What is two-factor authentication?


Two-factor authentication, or 2FA, is a subset of multi-factor authentication and adds an extra layer of security by requiring an additional login step. After entering a password to log in, you’ll be asked to provide a security key which can come in the form of a numerical code, barcode, QR code, or other piece of information. Only by providing the right information will you be granted access to the account.

If a password is stolen or leaked online by a hacker and someone else is trying to log in to your account, they won’t be able to without the 2-factor authentication!

How does two-factor authentication work?

The first half of the authentication process involves you entering your account login and password.

Passcode is sent to Android device

Your chosen authenticator app will generate a unique verification code on-screen as a QR code to scan or numerical code via text message. These tokens will vary across different 2FA apps.

Verify the token

Your mobile device will then prompt you to confirm the unique token. This can be done by scanning the QR code or entering the numerical string sent to your mobile device.

Why use two-factor authentication?

The right two-factor authentication app makes browsing with Android more secure, without slowing down your day.

Add extra protection

Worried about phishing attacks or malware? Two-factor authentication keeps hackers locked out.


Simplify online security

Combining 2-step verification with a password manager eliminates the need to remember your passwords!


It's free!

Many popular two-factor authentication options, including LastPass Authenticator, can be downloaded for free.

« 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. »

« 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. »
