How to create a strong password?

1. Make it long
   This is the most critical factor. Choose nothing shorter than 15 characters, more if possible
   
   
2. Use a mix of characters
   The more you mix up letters (upper-case and lower-case), numbers, and symbols, the more potent your password is, and the harder it is for a brute-force attack to crack it
   
   
3. Avoid common substitutions
   Password crackers are hip to the usual substitutions. Whether you use DOORBELL or D00R8377, the brute force attacker will crack it equally easily. Random character placement is much more effective now than common leetspeak* substitutions. (*leetspeak definition: an informal language or code used on the Internet, in which numerals or special characters often replace standard letters)
   
   
4. Don’t use memorable keyboard paths
   Much like the advice above, do not use sequential letters and numbers or sequential keyboard paths (like qwerty). These are among the first to be guessed
   
   
5. Try to avoid using personal information
   Personal public information could be easily accessed online; therefore, to create a strong password, it is advised to avoid using information that could be linked to you (names, cities, birth dates, street addresses, pet names, favourite movies/books/sports teams, etc.).
