Why a password alone is not enough
An employee receives a convincing sign-in page and enters a password. If that password is stolen, you want another check before someone can open business email or documents. Multi-factor authentication (MFA) asks for more than a password. In Microsoft 365, Microsoft Entra ID manages access and authentication methods.
MFA methods offer different protection
An additional sign-in step reduces the risk of account misuse. However, codes can be intercepted and users can approve misleading requests. Phishing-resistant methods such as FIDO2 passkeys are designed to bind sign-in to the correct website or application. The appropriate method also depends on your devices and users.
Make access practical for employees
Radorfa reviews the accounts, devices and applications in use. We then discuss the sign-in method, registration and support. Consider colleagues changing phones, shared workplaces and recovery if a security key is lost. Record who checks and handles these requests.
Test before a wider rollout
Start with a limited group. Ask colleagues to perform their normal tasks: sign in to Outlook, Teams and a business application. Also check what happens with an unfamiliar device or a lost authentication method. Update instructions before the next group switches. This keeps the technology connected to daily work.
MFA is part of your security approach
MFA does not replace access management, updates, monitoring or recovery planning. A compromised device or stolen session may create a different risk. Document the permissions needed, how suspicious sign-ins are assessed and who helps users. A single security setting does not demonstrate that the organisation meets every legal requirement.
