I am in a similar situation. Started HA both at house and at work a year ago. Finally got house going - back to work and on starting it is asking for Two Factor Authentication - which I can not remember setting up. I have checked my mobile and spam bins of my email accounts and not received any 2FA codes there. So I think that I need to remove this feature.
I am following through @danwize post and am stuck at step 4. I don’t know how to move to the “hidden .storage folder” as instructed
I then need instructioins please how to do this and how to do step 5. rename the totp file with “mv auth_module.totp auth_mudule.totp.tmp”
currently sitting as below
