Unlocking the Benefits of Azure Passwordless with FIDO2 Keys


We understand that some of our customers have questions and concerns about migrating to Azure Passwordless with FIDO2 keys. With this blog post, we aim to address and clarify some of the common queries that may arise regarding the technology.

Our goal is to help our customers make informed decisions about their authentication processes and realize the benefits of Azure Passwordless without any confusion or uncertainty.

Azure Passwordless with FIDO2 Security keys offers a robust authentication technology that allows users to log in to their accounts without using traditional passwords. FIDO2 Security keys use public-key cryptography to provide strong authentication and are protected with PIN and biometric verification. This is one of the few phishing resistant authentication methods available for Azure, and despite some myths, is one of the most secure ones.


Azure Passwordless does not require any extra license to use it. It works with the cheapest plan, making it an affordable and accessible authentication solution for organizations of any size. Once enrolled, access to services works out of the box without any additional licenses required.

Mobile platform support

One of the primary drawbacks of using Azure Passwordless with FIDO2 Security keys is the lack of mobile platform support by Microsoft's implementation. However, this problem can be resolved by using Microsoft Authenticator as an additional authentication method. Microsoft Authenticator is a mobile app that provides two-factor authentication and passwordless sign-in to Microsoft accounts. It supports FIDO2 Security keys, so users can use their keys with the Authenticator app to sign in to Azure accounts on their mobile devices.

Configuring workstation login with FIDO2 keys

Once enrolled, users can use their FIDO2 keys to securely log in to their Windows 10/11 workstations. This may not enabled by default in the operating system settings, but it takes literally a couple of clicks for the IT support staff to enable this feature. This can be done using simple registry modification or via Intune method (requires Intune license).

Despite some minor limitations, Azure Passwordless with FIDO2 Security keys still offers significant benefits. For instance, FIDO2 Security keys provide a higher level of security compared to traditional passwords. With FIDO2 Security keys, users do not have to worry about passwords being compromised or stolen, as the keys use strong encryption to protect their data. Additionally, Azure Passwordless with FIDO2 Security keys can offer more convenience for users. They do not have to remember complex passwords or worry about resetting them every few months. Instead, they can use their FIDO2 Security keys to authenticate themselves easily and quickly. In summary, Azure Passwordless with FIDO2 Security keys is a powerful authentication technology that provides a high level of security and convenience to users. Although the lack of mobile platform support by Microsoft's implementation of FIDO2 Security keys may be a minor drawback, the benefits of this technology make it a worthwhile investment for any organization looking to improve their authentication process.

If you're looking for a secure and hassle-free way to authenticate your users, Azure Passwordless with FIDO2 Security keys is the way to go. It's a proven technology that's ready for production and will enhance the security of your organization's sensitive data.
