Use a tested browser
To open the MitID app, you should use a browser that is installed on your mobile or tablet, such as Safari or Google Chrome. If you have followed a link via an app (e.g. Facebook or LinkedIn), you may be in an "in app browser" from which MitID cannot be used.
These browsers are tested and work with the MitID app
Avoid private or incognito mode
Make sure your browser is not in private or incognito mode. Authentication must be done in an open browser.
You can check your browser's mode under settings in the browser.
Contact MitID Support
If problems persist, you can contact MitID Support for further assistance.
