Simply put, we're making it easier for you to keep everyone protected. Today we are announcing ExchangeDefender MFA support for custom authenticator apps. By now everyone is familiar with our typical MFA functionality, available under your Settings at [https://admin.exchangedefender.com](https://admin.exchangedefender.com/). **Just scan the QR code on your device and you're set!** [![](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2024/02/admin.docker.exchangedefender.com_user-settings.php_-1024x756.png)](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2024/02/admin.docker.exchangedefender.com_user-settings.php_.png) ### BUT WHAT IF YOUR DEVICE DOESN'T HAVE A CAMERA? **ExchangeDefender now supports MFA app enrollment using a QR code.** This is great for scenarios in which: \- You don't have a camera on your device - The QR code doesn't seem to scan (problems with the camera or monitor) - You want to use a text-based MFA app - You want to integrate PowerShell/no-code with MFA - You want to share your MFA codes with others If you're in one of those scenarios, note the text under the QR code when you start the enrollment: [![](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2024/02/admin.docker.exchangedefender.com_user-settings.php-2-717x1024.png)](https://storage.services.exchangedefender.network/exchangedefender-blog/blog/2024/02/admin.docker.exchangedefender.com_user-settings.php-2.png) Click on the **Can't scan? Show code** link and you'll get the TOTP secret (aka secret code, MFA code). Paste it in your solution and paste back the 6 digit code it generates. That's it, you're done. MFA is now enforced and ExchangeDefender will rely on the codes generated by your app to validate MFA and grant access to your account. All our features come from user feedback so if there is something we need to be doing to keep you more secure please let us know!
