Two Factor Authentication Issue
The last time I logged in via webmail I was asked to set up Two Factor Authentication. I did all the confirmations. However, MAC Mail would no longer allow me to connect to Zoho once this was done, for sending or receiving emails. So I had to disable 2FA. Not sure if this is a security feature or something, but just in case anyone else has this happen to them, I figured it was worth posting. This was very frustrating.
