Simple .htaccess protection
Because I bet many of you that don't have knowledge about this kind of stuff wanted to know how is this done ... it's actually more simple than you think !
Put this in a file named ".htaccess" in a directory you want to be protected.
AuthType Basic AuthName "Password Required" AuthUserFile /full/path/to/your/.passwds Require valid-user
In the command line for the first user do this ( for all the other users you can drop the -c ) :
htpasswd -c .passwds dexter #New password: #Re-type new password: #Adding password for user dexter
