It is essential to reduce all barriers to entry so that technical reasons can no longer be used as an excuse. Have you thought about:
Installing the link to the platform on the company intranet or on the collaborative portal.
Saving the platform access link in the favorites of all computers.
Proposing the platform access icon as a desktop shortcut on each workstation.
Enabling SSO (Single Sign-On) to allow direct authentication without the need to enter your password (Enterprise feature).
Synchronizing with the company directory to provide pre-filled profiles, which will accelerate onboarding to the platform (Enterprise feature).
Checking that each user is using an up-to-date browser (this may require updates on all workstations).
Setting Elium as the home page that opens when the browser starts each morning.
