Is basic access authentication secure?
Using Apache, it is quite simple to set up a page that uses basic access authentication to prompt a user for a name/password and use those credentials in some way to grant access to that user.
Is this secure, assuming the connection between the client and server is secure?
Answer
The worry about basic auth is that the credentials are sent as cleartext and are vulnerable to packet sniffing, if that connection is secured using TLS/SSL then it is as secure as other methods that use encryption.
