     SFTPGo supports groups to simplify the administration of multiple accounts by letting you assign settings once to a group, instead of multiple times to each individual user.
     The SFTPGo WebClient allows end users to change their credentials, browse and manage their files in the browser and setup two-factor authentication which works with Authy, Google Authenticator and other compatible apps.
     From the WebClient each authorized user can also create HTTP/S links to externally share files and folders securely, by setting limits to the number of downloads/uploads, protecting the share with a password, limiting access by source IP address, setting an automatic expiration date.
