GO2FA - Secure every charging session with two-factor authentication

GO2FA is Global Charging’s patent-pending OCPI 2FA solution. It adds a robust second-factor authentication layer to every EV charging session - protecting drivers, eMSPs, and CPOs from fraud and unauthorised use, without adding friction to the charging experience.

What is GO2FA?

A second layer of security built into the OCPI protocol

GO2FA (Global Charging Two-Factor Authentication) is a patent-pending security layer that wraps the standard OCPI authentication flow with a real-time second-factor verification step.

Before a charging session is allowed to proceed, the user must confirm their identity through an external channel - making it virtually impossible for unauthorised parties to start a session using a stolen RFID card or token.

Supported authentication methods

RFID card - physical card tap at the charging station
App / Web app - remote start via mobile or web
Autocharge - automatic vehicle recognition
Plug & Charge Coming soon

2FA

layers of verification before any session starts

second-factor delivery channels supported

decision latency - session initiation is non-blocking

OCPI

native - no protocol changes required

How It Works

Two flows. One standard. Zero compromise.

GO2FA adapts to both real-time and non-real-time authorization networks, ensuring maximum compatibility across all EV charging ecosystems.

Standard Flow

With Real-Time Authorization

User Authentication
User presents credentials at the charging station. Identity is established and the secure authentication chain is triggered.

GO2FA 2nd-Factor Challenge
GO2FA delivers a verification request via email, SMS, WhatsApp, biometrics, or AI assistant. Session is held pending.

Validation Decision
Validated → session starts with uninterrupted power. Failed or timed out → session is immediately terminated.

eMSP / CPO Coordination
Systems coordinate to manage the session, track usage, and handle billing with full security assurance.

Mobi.e Flow

Without Real-Time Authorization

Mobi.e Token Validation
Mobi.e acts as the trusted gatekeeper, verifying the user’s token against a whitelist without real-time eMSP authentication.

Session Starts
Once the token is validated, the charging session begins immediately. The plug connects and power flows in milliseconds.

GO2FA Parallel Validation
GO2FA validates the session in parallel. Success → session continues. Failure → session is terminated to prevent unauthorised use.

Why Mobi.e? Mobi.e is Portugal’s national EV charging network operator. It uses a whitelist-based token system without real-time eMSP callbacks - a common pattern in national roaming networks. GO2FA adds the missing security layer.

Second-Factor Channels

Reach users on any channel

GO2FA delivers the second-factor challenge through multiple external channels, ensuring compatibility with any user preference or device.

Key Benefits

Security and convenience, not a trade-off

GO2FA ensures secure, fraud-free EV charging sessions by combining robust security protocols with an effortless user experience.

Trust

Multi-layer authentication builds confidence in the charging ecosystem for all stakeholders - drivers, eMSPs, and CPOs alike.

Safety

Advanced fraud detection protects users, operators, and service providers from unauthorised session starts and financial threats.

Convenience

Seamless validation happens in seconds, ensuring a smooth and uninterrupted charging experience for the end user.

OCPI Native

Built on top of the OCPI protocol, GO2FA integrates natively with existing eMSP and CPO infrastructure without requiring protocol changes.
