How to Generate a Strong Password That Is Hard to Guess
Create stronger passwords with practical length, uniqueness, and password-manager advice. Learn what makes a password secure and easy to manage.
A strong password is long, unique, and difficult for another person or program to guess. The most important rule is to use a different password for every account.
What makes a password strong?
Length is one of the biggest contributors to password strength. Aim for at least 14 characters when a service allows it. A randomly generated password with uppercase and lowercase letters, numbers, and symbols is a strong choice.
An alternative is a long passphrase made from several unrelated words. It can be easier to type while still being difficult to guess when the words are random.
Generate passwords instead of inventing them
People tend to reuse patterns, names, dates, and familiar substitutions. Attackers know these patterns. A password generator creates unpredictable combinations that are much harder to crack.

Use a password manager
The safest way to manage unique passwords is a reputable password manager. It creates, stores, and fills long passwords, so you only need to remember the password-manager passphrase.
Turn on two-factor authentication
Two-factor authentication (2FA) adds another check after your password. Enable it for email, banking, social accounts, and any service with sensitive information. An authenticator app or security key is generally stronger than an SMS code.
Never share your password, and change it immediately if you believe an account has been exposed.
