SFA versus MFA in 365 sign in logs

Steel Contributor

all of our users have enforced MFA

 

Issue is that when you look at the sign-in logs there are SFA entries

 

all sign in should be MFA

 

what causes the SFA logs?

 

any known fix?

 

tnx

Have you disabled Legacy authentication across all users/workloads? PowerShell scripts, devices sending email, third-party aps - all will default to using legacy auth/single factor.
