Blitz Authenticator

Blitz Authenticator is the companion app for B5 accounts. It links your B5 account to your phone, so your phone becomes a trusted, secure key for your account.

HOW IT WORKS
• Sign in to B5 on the web and open My Profile.
• Choose to link a phone. B5 shows a QR code and a 32-character code.
• In Blitz Authenticator, scan the QR code or type the code.
• Confirm with your face, fingerprint or screen lock, then confirm the matching 4-digit code in your browser.

BUILT FOR SECURITY
• Your security keys are created inside your phone's secure hardware (Secure Enclave or Android Keystore) and never leave it.
• The app only connects to approved B5 servers, always over an encrypted connection.
• Every request to B5 is signed by your phone, so B5 knows it really comes from your linked device.
• The app checks that your phone has a screen lock and follows your organization's security rules.
• Optional app lock keeps your linked accounts private.

YOU STAY IN CONTROL
• See which B5 accounts are linked to this phone.
• Remove an account at any time. The phone is removed from your B5 account too.
• If your phone is removed from B5 My Profile, the app shows the account as unavailable.

MADE FOR YOUR LANGUAGE
Available in English, Arabic, German, Spanish, French and Turkish, with full right-to-left support for Arabic.
