The best way to protect yourself from hackers (Unwanted login) is to not only update your passwords, but to also make sure you're choosing strong passwords that can't be easily discovered.

Here are some tips and tricks to help you create reliable passwords that are impossible to guess:


1). 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.


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

Character category
Examples
Uppercase letters
A, B, C

Lowercase letters
a, b, c

Numbers
0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Symbols found on the keyboard (all keyboard characters not defined as letters or numerals) and spaces
` ~ ! @ # $ % ^ & * ( ) _ - + = { } [ ] \ | : ; " ' < > , . ? /


3). 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.


4). 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.


Conclusion
A password might meet all the criteria above and still be a weak password. For example, Hello2U! meets all the criteria for a strong password listed above, but is still weak because it contains a complete word. H3ll0 2 U! is a stronger alternative because it replaces some of the letters in the complete word with numbers and also includes spaces.

Help yourself remember your strong password by following these tips:

1. Create an acronym from an easy-to-remember piece of information. For example, pick a phrase that is meaningful to you, such as My son's birthday is 12 December, 2004. Using that phrase as your guide, you might use Msbi12/Dec,4 for your password.

2. Substitute numbers, symbols, and misspellings for letters or words in an easy-to-remember phrase. For example, My son's birthday is 12 December, 2004 could become Mi$un's Brthd8iz 12124 (it's OK to use spaces in your password).

3. Relate your password to a favorite hobby or sport. For example, I love to play badminton could become ILuv2PlayB@dm1nt()n.

If you feel you must write down your password in order to remember it, make sure you don't label it as your password, and keep it in a safe place.
