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.

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:
- 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.
- 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).
- 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.
