What is a Secure Password?
A secure password has these characteristics: (1) At least 8 characters long (preferably 12+), (2) Includes uppercase, lowercase, numbers, and special characters, (3) Doesn't contain dictionary words or personal information, (4) Random character combination without obvious patterns. Passwords generated by this tool meet all these security criteria. The more important the account (banking, email, social media), the stronger your password should be.

- Use different passwords for different websites. If one account is compromised, all are at risk.
- Change your passwords regularly every 3 months.
- Use password management apps like LastPass, 1Password, or Bitwarden.
- Never include personal information like birthdate, name, phone number, or pet names.
- Don't share passwords, write them down, or rely only on browser autofill.
- Passwords generated here are created only in your browser and never stored on servers - absolutely safe.
