How to Enforce Strict Session Lengths (Timeouts) in Google Workspace

The Risk of Persistent Sessions

When an employee logs into their Google Workspace account, Google drops a secure authentication cookie into their browser. By default, this session cookie is valid for 14 days. This means the employee does not need to enter their password or fulfill a 2-Step Verification (2SV) prompt every time they open their laptop; they are simply kept logged in.

While this is incredibly convenient, it presents a massive security risk in certain environments. If a hospital nurse logs into Google Drive on a shared terminal in a patient room, or if a contractor logs in from a public library computer and forgets to click “Sign Out,” that 14-day persistent session is a ticking time bomb. Anyone who sits down at that computer can access the corporate data.

To mitigate this risk, system administrators must strictly enforce Google Session Lengths (Timeouts).

Accessing the Session Settings

You configure session controls within the core security panel of the Admin Console.

1. Log into the Google Workspace Admin Console using Super Administrator credentials.
2. Navigate to Security > Access and data control > Google session control.

Applying Targeted Policies

You should almost never apply a strict 1-hour timeout to the entire organization, as the executive team will mutiny having to re-authenticate via their smartphones 8 times a day.

Instead, use Organizational Units (OUs).

1. On the left-hand panel, select the specific OU that requires high security (e.g., Shared Kiosks, Contractors, or Finance Dept).
2. In the main window, you will see the primary setting: Google session length.

Configuring the Timeout Duration

You have granular control over exactly when the session cookie is forcibly expired.

1. Change the setting from “14 days” to a more restrictive window, such as 8 Hours (the length of a standard shift) or even 1 Hour for highly sensitive terminals.
2. Warning before logout: Google provides a helpful feature where, 5 minutes before the session is destroyed, the user receives a popup warning them that their session is expiring. (Note: It is highly recommended to leave this enabled so users do not lose unsaved work in Google Docs).
3. Click Save.

The Administrative Exception

Google enforces a separate, non-negotiable policy for users who hold the Super Administrator role. Regardless of how you configure the general session length, a Super Administrator session is hard-capped at 1 hour when accessing the Google Admin Console interface.

If an admin logs in to change a setting and then leaves their desk, the session is aggressively destroyed 60 minutes later, requiring a fresh password and 2SV token to regain access to the domain controls. This is a hard-coded security mechanism by Google to prevent rogue access to the root account.
