How to survive attacks that result in password leaks?

We speak about attacks on online providers that result in the leak
of personal users' passwords. Just recently we saw the leak of 6.46
million Linkedin
user passwordss. Right after this we saw a leak of 400 thousand Yahoo
Voices
passwords. These are not isolated cases; nowadays we
see many successful attacks that lead to personal data leaks. One
more example of this is the leak of personal information of users of
one of the popular Android
forums
and finally the hack of the NVIDIA
developer forum. It's worth saying that many successful attacks are
just not announced and the Internet community doesn't find out about
them.

So, how do we deal with cases when our passwords can be leaked?
Obviously the end user can't do much to protect his on-line service
provider and prevent the leak, but there are some basic tips on how
to avoid a big disaster when our passwords are compromised.

1. Use a different password for each different
online resource. Never reuse the same password for different
services. If you do, all or many of your other online accounts can
be compromised.
2. Use complex passwords. This means, in a perfect
scenario, a combination of symbols, letters and special characters.
The longer the better.
3. Sometimes our online service providers don't
let us create really complex passwords, but try to use long
passwords, with at least 23 characters in a combination of uppercase
and lowercase letters. A password of 23 characters (131 bits) would
be ok.

For some users it's hard to remember complex passwords, in which
case a good solution would be to use a password manager like Kaspersky
Password Manager
.

Remember, you can't stop your service provider being hacked, but you
can avoid a bigger disaster when all of your accounts get
compromised at once just because you used the same password!
