OpenVPN is a popular protocol for creating a safe and secure virtual private network (VPN) connection.
It is a secure and fast way to connect to the internet from a remote location, like a public Wi-Fi.
In this article, I’ll show you how to use the Google Authenticator to set up and connect to an OpenVPN server.
What Is Openvpn?
OpenVPN has become the most popular open-source encrypted VPN software available. It is especially popular among privacy and security advocates.
OpenVPN is a network tool that allows two or more computers on the same network to send and receive encrypted data.
OpenVPN also supports remote access for devices that aren’t on the same local network.
OpenVPN uses open-source protocols like PPTP and OpenVPN, as well as proprietary protocols like IKEv2 and SSTP. It also uses the IPsec protocol, which is a proprietary protocol.
OpenVPN is free software, and the source code is available for anyone to view, modify, and distribute.
What Is Google Authenticator?
Google Authenticator, or Authenticator for short, is a mobile app created by the tech giant Google. It’s used to verify your identity when you log in into your email, social media, or other accounts using two-factor authentication (2FA).
2FA adds an extra layer of protection to your accounts by first requiring a password and then requiring you to use a “second factor” to verify your identity.
Your “second factor” can be anything from a code generated by a physical hardware device to an SMS code that is sent to your mobile phone.
You can then enter this code into the app to log in to GCP.
Benefits of Using Openvpn With Google Authenticator
The biggest benefit of using OpenVPN with Google Authenticator is that it makes OpenVPN more secure.
By default, OpenVPN uses passwords to authenticate users.
When a login attempt fails, the OpenVPN client closes and restarts. This protects against brute force attacks and other forms of password guessing. But it also makes it easier for attackers to gain unauthorized access to user accounts.
With OpenVPN’s password authentication, users only need to remember one password. But an attacker can guess it.
With OpenVPN and Google Authenticator, users need a second password. When OpenVPN receives a login attempt, it prompts the user for a password. If the user enters their Google Authenticator password, OpenVPN accepts the login. This protects against brute force attacks and other forms of password guessing.
How to Set Up Openvpn With Google Authenticator
OpenVPN is a widely used piece of software that provides encrypted access to the internet. It can create a secure and private VPN for devices, or act as a secure and private proxy.
Google Authenticator is a seemingly simple two-factor authentication app that requires the user to enter a six-digit code sent to their phone.
Setting up OpenVPN with Google Authenticator works similarly to setting up any other OpenVPN connection. In this case, however, instead of connecting to a server, the OpenVPN client connects to a Google Authenticator server.
Best Practices for Setup and Maintenance
While Google Authenticator and OpenVPN are relatively easy to set up, there are some best practices you can follow to make setup and operation as smooth as possible.
OpenVPN and Google Authenticator are both open-source projects. This means that the source code is available for all to see. This means you can see exactly what the software is doing behind the scenes.
This gives you insight into how the software works and how well it has been maintained.
Additionally, you can gain an idea of the security features that are present and how they protect users.
With OpenVPN, there are many options. The developers behind OpenVPN are constantly adding new features.
The developers behind Google Authenticator are more limited. Google Authenticator only offers two options: 2-Factor Authentication or 1-Factor Authentication.
The Future of Openvpn and Google Authenticator
Both OpenVPN and Google Authenticator seem like strong solutions. While no company is perfect, both seem to have positives. While Google Authenticator has support for many services, including email, Facebook, Twitter, etc., and uses your phone’s built-in features, OpenVPN’s features seem a bit more robust. It’s open source, and can support advanced security features. However, OpenVPN seems to rely on third-party apps to access these features, while Google Authenticator (and similar services) use features built into the phone.
Both seem to have many potential uses. There are plenty of different VPN providers. There are too many different VPN apps.
It seems many VPN apps have issues or bugs, and OpenVPN seems to have fewer. However, this is still a matter of opinion, and only time will tell which solution will win.
Regardless, both solutions seem to be good. If you’re using OpenVPN and Google Authenticator, consider giving other VPN providers a try (or VPNs without a VPN app, such as TunnelBear).
