thumb|right|Gmail password strength meter 'Password strength' is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to correctly guess it. The strength of a password is a function of length, complexity, and randomness. However, other attacks on passwords can succeed without a brute search of every possible password.

- thumb|right|Gmail password strength meter 'Password strength' is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to correctly guess it. The strength of a password is a function of length, complexity, and randomness. However, other attacks on passwords can succeed without a brute search of every possible password. For instance, knowledge about a user may suggest possible passwords (such as pet names, children's names, etc). Hence estimates of password strength must also take into account resistance to other attacks as well. Using strong passwords lowers overall risk of a security breach, but strong passwords do not replace the need for other effective security controls. The effectiveness of a password of a given strength is strongly determined by the design and implementation of the authentication system software, particularly how frequently password guesses can be tested by an attacker and how securely information on user passwords is stored and transmitted. Risks are also posed by several means of breaching computer security which are unrelated to password strength. Such means include wiretapping, phishing, keystroke logging, social engineering, dumpster diving, side-channel attacks, and software vulnerabilities.
- 密码强度指一个密码被非认证的用户或计算机破译的难度。 密码强度通常用「弱」或「强」来形容。「弱」和「强」是相对的，不同的密码系统对于密码强度有不同的要求。密码的破译与系统允许客户尝试不同密码的次数、是否熟悉密码主人等因素相关。然而，即使再强的密码也有可能被偷取、破译或泄漏。

- Bruce Schneier 2005
- Simply, people can no longer remember passwords good enough to reliably defend against dictionary attacks, and are much more secure if they choose a password too complicated to remember and then write it down. We're all good at securing small pieces of paper. I recommend that people write their passwords down on a small piece of paper, and keep it with their other valuable small pieces of paper: in their wallet.
