Some users underestimate protection of their accounts and passwords.Using any shared computer or connection (RDP, VPN, VPS, proxy, etc.) is always a security risk.This is related to all programs which store any sensitive data (browsers, downloaders, file host managers ...)!
My program protects your settings including accounts but its default protection is limited.
Therefore there was program password protection in Settings - Misc - 2.
Update to version 6.9.9 is recommended. You will find a new item "Security" in Settings.
You can set encryption password. Program will encrypt all your accounts in the settings file with
a very strong encryption mechanism. This will protect your settings file from being stolen.
Note that this can't protect your data if anyone spies on your connection - use SSL secured sites (HTTPS).
Always protect your settings file (it has the ".nast" extension), do not upload it to public, do not share it,
do not leave it on any computer which you have abandoned.
