what is the difference between Basic Authentication and Windows Authentication in IIS 10.0?

My understanding of it is:

  • with Basic, a user at a client must enter a username/password that exists on the server (can be a local or AD user acct)
  • these credentials are sent in cleartext (not secure)
  • if there is a match, the website can be accessed
  • with 'Windows Authentication', a user at a client has his/her credentials sent with the website request in encrypted format
  • if that user acct exists in the server's AD domain, access is granted (so in this case, no login prompt appears)... if not (meaning user is not logged in with a domain acct), user gets a login prompt asking for a username/password of an AD user on the server - if correct (a match), access is granted

Is this correct?

  • in both cases, authentic'n is against known Windows accts
  • or could it be that 'Basic' can authenticate against user accts from another database or store?

Which is correct?
