Can someone help me to get the strong authentication details from Azure AD for some users provided through input file.
Thanks in advance
There are dozens of such script samples available online, look them up. Since most of them require Global admin permissions, I'd recommend using the recently introduced auth methods report under: https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/PasswordReset
Or the corresponding Graph API endpoints if you want a programmatic solution.
