You cannot log in between 6 a.m. and 7 a.m.
How does logging in work?
In order to log in you will need a DigiD with SMS verification. If you have a DigiD without SMS verification, please request SMS verification. You will receive a letter with an activation code within 5 days.
Logging in from abroad
With a DigiD you can also log in to Mijn DUO from abroad, although you may have to arrange a few things first.
