Your LuxTrust certificate will not be affected by the closure of your ING account.
This certificate is issued by ING in its capacity as Registration Authority on behalf of LuxTrust and is specific to you: you can use it to identify yourself at other banks and to certain authorities.
Your certificate will remain active until its expiry date (please refer to the LuxTrust website for further information).
In some cases, it is possible that the LuxTrust certificate you were using at ING cannot be used at your new bank. In this case, your new bank will help you to create a new LuxTrust certificate.
However, please note that at the end of this year, the (physical) token will no longer exist (following a decision by LuxTrust, following a press release to this effect). We therefore advise you to download and use LuxTrust Mobile before the end of this year.
