Multi-factor Authentication (MFA) is an authentication method which is used to ensure that digital users are who they say they are proving two or more verification factors to gain access to a resource such as an application, online account, or a VPN. MFA requires one or more additional verification factors, which decreases the likelihood of a successful cyber-attack. If one of the factors has been compromised by a hacker or unauthorized user, the chances of another factor also being compromised are low, so requiring multiple authentication factors provides a higher level of assurance about the user’s identity. One of the most common MFA factors that users encounter are one-time passwords (OTP). OTPs are those 4-8-digit codes that you often receive via email or SMS. With OTPs a new code is generated periodically or each time an authentication request is submitted.
In short
Multi-factor authentication (MFA) requires a second proof of identity, such as an authenticator app approval, a passkey or a FIDO2 security key, in addition to a password. emtech plans and deploys MFA for UAE organisations on Microsoft Entra ID, covering Microsoft 365, VPN, remote access and business applications, with conditional access policies and a phased rollout so staff are not locked out.
It is better than a password alone, but it is the weakest common method. SMS codes can be phished, intercepted or redirected through SIM swap fraud. Use it only as a fallback for general staff and never for administrators or users who approve payments.
MFA fatigue is when an attacker with a stolen password sends repeated push requests until the user approves one to make them stop. Number matching, which Microsoft Authenticator now uses by default, largely prevents it because the user must type a number shown on the sign-in screen. Alerts on repeated denied requests and phishing-resistant methods for high-risk users close the gap further.
Yes. VPNs that support SAML can use Entra ID sign-in with conditional access, and RADIUS-based VPNs can add Entra MFA through the NPS extension. Remote desktop access is usually protected through a gateway or PAM platform that enforces MFA before the session opens.
The helpdesk verifies the person's identity, removes the old method and issues a temporary access pass so they can register a new device. Users with a second registered method, such as a security key, can recover themselves. The verification step matters because attackers use fake lost-phone calls to take over accounts.
Conditional access requires Microsoft Entra ID P1, which is included in Microsoft 365 Business Premium, E3 and E5. Organisations without P1 can use security defaults, which enforce MFA but offer no granular policies. Risk-based policies need Entra ID P2.
No. Proxy phishing can steal a session after MFA completes, users can be tricked into granting consent to malicious apps, and helpdesk social engineering bypasses MFA entirely. Phishing-resistant methods, device-based conditional access and helpdesk verification address these.
For a typical Microsoft 365 organisation, the rollout runs over a few weeks: a week or so for readiness and design, a pilot, then department-by-department enforcement. VPN and application integrations and hardware key distribution can extend the timeline.
Having Multi-factor Authentication will enhance your organization's security. Multi-factor authentication provides a layer of protection for both employees and customers. Cyber criminals spend their lives trying to steal your information and an effective and enforced MFA strategy is your first line of defense against them. An effective data security plan will save your organization time and money in the future.
