Protect your account with two-step authentication.

Two-step authentication adds extra security by making it harder for someone else to log in to your account, especially if they steal your password. After you enable two-step authentication, when someone attempts to log in to your account with your password, Firefox will also ask for an authentication code from your authentication application for proof that it’s really you. =How do I enable two-step authentication?= ==Step one== Before you get started, download one of the following authentication applications: *Authy 2-Factor Authentication **[https://authy.com/download/ Windows] **[https://authy.com/download/ macOS] **[https://snapcraft.io/authy Linux] **[https://play.google.com/store/apps/details?id=com.authy.authy Android] **[https://itunes.apple.com/us/app/authy/id494168017?mt=8 iOS] *Google Authenticator **[https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2 Android] **[https://itunes.apple.com/us/app/google-authenticator/id388497605?mt=8 iOS] *Duo Mobile **[https://play.google.com/store/apps/details?id=com.duosecurity.duomobile&hl=en Android] **[https://itunes.apple.com/us/app/duo-mobile/id422663827?mt=8 iOS] *FreeOTP **[https://play.google.com/store/apps/details?id=org.fedorahosted.freeotp Android] **[https://itunes.apple.com/us/app/freeotp-authenticator/id872559395?mt=8 iOS] *andOTP (Android only) **[https://play.google.com/store/apps/details?id=org.shadowice.flocke.andotp Google Play] **[https://github.com/andOTP/andOTP/releases GitHub] **[https://f-droid.org/en/packages/org.shadowice.flocke.andotp F-Droid] *KeepassXC **[https://keepassxc.org/download/#linux Linux] **[https://keepassxc.org/download/#mac macOS] **[https://keepassxc.org/download/#windows Windows] ==Step two== Now that one of the applications is installed, we can set up two-step authentication in Firefox: #Click on the menu button [[Image:menu button retina|width=25]] at the top right corner. #Click Firefox Accounts from the menu (it will show your email address if you're signed in). #Click {menu Manage Account}. The Firefox Accounts Settings page will open. #Under ''Security'', click the {button Add} button next to '''Two-step authentication'''. A QR code will display. #Open the authentication app of your choice. #Use the app to take a photo of the QR code, or click '''Can’t Scan Code''' to display a code to enter into the app. (If you are entering the code manually on Authy Mobile, search "Firefox 100" to get the latest logo) #Enter the code generated by the app into the Firefox Accounts Two-step authentication section and click '''Continue'''. #Download or print your backup authentication codes and keep them in a safe place in case you lose access to your authentication application. #Copy one of the backup authentication codes to confirm that you have saved them and click '''Continue'''. #Paste the code and click '''Finish'''. The setup of your two-step authentication is now complete!
