A password manager, digital vault, form filler and secure digital wallet. 1Password remembers all your passwords for you to help keep account information safe. The Account Key is generated on a single device (at account setup) and never transmitted. The Account Key is random, so it's actually making our weak (relatively speaking) Master Passwords (which we need to be able to memorize and type) stronger. The Account Key is used (along with the Master Password) to encrypt the data. Apr 17, 2018 FIDO2 compliant security keys provide secure authentication, independent of the form factor. The security key holds your credential and can be protected with an additional second factor like fingerprint (integrated into the security key) or a PIN to be entered at the Windows sign-in. Our partners are working on a variety of security key form factors. It's simply a resource that can be used by Azure Active Directory to generate Kerberos TGTs for your Active Directory Domain. User signs in to their Windows 10 device with a FIDO2 security key and authenticates to Azure AD. Azure AD checks the directory for a Kerberos server key matching the user's on-premises AD domain. Thanks for the feedback! Currently, we don't offer native U2F/Yubikey support because the combined security punch of the Master Password and Secret Key's encryption makes the added authentication step of 2FA (whether code-based or hardware key based) significantly less important to keeping your 1Password account secure.
-->This document focuses on enabling passwordless authentication to on-premises resources for environments with both Azure AD joined and hybrid Azure AD joined Windows 10 devices. This functionality provides seamless single sign-on (SSO) to on-premises resources using Microsoft-compatible security keys.
FIDO2 security keys are a public preview feature of Azure Active Directory. For more information about previews, see Supplemental Terms of Use for Microsoft Azure Previews |
SSO to on-premises resources using FIDO2 keys
Azure Active Directory (AD) can issue Kerberos Ticket Granting Tickets (TGTs) for one or more of your Active Directory domains. This functionality allows users to sign into Windows with modern credentials like FIDO2 security keys and access traditional Active Directory based resources. Kerberos Service Tickets and authorization continue to be controlled by your on-premises Active Directory domain controllers.
An Azure AD Kerberos Server object is created in your on-premises Active Directory and then securely published to Azure Active Directory. The object isn't associated with any physical servers. It's simply a resource that can be used by Azure Active Directory to generate Kerberos TGTs for your Active Directory Domain.
- User signs in to their Windows 10 device with a FIDO2 security key and authenticates to Azure AD.
- Azure AD checks the directory for a Kerberos server key matching the user's on-premises AD domain.
- Azure AD generates a Kerberos TGT for the user's on-premises AD domain. The TGT only includes the user's SID. No authorization data is included in the TGT.
- The TGT is returned to the client along with their Azure AD Primary Refresh Token (PRT).
- The client machine contacts an on-premises AD domain controller and trades the partial TGT for a fully formed TGT.
- The client machine now has an Azure AD PRT and a full Active Directory TGT and can access both cloud and on-premises resources.

Note
Replace
contoso.corp.com
in the following example with your on-premises Active Directory domain name.Viewing and verifying the Azure AD Kerberos Server
You can view and verify the newly created Azure AD Kerberos Server using the following command:
This command outputs the properties of the Azure AD Kerberos Server. You can review the properties to verify that everything is in good order.
Property | Description |
---|---|
ID | The unique ID of the AD DS DC object. This ID is sometimes referred to as it's 'slot' or it's 'branch ID'. |
DomainDnsName | The DNS domain name of the Active Directory Domain. |
ComputerAccount | The computer account object of the Azure AD Kerberos Server object (the DC). |
UserAccount | The disabled user account object that holds the Azure AD Kerberos Server TGT encryption key. The DN of this account is CN=krbtgt_AzureAD,CN=Users,<Domain-DN> |
KeyVersion | The key version of the Azure AD Kerberos Server TGT encryption key. The version is assigned when the key is created. The version is then incremented every time the key is rotated. The increments are based on replication meta-data and likely greater than one. For example, the initial KeyVersion could be 192272. The first time the key is rotated, the version could advance to 212621. The important thing to verify is that the KeyVersion for the on-premises object and the CloudKeyVersion for the cloud object are the same. |
KeyUpdatedOn | The date and time that the Azure AD Kerberos Server TGT encryption key was updated or created. |
KeyUpdatedFrom | The DC where the Azure AD Kerberos Server TGT encryption key was last updated. |
CloudId | The ID from the Azure AD Object. Must match the ID above. |
CloudDomainDnsName | The DomainDnsName from the Azure AD Object. Must match the DomainDnsName above. |
CloudKeyVersion | The KeyVersion from the Azure AD Object. Must match the KeyVersion above. |
CloudKeyUpdatedOn | The KeyUpdatedOn from the Azure AD Object. Must match the KeyUpdatedOn above. |
Rotating the Azure AD Kerberos Server key
The Azure AD Kerberos Server encryption krbtgt keys should be rotated on a regular basis. It's recommended that you follow the same schedule you use to rotate all other Active Directory Domain Controller krbtgt keys.
