Password Generator: How to Create Strong, Secure Passwords

What Makes a Password Strong?

A strong password has two key properties: length and randomness. NIST (National Institute of Standards and Technology) guidelines from 2024 emphasize:

• Minimum 8 characters (they now recommend 15+).
• Use all character types: uppercase, lowercase, numbers, and symbols.
• No requirement to change passwords periodically (unless compromised).
• Check against breach databases (HaveIBeenPwned).

Password Entropy: The Mathematics of Security

Entropy measures password randomness in bits. Higher entropy means harder to crack:

Password	Length	Entropy	Crack Time (GPU)
password	8	~18 bits	Instant
P@ssw0rd	8	~52 bits	Minutes
Tr0ub4dor&3	11	~44 bits	Days
correct horse battery staple	28	~44 bits	Days
Random 16-char	16	~95 bits	Billions of years

How to Generate a Secure Password Online

1. Open FavorTool Password Generator.
2. Set length to 16+ characters for maximum security.
3. Enable all character types: uppercase, lowercase, numbers, symbols.
4. Click Generate — a cryptographically random password is created.
5. Copy it immediately and save to your password manager.

Password Manager vs. Memorizing Passwords

The best security practice is to use a password manager (Bitwarden, 1Password, LastPass) with a unique, randomly generated password for every account. You only need to remember one master password. Generated passwords should be completely random — the FavorTool generator uses the Web Cryptography API for true randomness.

Passphrases: A Human-Friendly Alternative

A passphrase — several random words strung together — can be both memorable and secure. "correct-horse-battery-staple" (from XKCD) is more secure than "Tr0ub4dor&3" and much easier to remember. Use the FavorTool generator's passphrase mode for this option.
