GateCore Authenticator

CODE AND SYSTEMS LTD

About this app

GateCore Authenticator adds a second layer of security to your work accounts. Instead of relying on a password alone, every sign-in is confirmed from your own phone.

Built by Code and Systems Ltd for businesses that need strong authentication without the complexity.

TIME-BASED CODES
Generate 6-digit one-time passwords that refresh every 30 seconds. Add an account by scanning a QR code and your codes are ready straight away. Tap any account to see the full code and copy it in a single move.

PUSH SIGN-IN APPROVAL
When someone signs in to your account, a request appears on your phone showing where it came from. Confirm it by tapping the matching number on screen. That simple check stops accidental approvals and blocks push-fatigue attacks. If it was not you, deny it instantly.

ENCRYPTED CLOUD BACKUP
Back up your accounts so a lost or replaced phone does not lock you out. Sync is encrypted and entirely optional. You decide when it runs.

BIOMETRIC PROTECTION
Lock the app behind your fingerprint or face so your codes stay private even when your phone is unlocked.

WORKS WITH YOUR WORKPLACE
Supports standard TOTP accounts as well as Microsoft and Azure sign-ins, so one app covers the services your team already uses.

BUILT FOR TEAMS
Designed to sit alongside GateCore Endpoint Protection, the security platform used by UK businesses to manage devices, enforce multi-factor authentication and monitor endpoints.

PRIVACY
We collect only what the app needs to work: your email address, your user ID and a device identifier. No advertising, no tracking, no analytics. Your one-time password secrets are used to generate codes and nothing else.
