I had Zoho set up on the lowest tier for a side-hustle project years ago. It did it's job smoothly and without much intrusion. Then the project ended and I forgot about the Zoho account, changed phone numbers, lost the 2fa keys - all of it. Totally my fault. Their support quickly and competently handheld me through the shutdown process. I can't imagine the nightmare Google would've forced me through to shut down a pointless 3$/month charge had I made the same mistake with them.
