To make logging in easier, we switched to logging in via SMS. Enter your mobile number including country code. So e.g. 0031 6 1234 5678. After requesting the code via 'Get SMS code' you will receive an SMS with a 4-digit code. Fill this in in the four fields. If you do not receive an SMS within 30 seconds, your mobile number has not been processed correctly on our side. Then use the link 'No sms code received?'. Enter your name and mobile number in the bottom box, we will process this data.
