Have you been looking for “Microsoft has enabled security defaults to keep accounts secure”? Then you are at the right place. Here you will read everything on it. 

Through the Azure portal, you activate security defaults. As Microsoft has enabled security defaults, all enterprises should have a fundamental level of protection enabled at no additional expense. Let’s know more about this in this article.

Microsoft has said that beginning in late June 2022, all active Azure Active Directory (Azure AD) tenants would have more stringent security default settings, or “security defaults,” enabled by default. To know more about Microsoft enabling security defaults, keep on reading. 

Microsoft has set security defaults to protect account security

In your Azure AD directory and Office 365 environment, the recently released Azure security defaults simplify deploying some of the most popular security settings. Not everyone should use them, but if you haven’t turned off traditional Authentication or activated multi-factor Authentication yet, you should give it some thought.

Conditional Access allows for the authorization of various people, programs, managed and unmanaged devices, places, and levels of Security. However, the lowest common denominator has been considered while designing the default settings for an Office 365 tenancy: companies with existing clients.

Businesses are also expected to purchase add-on security capabilities, like EM+S, if they want protection. Because an attacker can repeatedly try to log in to an Office 365 tenant using simple scripting, and if they are successful, authenticate with a username and password, there is no MFA mechanism in place. Many Office 365 tenants are vulnerable to several attack vectors, including password spray attacks.microsoft security Whether you’ve paid for an Azure AD Premium license or not, Security Defaults take the role of Baseline Conditional Access rules. They are available for free to all Office 365 subscribers. This is a shift since while per-user MFA can be enabled in Office 365, it needed the Authenticator app or the simple enabling process that Conditional Access or service-wide Azure MFA had.

Security Defaults enforce these settings

These are the setting enforced by security defaults:default

  • Administrators and end users must utilize multi-factor Authentication within 14 days of the enabling date for the next sign-in.
  • Disabling legacy authentication will limit Access from older clients, including Office 2010, POP3, SMTP, IMAP, ActiveSync clients that don’t support Modern Auth, and traditional ways of managing Exchange Online through Remote PowerShell.
  •  For “privileged” Azure AD actions, instant MFA protection is available through the Azure Resource Management API.

What impact may this have on new Office 365 migrations?

Even if you don’t use IMAP and POP3 clients or more outdated clients like Office 2010, you could be surprised if you sign up for an Office 365 subscription in the coming months and Microsoft security defaults are turned on.

Even if you used the most recent version of Office 365 Pro Plus and logged in to Office 365 for licensing, you can still have a problem with Microsoft 365 security defaults activated. Outlook clients are one instance of this. When you move a mailbox, Outlook should instantly reconnect to Exchange Online and reconfigure itself.office 365 This is because when a mailbox is migrated, it uses the traditional authentication method. At the same time, it travels via the Autodiscover bread trail to Exchange Online and then has difficulties when attempting to sign in. If you have authority over your Outlook clients, deploy the registry key described in this article to fix the issue by turning off Security Defaults during your migration.

Moreover, ActiveSync clients may be found on iOS devices. The Gmail and Samsung Mail applications also support Modern Authentication; however, you must modify those clients. But, if you are utilizing the most recent office 365 security defaults Pro Plus clients and the Office applications on mobile, you should anticipate experiencing only a few technical difficulties.

Yet, the user effect of requiring MFA everywhere may be the most important aspect.

No substitute for Azure AD Conditional Access

The inconvenience to users is a drawback of multi-factor Authentication. Of course, this is essential for unidentified devices in unknown places. Still, most businesses spend a lot of time and money ensuring their devices and locations are safe, so they have confidence in them.

It is at this point that Azure AD Conditional Access is still crucial. Conditional Access allows for the authorization of various people, programs, managed and unmanaged devices, places, and levels of Security. You may decide where and when to activate MFA or even prohibit Access.

For instance, you may do away with the need for users to check in from their domain-joined Windows 10 PCs when using Office 365 Premium Plus on their office computers to verify that it is them using the Microsoft Authenticator app.azure ad You may also eliminate routine MFA prompts on your company-issued mobile phone and instead properly manage the device with the help of programs like Intune. Yet, if they are using laptops provided by the employer to work from home, you could occasionally need them to sign in. You may even completely forbid unmanaged devices from using random web browsers to sign in to services with critical corporate data.

There are many more conditional access cases than described above, but those are some of the main ones, and Security Defaults don’t address them.

The most unfortunate aspect of Security Defaults is that it needs the most fundamental capability that businesses want. 

As they have simple use cases, such as shop-floor workers in manufacturing where employees are not authorized mobile devices, upgrading Azure AD Premium for each user will only be worthwhile for such employees in some firms. We’ll likely observe those firms being unprotected in those situations.

Microsoft may introduce the fundamental trustworthy IP address range for avoiding MFA, similar to what they did with the Authenticator app. Now let’s look at how Microsoft has enabled security defaults.

Enabling and Disabling the Security Defaults

If you aren’t utilizing Conditional Access right now, you can activate Security Defaults as Microsoft has enabled security defaults. Activating Security Defaults won’t be available if you have CA policies.

Before taking any action, be careful to notify users so they know of the impending change and that Access from legacy clients or programs won’t be blocked. There are no exceptions for users or old apps as it is an all-or-nothing switch, unlike conditional access, which allows exceptions.disable seacurity To activate Security Defaults, log in to the Azure AD Portal as a Global Administrator. Then, go to Azure Active Directory and scroll down to Properties. From there, you can activate Security Defaults. Next, choose Manage Security Defaults.

When that happens, you can choose to activate Security Defaults. You can enable or disable it using an on/off switch. So turn off security defaults in office 365. 

Security Defaults are great because you can define your Conditional Access (CA) policies without turning them off. This means you don’t have to waste time disabling Security Defaults before configuring your CA policies. Instead, you can keep them enabled and set your policies as needed. This saves you time and effort. You can simply leave Security Defaults enabled and set your CA policies as needed. After configuring the CA rules, the system will inform you that you can continue. After finishing, you can disable Security Defaults and enable your CA policies. So this is how to turn off Microsoft authenticator

When Security Defaults is on, disabling MFA for a particular user or user is regrettably not feasible. All users inside a tenancy have MFA enabled after enabling Security Defaults.


We hope you understand why Microsoft has enabled security defaults with this article. The system will deny all previous protocol authentication requests once you set up the security parameters for your tenant. Microsoft’s move to enable Security Defaults is a great first step in helping all customers secure their identity.
