If you have been logged into a self-service, Digital Post,, or other public websites with MitID at a computer that others have access to, remember to log out properly before you leave the computer. This applies, for example, at the library or if several of you share a computer at home. You do this in the following way:

  • Click the ‘Log out’ button on the website and then close all windows in your browser (that is all open internet windows).

If you do not log out and close all internet windows, you run the risk of another person sitting at the same computer gaining access to your personal information.

Why does this problem occur?

Internet browsers such as Internet Explorer, Firefox, Safari and Chrome all try to make it as easy as possible for you to be online. Therefore, the programmes ‘remember’ that you are logged in, even if you close one tab or window.

In the latest versions of Chrome and Firefox, it is even possible to set the browser so that you are still logged in even if all internet windows are completely closed. If you reopen the browser, you are still logged in unless you have actively selected ‘Log out’ on the website.

You may find that you are logged in to Digital Post,, or other public websites when you open a browser again. This can happen if you forgot to log out before closing the previous browser window.

Therefore, always make sure to click the 'Log out' button on the website when you have completed your errand.
