I created the account when instagram first came out, never used it, and totally forgot about it. I got stuck in a strange position where I had to login from a device I had previously logged in from, but because it's been over a decade, I no longer have any of the devices I might have used to create/access the account.

I still have access to both the email and phone number used for the account, but that was not good enough.

How hilariously incompetent. I filed a CCPA complaint.
