What Makes a Secure Password?
Password Strength
Password strength is a measure of how effective a password is against being guessed or against brute-force attacks. Although it varies, usually, password strength is an estimate of how many trials would be required on average for someone to successfully guess the password. This is affected by the length, complexity, and unpredictability of the password.
For example, if a password involves a person’s name, birthday, or other personal information that typically would not be very difficult to find out, the password would likely make for a weak password.
Password Entropy
Password entropy is a measurement of password unpredictability. It’s measured in bits, and the higher the entropy, the more difficult it will be for the password to be guessed.
In the context of a brute force search (where every possibility is tested), a password entropy of 100 bits would require 2100 attempts for all possibilities to be exhausted. On average, about half of these possibilities would need to be exhausted before the correct one is found.
How to Protect Your Password
- Don’t share your password with others
- Use unique passwords for different websites and accounts
- Change your passwords periodically
- Never save passwords on public devices
- Consider using two-factor authentication when available
- Avoid entering passwords on unsecured networks
