2FA is already enabled if you try and make any changes on your account.
You also have a security word set for any online or telephone enquiries to customer services.
This can be changed under your details in your MyO2.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
