Hello everyone, in order to improve security, we will permanently enable the 2FA feature for all GitLab accounts starting in January 2025. We kindly ask you to enable 2FA on your GitLab account yourself as soon as possible before we proceed with the global activation (instructions: https://www.youtube.com/watch?v=YWeGgGLjhqk&t=142s). We rely on you not to wait for the global activation. Thank you for your cooperation. For any questions, please contact it-support@sib.swiss.
