Strong Password Tips

  • Use at least 12-16 characters
  • Mix uppercase, lowercase, numbers, and symbols
  • Avoid personal information (names, birthdays)
  • Don't use common words or patterns
  • Consider using a passphrase (e.g., "Coffee-Mountain-Bicycle-42!")
  • Use unique passwords for each account

Your password is analyzed locally and never sent anywhere.
