Password Security Best Practices in 2026

Enable Two-Factor Authentication

Even the strongest password can be compromised. Two-factor authentication (2FA) adds a second layer of security — something you have (a phone) in addition to something you know (a password). Use authenticator apps instead of SMS when possible.

Use a Password Manager

Password managers are no longer optional for security-conscious users. They generate, store, and auto-fill unique passwords for every account. Combined with a strong password generator, you never need to create or remember passwords manually.

Passkeys Are the Future

Passkeys (FIDO2/WebAuthn) replace passwords entirely with cryptographic key pairs. Your device holds a private key; the service holds the public key. Authentication happens locally with biometrics or a PIN. Passkeys eliminate phishing, credential stuffing, and password reuse risks entirely.

Stop Rotating Passwords Unnecessarily

NIST now advises against mandatory periodic password changes without evidence of compromise. Frequent forced rotation leads to weaker passwords as users make minor, predictable modifications. Only change passwords when there is reason to believe they have been compromised.
