Multi-factor authentication in CSC’s Services for Research

CSC is expanding the use of multi-factor authentication in our services, and since June 11th 2025, CSC requires all users to use MFA when accessing MyCSC portal. Logging in to Puhti and Mahti web interfaces also requires MFA since April 22nd 2025.

In today’s digital world, protecting our online accounts is more important than ever. One effective way to enhance security is through Multi-Factor Authentication (MFA, in Finnish: monivaiheinen tunnistautuminen).

But what exactly is MFA, and why do we require it for CSC Services for Research?

What is MFA and why is it important?

MFA is a security process that requires users to provide two or more verification factors to gain access to an online account. This method adds an extra layer of protection beyond just a password.

The primary motivation behind MFA is to enhance security. MFA significantly enhances security by protecting against password theft, reducing the impact of phishing attacks, and preventing unauthorized access. Even if a password is compromised, the additional verification factor makes it much harder for attackers to gain access to accounts.

Common MFA methods include, for example:

  • SMS authentication: Users receive a one-time code on their mobile phone to enter along with their password.
  • Authenticator apps: Apps like Google Authenticator or Microsoft Authenticator generate time-based codes for login.

How activate MFA

We encourage all our users to activate multi-factor authentication as soon as possible to ensure uninterrupted access to services.

Users logging in with Haka credentials: Your home organization may already offer multi-factor authentication during the Haka login process (Haka MFA). If Haka MFA is not enabled in your organization, activate CSC multi-factor authentication (CSC MFA). MFA Instructions for users logging in with Haka credentials in Docs CSC.

Users logging in with Virtu credentials, CSC login or Lifescience login: Activate CSC’s multi-factor authentication (CSC MFA) in MyCSC. Instructions in Docs CSC.
