What makes a password strong?

Strong passwords are unique and random.

Humans aren't very good at coming up with passwords that are either of those things, let alone both. So we created the 1Password Strong Password Generator to create secure, memorable passwords for you. 81% of data breaches are caused by weak or reused passwords, so random, unique passwords are your best defense against online threats.

Why should my password be unique?

If you use the same password for both your email and your bank account login, an attacker only needs to steal one password to get access to both accounts, doubling your exposure. If you've used that same password for 14 different accounts, you're making the attacker's job very, very easy. You can protect yourself by using a generator to create unique passwords that are easy to remember.

Why should my password be random?

Random passwords are hard to guess and harder for computer programs to crack. If there's a discernible pattern, the odds of an attacker gaining access to your account go up exponentially. Random passwords might contain a jumble of unrelated characters, but combining unrelated words also works. That's how the 1Password Strong Password Generator creates passwords that are easy to remember but still cryptographically strong.

If it sounds hard to come up with a unique, random password each and every time you sign up for a new service, that's because it is. That's why we built the 1Password Strong Password Generator to generate strong passwords for you.

It's also quite hard to remember all those passwords when you need them. That's why we made 1Password. 1Password is an app that works on almost any device to generate secure passwords on the fly. When you need to log into a site, 1Password will fill in the login details for you. All you need to remember is one single Master Password – your one password – that unlocks all of the random, unique passwords the 1Password app has generated for you.

I need to generate a strong, memorable password. Any tips?

A password generator is the best way to generate passwords that are both secure and easy to remember. But if you find yourself without access to the Strong Password Generator, keep these tips in mind.

Never include personally identifiable information in your passwords – or any fields related to your login credentials for that matter. You might be surprised at how much of that information can be found online. Those three security questions that your bank requires for you to log in? Don't answer those. Instead, use the Strong Password Generator to generate random, unique answers to those questions. Save the answers in your 1Password Vault just like you would a regular password, and you're good to go.

Remember, randomness is a critical factor in password strength, and the best way to generate a truly random password is with a password generator. If you need a password that's both random and memorable, simply select “Memorable Password” in the password generator. Instead of string of random characters, you'll get four easy-to-remember words strung together.

If possible, try to make passwords passwords at least 16 characters in length. Length can make a password much stronger than adding non-letters to a password. A 12-character, letters-only password is just eight times harder to crack than a 12-character password with digits, for example. But a 16-character, letters-only password is eight million times harder to guess than a 12-character password.

Similarly, there's no need to include a specific combination of uppercase letters, lowercase letters, and symbols. Doing so doesn't necessarily make the password stronger. What's more important is that the words used are random. However, because some services have specific character requirements, the password generator includes options to accommodate those requirements – not because it makes a stronger password, but because it makes it easier for you to create a password that works.
