How to use SSO with Proton VPN for Business

Our Proton VPN for Business plans support single sign-on (SSO) as an early access (beta) feature. In this article, we look at what SSO is, how to set up and manage it for your business or organization, and how staff members can use it.

What is SSO?

Single sign-on technology allows you to access multiple applications and websites with a single username and password. The primary goal of SSO is to simplify the user experience by eliminating the need to remember and enter different usernames and passwords for each application you use to access your company’s resources and services. 

What is SSO?

In a typical SSO scenario, once you log in to one of the connected applications, you’re automatically granted access to other applications without needing to log in again. This is not only convenient, but it enhances security by encouraging the use of stronger, unique passwords. It also reduces the likelihood of people resorting to insecure practices, such as using the same password across multiple services.

SSO is currently used mainly in business contexts, providing a convenient yet secure way for staff to access multiple SaaS applications. Network administrators can also  use it to provide segmented access to company resources (that is, to restrict access to resources based on, for example, a user’s role or seniority within your organization). 

SSO login credentials are typically managed by an identity provider (IdP) who verifies your credentials and, upon successful authentication, generates a token that your browser will use to automatically sign you in to websites and other services. Popular identity providers include Okta.

Proton VPN currently supports SSO using Security Assertion Markup Language (SAML) 2.0, an XML-based open standard for transferring data that verifies your identity between an identity provider and SaaS applications. 

How to set up SSO for Proton VPN

Before you start, you’ll need the following: 

  • An account with an identity provider such as Okta
  • Once you have an account with an identity provider, you’ll need to configure it for Proton VPN. Your identity provider should then be able to provide the information required to configure SAML on your Proton VPN for Business account.

How to configure SAML SSO on your Proton VPN for Business account

1. Log in to your Proton VPN for Business administrator account at account.protonvpn.com and go to Single sign-onSAML authenticationConfigure SAML

2. Add the domain name provided by your identity provider and click Add domain

3. Verify the domain for your identity provider. To do this, log in to your domain provider’s web portal and enter the DNS TXT record displayed on this screen. 

Click Continue once you’ve done this. 

Verify domain

4. Import the SAML metadata for Proton VPN from your identity provider. You can import this data via URL, XML file, or by manually filling out Text fields. Select your preferred method (which may be determined by your IdP) and input or upload the requested data.

Click Continue when you’re done. 

Enter SAML metadata

5. Provide the endpoints shown to your identity provider. If your IdP asks for an Assertion Consumer Service (ACS) URL and Issuer ID, simply copy and paste the information from this screen into your identity provider fields. 

Once you’ve done this, click Done

SSO should now be configured on your Proton VPN for Business account. Click See details for an overview of your SSO settings.
