#### Authentication
|
|
|
|
By default this will serve files without needing a login.
|
|
|
|
You can either use an htpasswd file which can take lots of users, or
|
|
set a single username and password with the --user and --pass flags.
|
|
|
|
Use --htpasswd /path/to/htpasswd to provide an htpasswd file. This is
|
|
in standard apache format and supports MD5, SHA1 and BCrypt for basic
|
|
authentication. Bcrypt is recommended.
|
|
|
|
To create an htpasswd file:
|
|
|
|
touch htpasswd
|
|
htpasswd -B htpasswd user
|
|
htpasswd -B htpasswd anotherUser
|
|
|
|
The password file can be updated while rclone is running.
|
|
|
|
Use --realm to set the authentication realm.
|
|

|
|
|
|
// CustomAuthFn if used will be used to authenticate user, pass. If an error
|
|
// is returned then the user is not authenticated.
|
|
//

// If a non nil value is returned then it is added to the context under the key
