Dynamic user credential generation with Powershell for Basic Auth Implementation - powershell

Question

Requirement: Would like to have basic auth setup using custom php script.
Would like to :
Create user credentials dynamically
Create the cred php file with these credentials updated
Update the username & password to respective for Azure WebApp settings.
[ Note: FTPing the cred and auth files automatically if missing would be in upcoming post ]

Azure Powershell 4.0+
Windows Powershell ISE
Knowledge of Storage Account ( Name, RG's )
Knowledge of WebApp for which backup is desired ( WebApp Name and RG )
