The quick answer
On your Home dashboard, find the Settings portlet and click Active Sessions. The page tells you how many NetSuite UI sessions your user has open, for example "You have 3 active sessions." It doesn't say which browsers or devices they're on. Click Invalidate other sessions to end every session except the one you're using. The page then reads "You have 1 active session." and the button goes grey. The other browsers can't keep using their sessions. They're asked to sign in again when they next contact NetSuite.

Before you start
You only get more than one session when your account allows it. An administrator turns on Multiple Sessions for 2FA-protected Users under Setup > Company, and every role assigned to your user has to require two-factor authentication. Then you can have up to three NetSuite UI sessions open at once. If any one of your roles doesn't require 2FA, you're limited to one. From 2026.1 the setting stays off until an administrator turns it on. Accounts upgraded from earlier releases may differ, so check yours before you rely on it.
Tabs in the same browser share one session, so opening more tabs doesn't add sessions. A different browser or a different device can each have its own.
In the example, a controller signed in this week on an office desktop, a laptop at a supplier visit and a shared tablet in the shipping office, and wants only the desktop signed in before the weekend. Everything below happens on the desktop. The laptop and the tablet aren't in the screenshots.
If you can, save open records on the other devices first. Unsaved changes there may be lost, because an ended session can't submit them.
01. Open Active Sessions and read the count
Go to your Home dashboard and find the Settings portlet. It holds links like Set Preferences, Change Password and Manage Access Tokens, though the exact list depends on your role and account. Click Active Sessions.
The portlet can sit anywhere on a customized dashboard. If you can't find it, your dashboard may have been personalized or published without it. Add it back, or ask your administrator.
The Active Sessions page has one button, Invalidate other sessions, and one sentence. Here it's "You have 3 active sessions." That's this desktop plus two others. The page doesn't identify them by browser or device, so you can't pick one session to end. The only choice is to end all the others.
02. Invalidate the other sessions
Click Invalidate other sessions. Here it acts straight away, with no confirmation prompt, so be sure before you click. The session you clicked from stays signed in.
The page now reads "You have 1 active session." and Invalidate other sessions is greyed out. With only your current session left, there's nothing else to end. You'll see the button greyed out any time you have just one session.
03. Confirm the result from Home
Click the Home icon, then click Active Sessions in the Settings portlet again. The page still reads "You have 1 active session." with the button greyed out, and you're still working in the same session. That confirms the count from your side.
Check the result (example values)
- Before the click, Active Sessions read "You have 3 active sessions." with the button available.
- After the click, it reads "You have 1 active session." and Invalidate other sessions is greyed out.
- Reopened from the Home dashboard, it still reads "You have 1 active session."
- You stayed signed in on the browser you clicked from.
The other browsers don't change on screen right away. The laptop and the tablet keep showing whatever page they were on until they next contact NetSuite. When someone clicks or refreshes there, the ended session can't continue and NetSuite asks them to sign in again.
If you think someone else used your login, ending the other sessions is only the first step. Follow your company's security procedure, which usually means changing your password too. Active Sessions covers your own NetSuite UI sessions. It doesn't revoke access tokens or OAuth authorizations for integrations. Those are managed separately, and in this account the Settings portlet links to both.
Common questions
Why is Invalidate other sessions greyed out?
You have only one active session, the one you're using, so there's nothing else to end. The button comes back once you're signed in somewhere else too, as long as your account allows more than one session.
Can I sign out just one device or browser?
No. The page shows a count, not which devices or browsers the sessions are on. Invalidate other sessions ends all of them except yours in one go.
Does it sign me out of the browser I'm using?
No. The session you click it from stays signed in. The other browsers are asked to sign in again the next time they contact NetSuite.
Why can I only have one session when multiple sessions are turned on?
Check your roles. Multiple Sessions for 2FA-protected Users only applies when every role assigned to you requires two-factor authentication. If even one doesn't, NetSuite keeps you to one UI session. When you do qualify, the limit is three.
Can an administrator end another user's sessions from this page?
No. Active Sessions only covers the sessions of the user who's signed in. It isn't an admin tool for signing out other employees.
Does it revoke integration tokens or OAuth authorizations?
No. It only ends NetSuite UI sessions. Access tokens and OAuth authorizations used by integrations keep working until you revoke them separately.
