What Is a Password Generator?

Password Strength Guidelines

How long should your password be?

• Email: 16+ characters (your email is the key to all other accounts)
• Banking: 16+ characters (protects your money)
• Social media: 12-16 characters
• Shopping: 12-16 characters
• Streaming services: 12 characters
• Throwaway accounts: 8-12 characters

Rule of thumb: Longer is always better. A 16-character password is exponentially harder to crack than a 12-character one.

Security Best Practices

• Use unique passwords: Never reuse the same password across multiple accounts.
• Use a password manager: Store generated passwords in Bitwarden, 1Password, or LastPass.
• Enable two-factor authentication: Add a second layer of security to important accounts.
• Check for breaches: Use Have I Been Pwned to see if your email has been compromised.
• Update regularly: Change passwords for important accounts every 3-6 months.
