3DEXPERIENCE Two Factor Authentication 2FA
As part of their commitment to enhance the security of your account and protect your data, starting July 8, 2025, Dassault Systèmes now requires users to apply Two-Factor Authentication (2FA) for 3DS applications and DSx.Client Care & Order. 2FA is a standard that adds an extra layer of security by requiring a second verification step when signing into your account.
This document is a guideline on how to activate your 2FA using a mobile app like Google Authenticator or using a computer app.
Section 1 details setting up the 2FA on a mobile device (recommended and most common)
Section 2 details setting up a computer authenticator instead of a mobile device.
Section 1: Setting up 2FA on a Mobile Device
- Download and install a Mobile Authenticator. This example uses Google Authenticator. Other tools such as Microsoft Authenticator, Okta, and other mobile authenticators can also be used. See Section 2 for an alternative method which does not require a mobile device.
- Log into https://eu1.iam.3dexperience.3ds.com/ using your username and password.
- In the top left corner of the My 3DEXPERIENCE ID dialog, click the My Profile button to display a dropdown menu. Select 2-Factor Authentication to begin setting up authentication.
- Click the Activate button to begin.
- Set Recovery Options and then click Save to continue.
- Scan the QR code generated by the system or enter the 2FA backup key into your 2-Factor Authenticator on your mobile device.
Once registered on your mobile device, enter the code displayed on your mobile device into ‘Current code displayed by your application’ and click Validate.
Once validated, a confirmation screen will display. Click Back to return to the 3DS site and log in.
- Deactivate to stop 2FA. Note, you will need to activate again to access 3DS sites.
- Transfer to move your authentication to a new mobile device.
- Back to switch back to your 3DS site and log in.
- Test authentication by logging into your 3DS account. Each time you log out, you will need to access the authentication app on your mobile device and enter the code to log back in.
Section 2: Setting up a Computer Authenticator
This section details how to activate 2-Factor Authentication on a computer as an alternative to a mobile device. Dassault Systèmes recommends the use of KeePasXC, which is an open-source password manager that can be used on Windows, macOS, and Linux. Other Time-Based One-Time Password applications can also be used.
This example uses KeePassXC as the authenticator application.
- Download and install KeePassXC (open source passwords manager) The default install options are sufficient for the purposes of this guide. Consult your IT professional for information pertaining to the install and management of KeePassXC or other authentication applications.
- Click Create Database to create a new storage location for passwords and tokens. You can keep the default settings or adjust to meet your needs. Part of the Create Database process is to create a password to access the new database. Be sure to keep the password stored in a secure location for future use.
- Click the + icon to add a new entry. Fill in the Title (a descriptive title), Username and Password used to log into your 3DEXPERIENCE ID, and URL https://dsxclient.3ds.com/
- Right-click the new entry and select TOTP > Set up TOTP
- In the Setup TOTP dialog, copy the ‘2FA Backup Key’ from the Dassault Systèmes 2-Factor Authentication Activation (step 1-6 of section 1 in this guide). This will display the key needed to connect your computer authenticator as described in the next steps.
Paste the 2FA Backup Key into the Secret Key field of KeePassXC and then click OK.
- Now that the key is configured, it’s time to test it out. This step is time sensitive. Double-click the clock icon next to the key entry to generate the authentication code. The code will be copied to your clipboard automatically—you will not see the code—and then you’ll have 10-seconds to paste the code either into the Dassault Systèmes 2-Factor Authentication. Watch the timer on the lower right of KeePassXC.
Before the clipboard is cleared, paste the code into the Dassault Systèmes window ‘Current code displayed by your application’ and click Validate.
Once validated, a confirmation screen will display. Click Back to return to the 3DS site and log in.
- Deactivate to stop 2FA. Note, you will need to activate again to access 3DS sites.
- Transfer to move your authentication to a new computer.
- Back to switch back to your 3DS site and log in.
- Test authentication by logging into your 3DS account. Each time you log out, you will need to access the authentication app on your computer and enter the code to log back in.
