Never.
When making passwords
make sure your password is at least ten characters long
and is completely random.
use a mixture of numbers, letters, both upper and lower case and use symbols.
when giving an answer to a security question,
never ever put an actual true answer.
make another password and use that.(again at least ten characters long)
write the passwords down and keep them in a safe place.
using at least ten characters it would take several years to crack the password,
thus making it non-profitable for any hacker to attempt to crack it.
99% of cracked passwords and accounts stolen or misused
are by someone the victim knows personally.
If you've ever wondered just how secure your favourite password is,
here's a simple web site that will tell you.
Just go to http://www.howsecureismypassword.net/ and start typing.
As you type, the indicator is updated after every character
to tell you, approximately,
how long someone on a single desktop PC would typically take to crack it.
You should always Avoid creating passwords that use:
Dictionary words in any language.
Words spelled backwards, common misspellings, and abbreviations.
Sequences or repeated characters. Examples: 12345678, 222222, abcdefg,
or adjacent letters on your keyboard (qwerty).
Also avoid creating passwords that use
Personal information. Your name, birthday, driver's license,
passport number, or similar information.
you can use this
Secure Password Generator > http://passwordsgenerator.net/
to help you create a proper password.
Just remember.
The easiest way to "remember" passwords is to write them down.
It is okay to write passwords down,
but keep the written passwords in a secure safe place.
you could also use a password manager to aid you.
LastPass > https://lastpass.com/
is free and after testing all the top 5 password managers,
this one came out on top for me.
one last thing,
make sure you use
any or all of the safety/security features if offered by whatever
site it is you are signing in to.
