In order to reset the password from the admin/client user interface,
an SMTP configuration must be added and the user/admin must have an email
address.
You can prohibit the reset functionality on a per-user basis by using a
specific restriction.
Fixes#597
The builtin two-factor authentication is based on time-based one time
passwords (RFC 6238) which works with Authy, Google Authenticator and
other compatible apps.
If you prefer to auto-create the first admin you can enable the
"create_default_admin" configuration key and SFTPGo will work as before.
You can also create the first admin by loading initial data: now you can
set both username and password, before you could only change the password
