Help me understand
This is an honest question, please don't take the piss as I am sure other people here would like an explanation as well.
Firstly Basic Authentication. I take this to mean username and password sent to a server from a device. The username and password are stored on the device / email client or maybe a copier. It's a simple case of entering these details once and the device will remember them. This does not mean that the details are sent in plain text but encrypted during transit if using the correct protocols, TLS or Starttls etc.
How does modern auth improve on this? How is the device initially configured if not with a username / password?
