After signing in, you’ll be prompted to enter additional information. Choose Next and follow the prompts to configure SMS verification as your preferred MFA method. This will involve entering your mobile phone number, and Microsoft will send a verification code via text message.
When prompted, enter the verification code you received to complete the setup process. Moving forward, you must provide this code in addition to your password when logging in to your Microsoft 365 account each time.
Using MFA with SMS Text Messages offers several benefits, such as:
- Increased account security
- Reduced risk of unauthorized access
- Easier user verification when traveling (without incurring roaming fees)
However, some security experts recommend using alternative MFA methods, like the Microsoft Authenticator app, for even greater security. The choice ultimately depends on your organization’s needs and security policies.
Adding MFA to your Microsoft 365 account using SMS Text Messages is recommended to enhance account security. By following the setup process and regularly providing the necessary verification codes, you can keep your valuable data safe from unauthorized access.
