Password Security in 2025: Beyond 'Complex' Passwords

The way we think about password security is changing. NIST's updated guidelines now recommend longer passphrases over complex passwords, and technologies like passkeys are beginning to replace passwords entirely. Here's what you need to know to stay secure in 2025.

Why Traditional Password Rules Are Wrong

For years, we were told to create passwords with uppercase letters, lowercase letters, numbers, and special characters. The result? People create predictable patterns like 'P@ssw0rd!' that are easy for computers to crack but hard for humans to remember. NIST now recommends using longer passphrases (16+ characters) that are meaningful to you but unpredictable to attackers.

The Essential Security Stack

• Password manager — generate and store unique passwords for every account (we recommend Bitwarden or 1Password)
• Multi-factor authentication (MFA) — require a second factor beyond your password for all important accounts
• Passkeys — where supported, use passkeys for passwordless authentication
• Breach monitoring — get alerts when your credentials appear in data breaches

For Businesses

Business owners should mandate MFA for all employee accounts, provide a company-wide password manager, implement single sign-on (SSO) where possible, and include password hygiene in regular security training. These steps alone can prevent the majority of account compromise attacks.
