While thinking about preventing ransomware attacks on my machine I stumbled across the following question:
Assume I'm on a Windows (10) PC.
Assume further that I have two (local) accounts, one with admin privileges and one without where the second is the one I use day-to-day.
Now assume that both accounts use the same login credentials.
Is this as secure (against malware and such) as using different credentials?
If needed (I prefer a general answer) it may be assumed that the shared credential is a smart card (using different certificates for both accounts).
Please note: The threat model only includes things that can happen while the (standard) user is logged on. I totally understand that if somebody can get hands on the credentials he'll be able to just log-in as admin.