Warning
There are other tools that could rotate the krbtgt keys, however, you must use the tools mentioned in this document to rotate the krbtgt keys of your Azure AD Kerberos Server. This ensures the keys are updated in both on-premises AD and Azure AD.
Removing the Azure AD Kerberos Server
If you'd like to revert the scenario and remove the Azure AD Kerberos Server from both on-premises Active Directory and Azure Active Directory, run the following command:
Multi-forest and multi-domain scenarios
The Azure AD Kerberos server object is represented in Azure AD as a KerberosDomain object. Each on-premises Active Directory domain is represented as a single KerberosDomain object in Azure AD.
![Security Security](/uploads/1/3/3/8/133879095/768114739.jpg)
For example, your organization has an Active Directory forest with two domains,
contoso.com
and fabrikam.com
. If you choose to allow Azure AD to issue Kerberos TGTs for the entire forest, there are two KerberosDomain objects in Azure AD. One KerberosDomain object for contoso.com
, and one for fabrikam.com
. If you have multiple Active Directory forests, there is one KerberosDomain object for each domain in each forest.You need to run the steps to Create Kerberos server object in each domain and forest in your organization that contain Azure AD users.

Where can I go to find compliant Security Keys?
What do I do if I lose my security key?
You can remove keys from the Azure portal by navigating to the Security info page and removing the security key.
I'm not able to use FIDO immediately after I create a hybrid Azure AD joined machine
If clean installing a hybrid Azure AD joined machine, after the domain join and restart process you must sign in with a password and wait for policy to sync before being able to use FIDO to sign in.
- Check your current status by typing
dsregcmd /status
into a command window and check that both AzureAdJoined and DomainJoined are showing YES. - This delay is a known limitation for domain joined devices and isn't FIDO-specific.
I'm unable to get SSO to my NTLM network resource after signing in with FIDO and get a credential prompt
Make sure enough domain controllers are patched to respond in time to service your resource request. To check if you can see a domain controller that is running the feature, review the output of
nltest /dsgetdc:contoso /keylist /kdc
.Next steps
We have been on a journey to eliminate passwords. Today, we are delighted to announce an important milestone.
Microsoft has been aligned with the Fast Identity Online (FIDO) working group from the start, the alliance represents 250 organizations from various industries on a joint mission to replace passwords with an easy to use strong credential. With the recent ratification of FIDO2security keys by the FIDO working group, we’re updating Windows Hello to enable secure authentication for many new scenarios.
Imagine a helpdesk scenario where an employee can walk up to any device and simply log in using Windows Hello and not username and password. Another scenario is hospital medical staff that need access a patient records on a device no matter where the patient is located. Or a public-sector organization that wants secure authentication on devices while adhering to security policies and directives where the users credential needs to be physically separate from the device itself.
Microsoft and its partners have been working together on FIDO2 security keys for Windows Hello to enable easy and secure authentication on shared devices. Security keys allow you to carry your credential with you and safely authenticate to an Azure AD joined Windows 10 PC that’s part of your organization. A user can walk up to any device belonging to the organization and authenticate in a secure way – no need to enter a username and password or set-up Windows Hello beforehand. Unlike traditional passwords, these keys rely on high-security, public-key cryptography to provide strong authentication. These keys have all the benefits of a Trusted Platform Module (TPM) while also being portable enabling the increasing number of mobile workers.
FIDO2 compliant security keys provide secure authentication, independent of the form factor. The security key holds your credential and can be protected with an additional second factor like fingerprint (integrated into the security key) or a PIN to be entered at the Windows sign-in.
Our partners are working on a variety of security key form factors. Some examples include USB security keys and NFC enabled smartcards, just to name a few. We are looking forward to seeing new form factors and possibly applications on your phone that comply with the FIDO2 specification.
