If you suspect that your account is compromised you have the option to block the user (example in case of lost of login details, password, or other security features) before password changing.
In this case also your Bilderlings cards will be blocked and card data will not be available.
You can block the user on the web:
Go to Settings
Select Security
Go to Temporarily block user and press "Block user"
After successfully blocking a user, you will receive a notification.
You can unblock the user by contacting your manager.
