combination of upper case letters, Lower case letters, Symbols and numbers.

Hackers mainly use dictionary attack or brute
force attack first to crack your password and if they are failed in both
attacks they use Phishing attack which hacks your mind. Human mind is the

· How to surf internet safely (Anonymous)?
You should
surf internet anonymously so you will be safe & secure and it ensure that
your privacy is protected. No one is able to track you and you should not post
your personal information on Internet because internet is a public place. There
are many advantages of staying anonymous. For staying anonymous you need to use
a VPN (Virtual Private Network) which hides you and I would suggest you to use
Tor Browser instead of Chrome Browser because tor browser hides your identity
over internet by using proxies. If you want to use a paid VPN you can use Nord
VPN otherwise if you want to use a free one you should use Proton VPN because
it is best free VPN.
