How Long Should Your Password Be? The Latest Security Recommendations
Discover current security standards for password length and why longer passwords are more secure.
Password Length: Current Recommendations
Security standards have evolved. Here's what experts recommend in 2026.
NIST Guidelines
The National Institute of Standards and Technology recommends:
- Minimum: 8 characters (absolute minimum)
- Recommended: 12-16 characters
- High security: 20+ characters
Why Length Matters More Than Complexity
A longer password with simple characters is often more secure than a short complex one:
- "correct-horse-battery-staple" (28 chars) > "P@ssw0rd!" (9 chars)
The Math Behind It
Each additional character exponentially increases cracking time:
- 8 characters: ~2 hours to crack
- 12 characters: ~3 years to crack
- 16 characters: ~1 million years to crack
Passphrase Strategy
Consider using passphrases:
- Choose 4-5 random words
- Add numbers or symbols between them
- Make it memorable but not guessable
Example: "purple-elephant-42-dancing-moon"
