How can you protect your passwords?

Phishing, stolen credentials, and human error challenge your password security. Take action and improve your defense against them.

  • With the LastPass built-in password generator you don’t need to fuss with thinking of new passwords. LastPass will generate a unique password for each account you create.
  • Make sure your passwords are at least 12 characters long and contain letters, numbers, and special characters.
  • Don’t use any personally identifiable information in your passwords.
  • Avoid password reuse with the security dashboard, which alerts you to take proactive action when you’ve reused a password or created a weak one.
  • When you create a password on your own, use random characters, but don't follow easy-to-recognize patterns – e.g. “qwert” or “12345.”
  • Never share your passwords via email or text message. Share your sensitive information with friends and family through LastPass’ secure password sharing.
  • Avoid using similar passwords that change only a single word or character.
  • Update passwords after every three months.
  • Use a password manager like LastPass to save your passwords, it keeps your information protected from attacks or snooping.

Frequently asked questions

How does the password generator work?

The LastPass password generator creates random passwords based on parameters set by you. Parameters include password length, whether the password should be easy to say or read, and whether the password should have uppercase letters, lowercase letters, numbers, and symbols.

The password generated, based on the user's parameters, is then checked against the zxcvbn library – a standard in evaluating password security – to see how strong the password you generate is.

Can a strong password be hacked?

While a strong password can be technically hacked, it would take an imperceivable amount of time to do so. A recent report found that a 12-character password made only of numbers would take just 25 seconds to hack. Compare that to a 12-character password made up of numbers, uppercase and lowercase letters, and symbols, and the amount of time it would take to hack increases to 34,000 years. So a strong password won’t be hackable in your lifetime. Read more in the infographic.

Can I use the password generator to create a user name?

You should use the LastPass username generator tool to create a secure username. It ensures you get a random, unique username that exists only of uppercase and lowercase letters.

How do you manage your passwords with a password manager?

Managing passwords in the LastPass password manager is simple. Every time you save a password to your LastPass account, it is stored inside of your password vault – an encrypted space that only you can see and access. You can manage your passwords by simply accessing your password vault and searching for the credential you need. And with the LastPass browser extension and app, you can seamlessly save and autofill passwords while on your computer, smartphone, or tablet.

Is LastPass password generator safe?

Yes. The LastPass password generator creates random, secure passwords based on the parameters defined by you. Any password generated is tested against the industry-standard zxcvbn library to determine how strong the password you generate is.

Lastly, once you save the password you generated to your password vault, it is automatically encrypted and stored so only you can access it and see it.

Is the functionality different in the online generator and in the LastPass app?

No. The browser and in-app password generator function the same. The only difference is that the in-app generator will also autofill and save the created password for you. Whereas with the online generator, you must copy your password and paste it into the necessary form field.

« J’apprécie le fait que LastPass soit facile à utiliser et intuitif. Il s’intègre bien avec tous les sites web et me permet de chiffrer l’accès à tous mes comptes personnels et professionnels. Il me permet aussi de gérer et partager mes dossiers, et ne devoir mémoriser qu’un seul mot de passe maître pour tout sécuriser est un soulagement. »

Kenny Kolijn

Coach en entreprise indépendant

« J’utilise LastPass à titre personnel et professionnel. Il me permet de stocker et de partager en toute sécurité mes mots de passe avec mes proches et mes collègues dans des environnements séparés, et il me génère volontiers des mots de passe aléatoires sûrs, ce qui m’évite de les réutiliser. »

« Si vous devez gérer les informations de personnes tierces, comme c’est le cas de ma société, LastPass est un must. Nous l’utilisons pour classer les identifiants client sensibles, et il ne nous a jamais déçus. Son niveau de sécurité nous donne la souplesse nécessaire lorsqu’un fournisseur ou un membre de l’équipe a besoin d’un accès, mais que nous ne voulons pas lui fournir le mot de passe. »
