NetSuite continues to strengthen platform security with every release, and the NetSuite 2026.1 update introduces an important change related to simultaneous user sessions. Organizations that previously allowed users to log in from multiple devices at the same time will notice a new default behavior designed to enhance system security and accountability.
If your team relies on concurrent logins for operational workflows, it is important to understand how this update works and how administrators can properly configure it.
In this blog, we will break down the NetSuite 2026.1 multiple sessions update, how to enable the feature, and what administrators should consider before activating it.
What Changed in NetSuite 2026.1?
In NetSuite 2025.2, users were allowed to have multiple simultaneous sessions, meaning the same user account could log in from multiple browsers or devices at the same time (up to three sessions).
Starting with NetSuite 2026.1, this behavior has changed.
Key Change
Multiple sessions are now disabled by default to improve platform security.
Administrators must now manually enable the feature, and it will only work for roles that have Two-Factor Authentication (2FA) enabled.
This ensures that concurrent logins are protected by stronger authentication mechanisms.
Why NetSuite Made This Change
Security remains a major focus for enterprise platforms, especially for ERP systems that manage sensitive financial and operational data.
The new update helps organizations:
Improve account security
Reduce risks associated with shared login credentials
Increase user accountability
Ensure secure authentication practices
By requiring Two-Factor Authentication (2FA) for roles using multiple sessions, NetSuite adds an extra layer of identity verification before allowing concurrent access.
How to Enable Multiple Sessions in NetSuite 2026.1
Administrators who require this functionality can enable it through NetSuite settings.
Follow these steps:
Step 1: Enable the Feature
Navigate to:
Setup → Company → Enable Features
Under the Company subtab and Access section:
Enable “Multiple sessions for 2FA-protected users.”
Click Save.
Step 2: Enable 2FA for User Roles
Navigate to:
Setup → Users/Roles → Two-Factor Authentication Roles
Enable “Two-Factor Authentication Required” for the roles that need multiple session access.
Once this is configured, users assigned to those roles will be able to log in with multiple sessions.
Important Security Warning
While enabling multiple sessions may improve flexibility for certain workflows, NetSuite strongly advises administrators to use this feature carefully.
⚠️ Important Note
This feature should not be used as a workaround to reduce NetSuite license costs by allowing multiple users to share the same account.
Doing so can lead to:
Loss of user accountability
Security vulnerabilities
Audit compliance issues
Data access risks
Each employee should ideally have their own NetSuite user license for proper security and system tracking.
How to Check When Your Account Will Upgrade to NetSuite 2026.1
Not all NetSuite accounts upgrade at the same time. NetSuite schedules updates in phases.
To check your upgrade timeline:
Go to your Home Dashboard
Add the New Release Portlet
The portlet will display your scheduled upgrade date
This allows administrators to prepare for upcoming changes before the system upgrade occurs.
Best Practices for NetSuite Administrators
To prepare for the NetSuite 2026.1 update, administrators should:
Review Login Policies
Evaluate whether your organization truly requires multiple simultaneous sessions.
Enforce 2FA
Ensure that critical roles already have Two-Factor Authentication enabled.
Avoid Shared Accounts
Each employee should have a unique NetSuite login to maintain security and audit compliance.
Test in Sandbox
Before enabling the feature in production, test the configuration in your NetSuite Sandbox environment.
Educate Users
Inform employees about the new login behavior to avoid confusion when the update goes live.
