Technical fault in online filing services (reference no. CS322957)
We are currently experiencing technical problems with the 2FA (2 Factor Authentication) with our external SMS provider Twilio, first identified on 24.11.2025, at 13:30 h.
This is affecting the login to OLF, MyEPO, CFP and BDDS.
If you are affected please use another 2FA method, which can easily be setup.
If you haven't set up another authentication method and you have an urgent deadline, please contact our support team through our "contact us" link.

Our technicians are working to fix them as soon as possible.
We apologise for any inconvenience.
