How to Set Up and Use Multi-Factor Authentication (MFA) for SDL Desktop
A one-time setup, then a quick code at every login. Here is how to enroll your SDL Desktop account in MFA and what to expect each time you sign in afterward.
In this article:
To strengthen the security of your SDL Desktop account, we have enabled multi-factor authentication (MFA) for Parallels access. MFA adds a second layer of verification, so even if your password is ever compromised, your desktop stays protected.
Setup is a one-time process. After that, you will use the new sign-in flow for every future login.

Before You Begin
Before you begin, install an authenticator app on your smartphone. We recommend Google Authenticator or Microsoft Authenticator — both are free on the Apple App Store (iPhone) and the Google Play Store (Android).
| Google Authenticator | Apple App Store | Google Play Store | |
| Microsoft Authenticator | Apple App Store | Google Play Store |
Note: If you don't have a smartphone, you can use a desktop-compatible authenticator instead. Options include:
- The Authenticator browser extension for Chrome
- The Microsoft Edge Authenticator: 2FA Client Add-on
Heads up: if your computer is ever compromised, your browser and its extensions (including a desktop authenticator) may also be compromised. A separate phone or hardware token offers stronger protection.
Part 1: One-Time MFA Setup
The first time you connect after MFA is enabled, Parallels will show a QR code so you can link your authenticator app to your SDL Desktop account. You only do this once per device.
Step 1: Begin the Setup Process
Open the authenticator app on your phone and tap the plus sign (+) in the bottom corner to add a new account.

Step 2: Choose Your Method
Select Scan a QR code. Your phone's camera will activate and a scanning window will appear.

Step 3: Link Your Account
A QR code will be displayed on the Parallels login screen on your computer.

Step 4: Scan with Your Phone
Point your phone's camera at the QR code to scan it. Allow camera access if prompted, then line the QR code up inside the scan window. The app will detect it automatically.

Step 5: Complete the Activation
Once linked, your authenticator app will generate a six-digit code labeled SDL_Hosting (or similar) that refreshes every 30 seconds. Enter this code into the prompt on your computer and click Next to finalize setup.

Alternative: If you cannot scan the QR code, tap Enter a setup key in your authenticator app and manually type the secret key shown beneath the QR code on your computer screen.

Your account is now protected with MFA.
Part 2: Ongoing Login Process
After the one-time setup, your daily login is slightly different. You will use your password plus the six-digit code from your authenticator app every time you connect.
Step 1: Initiate Connection
Open the Parallels client and click Connect as you normally would.

Step 2: Enter Your Username and Password
Sign in with your SDL Desktop credentials as usual.

Step 3: Retrieve Your Authentication Code
Open the authenticator app on your phone. Find the six-digit code associated with your account (look for the entry labeled SDL_Hosting or similar).

Step 4: Enter the Code and Log In
Type the six-digit code into the OTP field in Parallels and click Log In.

Step 5: Access Your Desktop
You are signed in. Your published applications will appear and you can launch your SDL Desktop session.

Heads up: Codes expire every 30 seconds. If your code is close to refreshing when you start typing, wait for the next one so it does not expire before you finish.
Troubleshooting
My six-digit code is not being accepted. Codes change every 30 seconds. Wait for a fresh code in your authenticator app and try again. Also confirm your phone's time is set to automatic, a clock that is off by more than a minute will cause codes to be rejected.
I do not see a QR code on the Parallels screen. Close the Parallels client completely and reopen it, then click Connect again. The QR setup screen only appears on your first MFA login. If you have already set up MFA, you will see the OTP entry dialog instead.
I lost my phone or got a new one. Email support@sdldesktop.com so we can reset your MFA enrollment. Once reset, you will see the QR setup screen the next time you connect.
I cannot scan the QR code. Use the Enter a setup key option in your authenticator app and type in the secret key displayed beneath the QR code on the Parallels screen.
Key Takeaways
- Setup is one-time. After enrolling, you will only need your password and a six-digit code.
- The authenticator app generates a new code every 30 seconds.
- Look for the entry labeled SDL_Hosting in your authenticator app.
- If you lose access to your phone, contact support to reset your enrollment.
