BlokSec 4.0 is here -- completely rebuilt with location-aware login approval, encrypted QR backups, dark mode, and a smoother experience on every screen. BlokSec replaces passwords with secure, one-tap authentication. When you sign in to an application protected by BlokSec, you simply scan a QR code and approve the request - no passwords to type, forget, or have stolen. Your organization's administrator invites you to BlokSec. Once you accept the invitation, the app automatically discovers all the applications you have access to. No separate setup for each app. HOW IT WORKS 1. Open the login page for any BlokSec-protected application 2. Scan the QR code with BlokSec 3. Review the sign-in request and tap Approve 4. You're in. That's it. LOCATION-AWARE APPROVAL Every sign-in request shows you where the login is being attempted on a map, so you can verify it's coming from where you expect. If something looks off, deny the request with a single tap. PUSH NOTIFICATIONS When a sign-in request comes in, you'll get a push notification. Tap it to go straight to the approval screen -- no need to open the app and scan a QR code every time. ENCRYPTED BACKUP & RESTORE Back up all your accounts as an encrypted QR code, protected by a passphrase that only you know. Restore on a new device in under a minute by scanning the backup code. SECURITY YOU CAN TRUST * PIN and Face ID/Touch ID protect every sign-in approval * Private keys are derived from a cryptographic wallet and never leave your device * All communication with BlokSec servers is signed with your device's unique key * No passwords are stored or transmitted -- ever BUILT FOR YOUR ORGANIZATION BlokSec works with the applications your organization already uses, including Microsoft 365, Google Workspace, Salesforce, and any app that supports OIDC, SAML, or WS-Federation. This app requires an invitation from a BlokSec-enabled organization. Contact your IT administrator to get started.
