  • PSON student = MSNYUHEALT\Username
