I have seen this comment below mentioned here:
You can disable the use of SSPR for administrator accounts using the Set-MsolCompanySettings PowerShell cmdlet. The -SelfServePasswordResetEnabled $False parameter disables SSPR for administrators.
Instead on disabling SSPR for all admin accounts, is it possible to disable SSPR to induvial admin accounts?
I already enabled sspr for my company for all users, the question is what is gonna happen if I disalbed it ? I will have issues ?
