How to Create Strong and Secure Passwords

🔐Password entropy measures the information held in a password and its resistance to cracking.

💡A strong password is long, uses various character types, and cannot be easily guessed or found in a dictionary.

🔢Passwords with fewer than 8 characters are easily cracked, especially with powerful GPUs.

🔀Avoid common password substitutions like replacing 'e' with '3' and 'o' with '0'.

🔑Consider using multiple randomly chosen words, with or without symbol replacements, for a strong and memorable password.

What is password entropy?

—Password entropy measures the amount of information held in a password, indicating its resistance to cracking.

How long should my password be?

—Aim for a password length of at least 8 characters. Longer passwords are generally stronger.

Do I need to use symbols in my password?

—Using symbols adds complexity to your password, but it's not always necessary. Focus on length, uniqueness, and avoiding common patterns.

Should I reuse passwords for different accounts?

—Never reuse passwords. If one password is compromised, all accounts using that password become vulnerable.

What are the advantages of using a password manager?

—Password managers generate and store strong, unique passwords for all your accounts, eliminating the need to remember multiple passwords.
