How to enable or disable two-factor authentication (2FA) in MyKNX

Step-by-step guide to enabling and disabling two-factor authentication for your MyKNX account, and using recovery codes if you lose access to your device.

• 2FA is disabled by default. It's strongly recommended for all accounts and mandatory for accounts using ETS6 cloud licensing.
• Enable it via Account → Profile → Settings using any authenticator app.
• Store your 10 recovery codes safely. You'll need them if you lose access to your authentication device.

Two-Factor Authentication (2FA) adds an extra layer of security to your MyKNX account. Even if your password is compromised, 2FA prevents unauthorized access by requiring a second form of verification.

By default, 2FA is disabled on new MyKNX accounts. Enabling it is strongly recommended for all accounts and mandatory for accounts using ETS6 cloud licensing.

How to enable 2FA

1. Log in to your MyKNX account and go to Account → Profile → Settings.

   
    

2. Click Set Up 2FA.

3. Link your authenticator app by scanning the QR code on screen, or enter the code manually. You can use any authenticator app, for example:

   • Authy (iOS | Android)

   • Google Authenticator (iOS | Android)

   • Microsoft Authenticator (iOS | Android)
     
     
      

4. Once the code is saved in your authenticator app, click Continue.

5. Enter the code generated by your authenticator app and click Activate.
   
   
    
   The confirmation message "Authenticator Activated" appears, and you're provided with 10 recovery codes.
   
   
    
   
   
   Important: Store your recovery codes in a safe place. You'll need them if you ever lose access to your authentication device.

   From now on, you'll be asked for a code from your authenticator app each time you log in to MyKNX.

How to disable 2FA

1. Log in to your MyKNX account and go to Account → Profile → Settings. 

   
    

   2. Click Disable 2FA.

   
   
    

   3. Enter the code generated by your authenticator app and click Disable.
   
   
    

   If the code is correct, 2FA is disabled for your MyKNX account.

How to disable 2FA with a recovery code

If you no longer have access to your authentication device (for example, your mobile phone), you can disable 2FA using one of your recovery codes: 

1. Click Use a recovery code.
2. Enter one of your recovery codes and click Disable.

If the code is correct, 2FA is disabled for your MyKNX account.
