Microsoft – Create strong passwords
“A strong password is an important protection to help you have safer online transactions. Here are some steps to create a strong password. Consider using some or all to help protect yourself online:
- Length. Make your passwords at least eight (8) long.
- Complexity. Include a combination of at least three (3) upper and/or lowercase letters, punctuation, symbols, and numerals. The more variety of characters in your password, the better.
- Variation. Change your passwords often. Set an automatic reminder to update passwords on your email, banking, and credit card websites every three months.
- Variety. Don’t use the same password for everything. Cyber criminals can steal passwords from websites that have poor security, and then use those same passwords to target more secure environments, such as banking websites.”
