The Traditional Password Advice

According to the traditional advice—which is still good—a strong password:

  Has 12 Characters, Minimum: You need to choose a password that’s long enough. There’s no minimum password length everyone agrees on, but you should generally go for passwords that are a minimum of 12 to 14 characters in length. A longer password would be even better.

   Includes Numbers, Symbols, Capital Letters, and Lower-Case Letters: Use a mix of different types of characters to make the password harder to crack.

   Isn’t a Dictionary Word or Combination of Dictionary Words: Stay away from obvious dictionary words and combinations of dictionary words. Any word on its own is bad. Any combination of a few words, especially if they’re obvious, is also bad. For example, “house” is a terrible password. “Red house” is also very bad.

   Doesn’t Rely on Obvious Substitutions: Don’t use common substitutions, either — for example, “H0use” isn’t strong just because you’ve replaced an o with a 0. That’s just obvious.

Try to mix it up—for example, “BigHouse$123” fits many of the requirements here. It’s 12 characters and includes upper-case letters, lower-case letters, a symbol, and some numbers. But it’s fairly obvious—it’s a dictionary phrase where each word is capitalized properly. There’s only a single symbol, all the numbers are at the end, and they’re in an easy order to guess.

A Trick For Creating Memorable Passwords

With the tips above, it’s pretty easy to come up with a password. Just bash your fingers against your keyboard and you can come up with a strong password like 3o(t&gSp&3hZ4#t9. That’s a pretty good one—it’s 16 characters, includes a mix of many different types of characters, and is hard to guess because it’s a series of random characters.

The only problem here is memorizing this password. Assuming you don’t have a photographic memory, you’d have to spend time drilling these characters into your brain. There are random password generators that can come up with this type of password for you—they’re generally most useful as part of a password manager that will also remember the passwords for you.

You’ll need to think about how to come up with a memorable password. You don’t want to use something obvious with dictionary characters, so consider using some sort of trick to memorize it.

For example, you might find it easier to remember a sentence like “The first house I ever lived in was 613 Fake Street. Rent was $400 per month.” You can turn that sentence into a password by using the first digits of each word, so your password would become TfhIeliw613FS.Rw$4pm. This is a strong password at 21 digits. Sure, a true random password might include a few more numbers and symbols and upper-case letters scrambled around, but it’s not bad at all.

Best of all, it’s memorable. You just need to remember those two simple sentences.

The Passphrase / Diceware Method

Comic from XKCD

The traditional advice isn’t the only good advice for coming up with a password. XKCD did a great comic about this many years ago that’s still widely linked to today. Throwing all the usual advice out, the comic advises choosing four random words and stringing them together to create a passphrase—a password that involves multiple words. The randomness of the word choice and length of the passphrase makes it strong.

The most important thing to remember here is that the words need to be random. For example, “cat in the hat” would be a terrible combination because it’s such a common phrase and the words make sense together. “my beautiful red house” would also be bad because the words make grammatical and logical sense together. But, something like “correct horse battery staple” or “seashell glaring molasses invisible” is random. The words don’t make sense together and aren’t in grammatically correct order, which is good.  It should also be much easier to remember than a traditional random password.

People aren’t good at coming up with sufficiently random combinations of words, so there’s a tool you can use here. The Diceware website provides a numbered list of words. You roll traditional six-sided dice and the numbers that come up choose the words you should use. This is a great way to choose a passphrase because it ensures you use a random combination of words—you may even end up using words that aren’t a normal part of your vocabulary. But, because we’re just choosing from a list of words, it should be fairly easy to remember.

Diceware’s creators now recommend using at least six words because of advances in technology that make password-cracking easier, so keep that in mind when creating this sort of password.

Answer:

You must keep the following things in mind while choosing an effective password:

Explanation:

  • Create a long password
  1. Mostly, accounts created for online services are usually asked to create a password of 6-8 characters.
  2. A short password is easy to remember. But, this crack can also be done easily. So, create a password of at least 12 characters for any online account. Because the bigger your password is, the more difficult it will be to crack it.
  • Create an Alphanumeric password
  1. While creating your password, keep in mind that all the keys on the keyboard have been used in it.
  2. In the password, you should create a strong password for yourself with a combination of Alphabets (a,b,c), Numbers (1,2,3), Symbols (@,#,$,&), etc.
  • Do not Use Proper Words
  1. While creating a password, you should also keep in mind that you should not use dictionary words in a secure password.
  2. You may find this a bit strange. However, there should be no compromise with safety. So, you should use Misspell and Unmeaning full words instead of correct words.
  • New Account New Password
  1. In the digital world, we have to create separate accounts on different websites.
  2. But, we create the same password for different accounts. This mistake is not only you, but most people who are new to the online world make this mistake.
  3. If you have more than one account, you should create a new password for each new account. If you create the same password for all the accounts then all your accounts can be easily hacked if the password of one account is known.
