Password Best Practices

Small changes. Big protection.

Use a Passphrase

4+ random words are easier to remember and harder to crack than short complex passwords.

Enable 2FA

Add a second layer of security. Even strong passwords benefit from two-factor authentication.

Never Reuse

One breach shouldn't open every account you own. Use unique passwords for each service.

Use a Manager

Let a password manager create and store unique passwords for all your accounts.
