Passwords are a major defense against hackers, and developing good password practices will help keep your sensitive personal information and identity more secure.
Tips for Developing Better Passwords
- Passwords should have at least 10 characters, include uppercase and lowercase letters, numbers, and symbols.
- Avoid common words; some hackers use programs that try every word in the dictionary.
- Never use personal information (your name, children’s names, dates of birth, etc.) that someone might already know or easily obtain.
- If you believe your system has been compromised, change your passwords immediately.
- Use different passwords (or at least a variety of passwords) for each online account you access.
- If you must write down your passwords, keep them in a secure location away from your computer. Under no circumstances should you store them in a document on your computer!
