Description:

This article describes a simple way to estimate the size (in bytes) required for the PasswordData blob.

Solution:

The PasswordData blob can contain up to 32 history passwords.

It also contains:

• Login failures
  
  
• Last login time
  
  
• Previous login time
  
  
• Disabled time
  
  
• Last password change time

Each of them is taking up to 1024 bytes.

Therefore you should multiple the number of passwords to keep in the history by 1024, then add a buffer of a few more kilobytes.

So it makes 32.768 bytes + buffer. The PasswordData blob should have a max size of 40kB.
