KNHB Blocks AllUnited Login After Security Incident

If you log in to MijnHockey with your AllUnited details, the KNHB has a message for you. Use another way in for now.

The Dutch federation has temporarily blocked the link between AllUnited and MijnHockey, its member platform, after a security incident at AllUnited. AllUnited has confirmed the login details involved are being deleted, but the KNHB moved first anyway, blocking the connection as a precaution while it checks there’s no risk to its own members.

It’s a short-term fix, not a shutdown. The KNHB said the link would be switched back on later the same day, Wednesday, with an update on its own news page. In the meantime, anyone who normally signs in through AllUnited can log in with the email address on their KNHB account and the password they set in MijnHockey, or through a one-off magic link sent by email.

There’s one more thing the KNHB is asking people to do. If your KNHB password was the same as your AllUnited one, change it. That’s the practical bit, and it’s the one that matters most.

The incident sits with AllUnited, not the KNHB. The federation says it doesn’t use AllUnited software itself, but the two systems exchange data through an API, and that exchange has been blocked too. No MijnHockey user data has been put at risk, according to the KNHB.

Dutch club hockey runs on MijnHockey for memberships, teams and fixtures, so a login scare lands with a lot of people at once. The fix is simple enough, though. Log in the other way, change the password if it matched, and check the KNHB page for the all-clear.
