How often should I change my passwords?

The latest NIST guidelines say don't change passwords on a schedule — only change them if you suspect a breach. Focus on making each password strong and unique instead.

Are passphrases better than random passwords?

Both can be equally secure if long enough. A 4-word passphrase has about the same entropy as a 12-character random password. Passphrases are easier to remember; random passwords are shorter.

The Password Length Rule

In 2026, the minimum safe password length is 12 characters. An 8-character password can be cracked in hours. A 12-character password takes months. A 16-character password takes centuries. For critical accounts, use a 20-character password or longer.

Different Passwords for Different Purposes

Use a strong password generator for your email and banking. Use a Wi-Fi password generator for your home network. Use an API key generator for development tokens. For your database, use a database password generator with maximum entropy.

PINs and Simple Passwords

For phone locks and ATMs, use at least a 6-digit PIN instead of a 4-digit PIN — it's 100x harder to guess. For systems that don't allow special characters, use an alphanumeric password or password without special characters.

The Master Password

Your password manager's master password is the most important password you'll ever create. Make it at least 20 characters, memorable but unique. A secure password with high entropy protects everything else.
