Legacy authentication protocols present significant vulnerabilities, as they bypass modern security controls including MFA. Blocking these outdated protocols prevents attackers from exploiting this common weakness while encouraging users to adopt modern, secure authentication methods.
Choosing the Right Authentication Methods
The Microsoft Authenticator app provides passwordless sign-in capabilities, eliminating passwords as a potential weakness while streamlining the user experience. This method works particularly well for tech-savvy teams comfortable with smartphone-based authentication.
Phone call and SMS options serve users without smartphones or in areas with limited app functionality. While less secure than app-based methods, these options ensure universal MFA coverage across your organization. Security keys utilizing FIDO2 standards offer phishing-resistant authentication ideal for highly privileged accounts.
We recommend hardware tokens for administrative accounts with broad M365 permissions. The additional security justifies the minimal hardware investment, particularly for accounts that could compromise your entire tenant if breached. Balancing these options based on user roles and risk profiles prevents circumvention while maintaining strong security.
