How will Power Query in Excel handle MFA after September 15, 2025?
Starting September 15, 2025, Microsoft will enforce MFA by default for Microsoft 365 accounts. However, the actual application of MFA depends on your organization’s Entra ID (Azure AD) Conditional Access policies.
1. MFA is required, but IT can exclude specific accounts like service or break glass accounts.
2. Policies may make MFA conditional, such as only for risky sign ins or when accessing from external networks.
3. Trusted locations or compliant devices can minimize the frequency of MFA prompts.
So technically, your account could be excluded from MFA, but that depends entirely on how your organization’s policies are set up.Regards,

Hi VJoicic ,
rohit1991, explanation has made things clear, and your understanding is correct. The September 15, 2025 MFA enforcement will not affect how Excel Power Query works; prompts will still follow Entra ID policies and token expiry.
To keep refreshes smooth, it’s best to work with your IT team on Conditional Access settings. For unattended, automated refreshes without prompts, using Power BI or Fabric workflows is a good option.
Thank you for the clear explanation, rohit1991 .
Let us know if you see any unexpected MFA prompts after the policy changes.

Hi V-yubandi-msft ,
Thanks for the time and explanation.
With the Conditional Access settings after September 15th, would it be possible that my account is excluded from MFA, and it is up the our internal policies, or MFA will be strictly enforced for O365 accounts?
