🛡️ Password Security Best Practices

📏

Use at least 16 characters. Length is the single most important factor. A 16-char password with only lowercase is far stronger than an 8-char password with all character types.

🔀

Mix character types. Combine uppercase, lowercase, numbers, and symbols. This dramatically increases the number of possible combinations (the "charset size").

🔑

Use a unique password for every account. If one site is hacked and your password is exposed, attackers will try it on every other service. This is called "credential stuffing."

🗝️

Use a password manager. Tools like Bitwarden (free), 1Password, or LastPass securely store all your passwords. You only need to remember one master password.

📵

Never use personal information. Birthdays, names, phone numbers, and pet names are easy to guess — especially for people who know you or can find you on social media.

📖

Avoid common passwords. "password", "123456", "qwerty", "iloveyou" are the first things hackers try. Over 80% of data breaches involve weak or reused passwords.

📱

Enable Two-Factor Authentication (2FA). Even if your password is stolen, 2FA prevents hackers from accessing your account without your phone or authenticator app.

🔄

Change passwords after breaches. Check haveibeenpwned.com to see if your email has appeared in data breaches. Change affected passwords immediately.

🧠

Use passphrases for master passwords. A random sequence of 4-5 words ("correct horse battery staple") is easy to remember but extremely hard to crack — stronger than most complex passwords.

🚫

Never share passwords via chat or email. Legitimate services will never ask for your password. Sharing via messaging apps is risky — use a secure password sharing feature in your password manager instead.

⚠️ Most Common Passwords to NEVER Use

📐 Password Security Math

Charset Size

Lowercase only (a-z): 26 characters
+ Uppercase (A-Z): 52 characters
+ Numbers (0-9): 62 characters
+ Symbols (!@#$%^&*...): 94 characters

Number of Possible Combinations

Combinations = Charset Size ^ Password Length

Example: 16-char password with 94 charset:
94^16 = 37,157,429,083,410,091,685,945,344 combinations
≈ 3.7 × 10^28 possible passwords

Password Entropy (bits)

Entropy measures unpredictability. Higher entropy = stronger password.

Entropy (bits) = log₂(Charset Size ^ Length)
= Length × log₂(Charset Size)

128-bit entropy is considered unbreakable.
A 20-char password with full charset has ~131 bits.

Time to Crack (Brute Force)

Crack Time = Combinations ÷ Guesses Per Second

Modern GPU: ~10 billion (10^10) guesses/second
Botnet: ~100 trillion (10^14) guesses/second

A 128-bit entropy password would take longer than
the age of the universe to crack even with a botnet.
