Password policy reference

Modern guidance (NIST SP 800-63B) favors length over forced complexity. Entropy is what actually stops attackers:

Length vs entropy (full 95-char pool)

Length Entropy (bits) Typical use
8~40–52Barely acceptable for low-value accounts
12~63–79Baseline for everyday accounts
16~84–105Recommended for email, banking, password vault
20+105+Long-term secrets, master passwords, encryption keys

Values assume random generation. Human-chosen passwords have far less entropy per character (~2–4 bits) than random ones.

Edge cases worth knowing

  • Each +1 character multiplies the search space by the pool size — going from 12 to 16 chars is 30 million times harder to crack.
  • Excluding ambiguous characters (0/O, 1/l/I) removes ~8 symbols from the pool — slightly lower entropy, much easier to read aloud or retype.
  • A 5-word passphrase you can remember beats a 12-char random string you write on a sticky note.
  • Since a manager fills passwords in for you, use the full 95-character pool and 20+ characters — memorization is no longer a constraint.

Password Security Best Practices

Follow these guidelines to maintain maximum security for your accounts

Use Unique Passwords

Never reuse passwords across multiple accounts. Each account should have its own unique password.

12+ Characters

Use passwords with at least 12 characters. Longer passwords are exponentially harder to crack.

Enable 2FA

Use two-factor authentication whenever available for an additional layer of security.

Use Password Manager

Store passwords securely using a reputable password manager application.
