Two-Factor Authentication (2FA) for Office 365


Office 365 Two-Factor Authentication (2FA) or Multi-Factor Authentication is the process of secure Authentication in which a user or an organizational employee have to provide two factors to gain the access to Office 365 data. Microsoft Office 365 Two-Factor Authentication starts with user submitting his traditional username and password. Once user successfully gets authenticated with the 1st step verification, configured 2FA (OTP over SMS, Push Notifications, Google Authenticator, Microsoft Authenticator etc) method prompts on for 2nd-step verification. After successfully authenticating with both of the steps a user is granted with the access to the Office 365 resources. This additional layer prevents the unauthorized person from accessing the resources even if cyber attackers get to know your credentials.


miniorange provides 15+ Multi-Factor Authentication (MFA) methods and solutions for various use cases. It allows users and organization to setup certain authentication and settings which includes password restrictions, restricting sign-in methods, as well as other security settings. miniorange also make way for authentication apps that support Time-Based One-Time Password (TOTP) Google Authenticator, Microsoft Authenticator, Authy 2-Factor authentication app and our own miniorange Authenticator app. Follow the given guide to setup Office 365 MFA.


Connect with External Source of Users


miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Shibboleth, Ping, Okta, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more.
