Microsoft Office Outlook Web Access (OWA) offers integrated time and information management solutions. E-mail, calendar management, task management, contact management, note-taking, journaling, and online surfing are just a few of the capabilities of Outlook that help with communication and organizing. Outlook helps you to search and categorize your mail, organize your work, and better share your information with others all from one handy spot. You can enable two-factor authentication for Outlook Web Access (2FA/MFA for OWA) managed active directory to increase the security level.
Two-Factor Authentication (2FA) or Multi-factor Authentication (MFA) is the process of authentication in which you have to provide two factors to gain access into a particular application. First Factor is the one that you know - username and password and Second factor is - what you might have as unique, like a phone (For OTP) or Fingerprint. When we integrate 2FA in OWA, this additional layer of security prevents the unauthorized person from accessing your Microsoft OWA Applications even if they know your username and password. miniOrange provides 15+ Multi-factor Authentication methods and solutions to secure your resources.
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.
