How Modern Authentication Works for Office 2016 / 2013. In September of 2019, Exchange Online announced its deprecation of Basic Authentication, prior to removal on October 13, 2020. How is the application authenticated when communicating with Azure platform services? Lucas Miller. Authorization methods: Microsoft's implementation of Open Authorization (OAuth). on 1 Apr 2022 9:00 AM. Modern authentication solutions including passwordless and multifactor authentication increase security posture through strong authentication. Synchronization is blocked by default in the default Azure AD Connect configuration. When the identity is enabled, Azure creates an identity for the instance in the Azure AD tenant that's trusted by the subscription of the instance. Open the Sign-in logs blade. Modern authentication is an umbrella term for a combination of authentication and authorization methods between a client (for example, your laptop or your phone) and a server, as well as some security measures that rely on access policies that you may already be familiar with. Here are the resources for the preceding example:: The design considerations are described in Integrate on-premises Active Directory domains with Azure AD. In the broker app scenario, after you attempt to sign in to Outlook for iOS and Android, ADAL will launch the Microsoft Authenticator app, which will make a connection to Azure Active Directory to obtain the token. A previously granted access token is valid until it expires. Grant access requests based on the requestors' trust level and the target resources' sensitivity. This means applications are now required to authenticate using what Microsoft terms 'modern' authentication, or OAuth2. Don't synchronize high-privilege accounts to an on-premises directory. How to configure Hybrid Modern Authentication Step 1. Finally, give notice and guidance to users about upgrading before blocking legacy authentication completely. The life cycle of a system-assigned identity is directly tied to the Azure service instance that it's enabled on. It's available for Office 365 hybrid deployments of Skype for Business server on-premises and Exchange server on-premises, and split-domain Skype for Business hybrids. The recommended way is to enable Managed Identities during cluster configuration. When one method isn't available for a user during sign-in or SSPR, they can choose to authenticate with another method. Originally published: March 2, 2020 Now to setup a new SAML policy on the ADC, go to Security - AAA Appication Traffic - Policies - Authentication - Basic Policies - SAML - Servers and click Add. Don't assume that API URLs used by a workload are hidden and can't get exposed to attackers. The Modern Authentication authorization model is provided by the Azure Active Directory service to integrate managed API applications with the same authentication model used by the Office 365 software REST APIs. For more information, see How to enable cross-app SSO on iOS using ADAL. Respecting the data security and compliance policies of our largest and highly regulated customers is a key pillar to the Microsoft 365 and Office 365 value. Keep your cloud identity synchronized with the existing identity systems to ensure consistency and reduce human errors. The following additional verification methods can be used in certain scenarios: To get started, see the tutorial for self-service password reset (SSPR) and Azure AD Multi-Factor Authentication. Ensure that you have entered an Admin Name and Admin Password. When you sign in with a passwordless method, credentials are provided by using methods like biometrics with Windows Hello for Business, or a FIDO2 security key. The policies must be enforced for all admins and other critical impact accounts. Outlook for iOS and Android offers a solution called AutoDetect that helps end-users quickly setup their accounts. The first step is to enable Modern Authentication, but after we have enabled it we will need to phase out the basic authentication methods. For all new Azure workloads, standardize on using managed identities where applicable. Also, modern protocols like OAuth 2.0 use token-based authentication with limited timespan. For users enrolled in Microsoft Intune, you can deploy the account configuration settings using Intune in the Azure portal. Reduce user-visible password surface area, Eliminate passwords from the identity directory, Passwordless authentication. By signing in once using a single user account, you can grant access to all the applications and resources per business needs. The following table outlines when an authentication method can be used during a sign-in event: * Windows Hello for Business, by itself, does not serve as a step-up MFA credential. A user-assigned managed identity is created as a standalone Azure resource. The best way to do that is to log into the Azure Active Directory portal and navigate to "Sign-ins". Important You can use any Microsoft user to create the application, it doesn't require application owner is administrator in your Office365 domain. Passwordless authentication removes the need for the user to create and remember a secure password at all. To learn more about self-service password reset concepts, see How Azure AD self-service password reset works. April 2021 MYOB Advanced has now added Azure Modern Authentication, I've managed to get it working for a single account using an Exchange SMTP/IMAP/POP external application and an Azure AD app, however it will only let me link it to a single email account! Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The access token grants Outlook for iOS and Android access to the appropriate resources in Microsoft 365 or Office 365 (for example, the user's mailbox). Capabilities like Windows Hello for Business or FIDO2 security keys let users sign in to a device or application without a password. Create the Application Sign into the Azure portal with a user ID with sufficient permissions to create an app. The life cycle of a user-assigned identity is managed separately from the life cycle of the Azure service instances to which it's assigned. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. See "Step 2 - Configure an Azure AD conditional access policy for Exchange Online with Active Sync (EAS). Basic Authentication relies on sending usernames and passwords -- often stored on or saved to the device -- with every request, increasing the risk of attackers capturing users' credentials, particularly if not TLS protected. This is an authoritative, deep-dive guide to building Active Directory authentication solutions for these new environments. Configure Azure AD Conditional Access by setting up Access policy for Azure management based on your operational needs. 1st Edition. To use Office 365 modern authentication follow these steps: If you are using Active Directory Federation Services (ADFS), then first review the caveats with modern authentication published here. The user can be prompted for additional forms of authentication, such as to respond to a push notification, enter a code from a software or hardware token, or respond to an SMS or phone call. 1. This evaluation is important, as it defines the technical requirements for how user identities will be created and maintained in the cloud. Pass-through Authentication requires that password writeback enabled in AAD Connect. Conditional access describes your authentication policy for an access decision. If a user is already signed in to another Microsoft app on their device, like Word or Company Portal, Outlook for iOS and Android will detect that token and use it for its own authentication. Managed Identity can help an API be more secure because it replaces the use of human-managed service principals and can request authorization tokens. New users will see their account in the initial account setup screen. In general, passwordless protections are preferred. This authentication protocol is more secure than the legacy Basic Authentication. That configuration assigns an identity to the cluster and allows it to obtain Azure AD tokens. Here are the resources for the preceding example: GitHub: Azure Kubernetes Service (AKS) Secure Baseline Reference Implementation. UW has blocked legacy authentication for all users in the UW Azure AD as of 9/6/2022. Important: In a production environment, in addition to the ClientId, Scope and redirectURI (step 2) you should generate from the Client App a challenge code too. Settings Tab - Schedule (Exchange/O365) - Enable Modern Authentication Enter the following information in the appropriate fields: Enter the email address associated with the Microsoft Exchange scheduling calendar in the Exchange Calendar Email Address text field. The only information the user needs to enter to complete the setup process is their password. Consistency of identities across cloud and on-premises will reduce human error and resulting security risk. Use PowerShell to enable your Exchange Online service for modern authentication and Skype for Business Online. Don't use custom implementations to manage user credentials. When such a token is detected, users adding an account in Outlook for iOS and Android will see the discovered account available as "Found" under Accounts on the Settings menu. Sahil Malik explains the basic business needs that led to the development of modern authentication, as well as the foundational concepts and protocols of mod. A mobile application can be decompiled and inspected. One of the main features of an identity platform is to verify, or authenticate, credentials when a user signs in to a device, application, or service. In Azure Active Directory (Azure AD), authentication involves more than just the verification of a username and password. This is in contrast with the term "modern authentication" which provides more security and capabilities. In this case, the token is stored in app shared storage. Attackers constantly scan public cloud IP ranges for open management ports. From the Overview page, click the 'App registrations' link under the Manage section. 