Can someone explain how a standalone app like Google Authenticator which doesnt need a signal can generate a code acceptable by the forum and identifiable to me? How does it know it's me holding the phone? Not rhetorical, I just dont know.
I use a combination of Macbook with Airmail email client, five email accounts on Google mail and Outlook mail, and two android phones with Aquamail email client. Once started on the 2FA path the complexity (even for this retired IT person) and the danger of being locked out somewhere along the line are too great to contemplate at this time. All my mail accounts have single password entry since all the problems with the interim solution before 2FA.
Even if I activated it for this forum, the guy I bought from has my home address data in his PM and I can't protect that from my end. He would need to 2FA too.
Not sure how GDRP protects me either. I can't ask you to delete his PMs.
I prefer to stay relatively anonymous and use false personal data in forum profiles where possible ie be street smart.
I will now review how I communicate with sellers for next time.
