I seem to have locked down FB and Twitter, (those were hacked too, and Microsoft, Steam and allegedly ticketmaster) but man...Instagram is constantly being hacked into even though I have 2-step authentication ON.

So every time a password changes, I get a code to my phone/SMS that only I should have in order to allow the password change.

By the time I notice I've gotten a code I didn't ask for, someone is already in my account and changing my password.

I can get back in, but this is happening several times per day!

How are they doing this? How are they getting my special code from SMS? Is someone duping my phone, and how did they do THAT???

Or is something else happening?

I don't have time for this, but I need my IG up it's where I showcase my photography and arrange shoots with models.

IG is silent on the issue.
