Hi @TekTrendz Tek ,
Welcome to Q&A forum!
Per my research, I haven not found any plans that require Multifactor Authentication on Office 365. You can enable MFA for Microsoft 365 and Office 365 in multiple ways as needed:
- With security defaults
- With Conditional Access policies
- For each individual user account (not recommended)
For more information about Multifactor authentication, please refer to:

Set up multifactor authentication
Hope the information is helpful to you.
