Secure access to your systems

Add a second layer of security to your login process and protect access to VPN, servers and internal systems — without changing your existing authentication flow.

Stronger access security with 2FA

Two-factor authentication adds a second layer of security by requiring users to verify their identity beyond just a password. It combines something you know — like a password — with something you have, such as your phone. Simple2FA helps prevent unauthorized access, even if credentials are compromised, keeping your systems and users secure.

Protection against attacks

Reduce the risk of phishing, credential theft, and unauthorized access by requiring an additional verification step for every login attempt, protecting your systems even if passwords are compromised.

Built for real use cases

Secure access to VPN, servers, and internal applications with a solution designed for everyday authentication scenarios that works seamlessly across your existing infrastructure.

Simple to deploy and use

Roll out MFA quickly with minimal setup and no disruption, integrating into your current authentication flow without requiring major changes.

How it works

  1. User signs in to VPN, server or application
  2. Simple2FA requests a second factor
  3. Access is approved or denied
No changes to your existing authentication process

Full control over access

Access monitoring

Track all auth attempts and maintain full visibility over user activity. See who is accessing your systems, from where, and with what result. All events are collected in one place, making it easy to review access history, detect anomalies, and investigate incidents.

Access control & policies

Apply policies based on users, groups, or resources, allow exceptions for trusted environments, and reduce friction with session caching. All rules are managed centrally and enforced across connected systems.

Authentication methods

Provide secure and convenient ways to confirm access with multiple second-factor options. Use push notifications for fast approval, TOTP codes for offline scenarios, or Telegram-based verification. Combine methods depending on user roles and environments.

Simple2FA mobile app

Confirm login attempts instantly with push notifications or generate one-time codes when needed. The Simple2FA mobile app provides a simple and reliable way to approve access from your phone.
