What Makes a Strong Password?
A strong password should be at least 12 characters long.
The best passwords are random and unique for each account.
Tips for Creating Strong Passwords
- Use a passphrase: combine 4-5 random words
- Add numbers and symbols between words
- Never use personal information (birthdays, pet names)
- Use a different password for each service
- Enable two-factor authentication whenever possible
