Password Security Tips

Length matters. Use passwords with at least 12-16 characters for better security.
Mix character types. Combine uppercase, lowercase, numbers, and symbols.
Use unique passwords. Never reuse passwords across different sites or services.
Consider a password manager. Tools like 1Password, LastPass, or Bitwarden can help manage unique passwords.
Enable two-factor authentication (2FA). Add an extra layer of security beyond passwords.
Change passwords regularly. Update critical accounts every 90 days.
Avoid personal information. Don't use birthdays, names, or other easily guessable data.

Frequently Asked Questions

What makes a password strong?
Strong passwords are long (12+ characters), use a mix of character types, avoid dictionary words, and are unique for each service. Our generator creates passwords that meet these criteria automatically.
Are my passwords stored on your servers?
No. All password generation happens locally in your browser. Your passwords are never transmitted to or stored on our servers, ensuring maximum privacy and security.
How do I remember all these complex passwords?
We recommend using a password manager like 1Password, LastPass, or Bitwarden. These tools securely store all your passwords, so you only need to remember one master password.
Why should I exclude similar characters?
Excluding similar characters (like 1, l, I) makes passwords easier to read and type correctly, which is helpful when you need to manually enter them. This option is particularly useful for passwords you might need to type from printed materials.
How often should I change my passwords?
Security experts now recommend changing passwords only when there's a reason to believe they've been compromised. However, for critical accounts (banking, email), changing every 90 days is still good practice.
