Login into the same Netsuite account by different user at the same time.

To give an employee access to NetSuite and assign a password:

1. Go to Lists > Employees > Employees.
2. Click Edit next to the name of the employee for whom you want to set up access.
3. Under Email|Phone|Address, enter the employee’s email address. The email address is required for login.
4. Click the Access tab.
5. Check the Give Access box.
6. Do not check the Send New Access Notification Email box.
7. Check the Manually Assign or Change Password box.
8. Enter a password for the employee. As you type, the characters are validated against the password policy criteria, and the results displayed.
9. In the Confirm Password field, re-enter the password.
10. Check the Require Password Change on Next Login box to require this employee to change their password on their next login to NetSuite.When the employee next logs in, the Change Password page appears. The user cannot access other NetSuite pages until a new password is created and saved. Requiring this action protects your account from unauthorized access using generic passwords and prepares your account for an audit.
11. When you have finished entering information, click Save.
12. Next, tell your user the appropriate login page to go to, the email address to use for login, and the password you assigned. For security reasons, do not send the password by email.

Note: For testing the account should be logged in using different credential through different browser.
