Are there any unbreakable passwords?

Answer 1

No, the reason is that usually there are just two rules to play with to create a password: maximum length and allowable character set, so you need to use complexity to ensure not to select easily-guessed passwords. Weak passwords make it easy for intruders to break into your computer system, that is why you should use password strength rules, to reduce the vulnerability or your password thru guessing attacks. Some of these rules are:
# Use a minimum of 8 characters in the password length.
# The password must contain at least one characters from three of the following categories: uppercase letter, lowercase letter, numeric character and non-alphanumeric/special character (like ! % * + - / : ? _).
# Don't use your name/birthday date or the name/birthday date of a family member, Social Security Number, license plate, your favorite sports team or vacation spot. Also don't reverse or rearranged the letters in your name in any way.
# Try to avoid the use of repeating characters, dictionary words or derivatives.
# Your new password should not be a permutations of your old one and avoid using your last 3 passwords.
# Passwords must be replaced periodically: at least once every 3 months, but change it whenever you want or when you feel your password has been compromised,
# Don't use the same password that you use for any other online or bank-related accounts and you should never write it down unless you place that written password in a very secure location. Your password is the key to accessing part of your identity. Keep it safe.

As attacks increased in sophistication, so should the rules for choosing your passwords and also remember that what is done under your password is your responsibility

Answer 2

Not unbreakable in a theoretical sense, but if you use one that's random characters and long enough, the effort to brute-force break it would be more than it's worth (and more than anyone except perhaps the government of a large nation could employ).

Google around for information, I remember seeing a website with a good description of this, I just don't remember what it is.

Most passwords that are cracked are because someone used their birthday, or a simple word or something like that.

Answer 3

No!
But you can make a password very much secure by using special characters,small & capital letters and number combination in your password!

If you use this your password will be highly secure and very difficult to crack!

So go and create a secure password so that no one can access your account!

Hav fun!
Bye!

Answer 4

No. As soon as you know a username and a password to go with it, you can gain access to whatever is hidden behind it!