0 Likes Reply Please go here for the latest. For information on token lifetimes, see Configurable token lifetimes in Microsoft identity platform. Azure AD supports these protocols, and the various endpoints can be seen by clicking the "endpoints" button on any app page in the Azure . Office 365 Exchange Online is a modern application and capable of using both modern and legacy authentication. We can see there is still some legacy authentication being used. For more information, see Implement password synchronization with Azure AD Connect sync. Book description. Notice the new Export and Import. Modern authentication is an umbrella term for a combination of authentication and authorization methods between a client (for example, your laptop or your phone) and a server, as well as some security measures that rely on access policies that you may already be familiar with. Upon token expiration, the client will attempt to use the refresh token to obtain a new access token, but because the user's password has changed, the refresh token will be invalidated (assuming directory synchronization has occurred between on-premises and Azure Active Directory). Also, require the same set of credentials to sign in and access the resources on-premises or in the cloud. Teams managing resources in both environments need a consistent authoritative source to achieve security assurances. To enable conditional access, understand what restrictions are required for the use case. Some companies have a requirement to capture all communications information within their corporate environment, and, ensure the devices are only used for corporate communications. This step enables you to filter the records based on the client application. Click on "Add Filter" and select the "Client-app" radio . Microsoft Authenticator is an example of a broker app. For example, an Azure Kubernetes Service (AKS) cluster needs to pull images from Azure Container Registry (ACR). Azure configuration 2. After the identity is created, the credentials are provisioned onto the instance. Next, click on Azure Active Directory Sign-in logs. For more information, see Azure AD Conditional Access support for blocking legacy auth. Verify Exchange related SPNs Step 6. . Modern authentication refers to authentication established by protocols that are better designed for Internet scale and management. Some authentication methods can be used as the primary factor when you sign in to an application or device, such as using a FIDO2 security key or a password. Tokens can be shared and reused by other Microsoft apps (such as Word mobile) under the following scenarios: When the apps are signed by the same signing certificate, and use the same service endpoint or audience URL (such as the Microsoft 365 or Office 365 URL). Implement conditional policies in Office 365/Azure AD to block "Rich Client" traffic (allow . For example, an MFA Challenge from Sign-in Frequency or SAML Request containing forceAuthn=true. Azure AD Multi-Factor Authentication (MFA) adds additional security over only using a password when a user signs in. When you see the Sign-in logs, click on Add filters Client app Apply. From the Azure services table, click the 'Azure Active Directory' icon. Instead, use Azure AD or other managed identity providers such as Microsoft account Azure B2C. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Office 2016 clients support modern authentication by default, and no action is needed for the client to use these new flows. Where possible, use authentication methods with the highest level of security. Modern Authentication is based on Active Directory Authentication Library and OAuth 2.0. Multi-factor authentication is a process where a user is prompted during the sign-in process for an additional form of identification, such as to enter a code on their cellphone or to provide a fingerprint scan. Modern authentication protocols support strong controls such as MFA and should be used instead of legacy authentication methods. In summary, we announced we were postponing disabling Basic Auth for protocols in active use by your . For example, MFA is a necessity for remote access; IP-based filtering can be used to enable adhoc debugging (VPNs are preferred). More info about Internet Explorer and Microsoft Edge, tutorial for self-service password reset (SSPR), How Azure AD self-service password reset works, How Azure AD Multi-Factor Authentication works, Hybrid integration to write password changes back to on-premises environment, Hybrid integration to enforce password protection policies for an on-premises environment. Azure AD can be used to authenticate Windows, Linux, Azure, Office 365, other cloud providers, and third-party services as service providers. Confirm EvoSTS auth server object is present Although the latter should be enabled for all tenants by now, I suggest you check the config just in case: Get-OrganizationConfig | select OAuth2ClientProfileEnabled And it might also be blocked client side via GPO/reg keys. There are three scenarios: For a federated identity model, the on-premises identity provider needs to send password expiry claims to Azure Active Directory, otherwise, Azure Active Directory will not be able to act on the password expiration. Verify OAuth virtual directories Step 7. How is user authentication handled in the application? Self-service password reset works in the following scenarios: When a user updates or resets their password using self-service password reset, that password can also be written back to an on-premises Active Directory environment. ADAL-based authentication uses OAuth for modern authentication-enabled accounts (Microsoft 365 or Office 365 accounts or on-premises accounts using hybrid modern authentication). If you use a password as the primary authentication factor, increase the security of sign-in events using Azure AD Multi-Factor Authentication. That then broke Outlook being able to connect until I re-enabled Outlook desktop (MAPI . For monitoring, if identity can be determined without an intermediate mapping process, security efficiency is improved.
