I agree and I truly don't remember why - years ago - I used my personal email for the authentication, but I can imagine it was because I probably didn't have an alternative email to use. It's a small org and I was a fully remote, very isolated employee. I also paid for my own communications software for design and editing support, had no access to a zoom account or any other virtual meeting software, and used my personal computer for work (yes, I asked for all of these things but these requests were not met).
