About G Suite Password Sync

G Suite Password Sync (GSPS) automatically keeps your users' G Suite passwords in sync with their Microsoft® Active Directory® passwords. Whenever a user's Active Directory password is changed, GSPS pushes the change to G Suite immediately.

GSPS used to be known as Google Apps Password Sync (GAPS).

Important: GSPS never changes your Active Directory passwords; it only syncs Active Directory password changes to G Suite.

Before you begin

GSPS system requirements

If you have the legacy free edition of Google Apps, upgrade to G Suite to get this feature.

Microsoft Active Directory requirements:
  • Microsoft Active Directory 2008, 2012, or 2016 (AD DS, not AD LDS).  
Set up your domain controllers

  • Domain controllers need an Internet connection to connect to the following sites/ports:


    Purpose URL Port number

    Note: The certificate authority URLs can change at any point. For the most recent list of CRL/OCSP URLs, review the certificate information of the above API and Authentication hosts.
