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.
