Honestly, we seriously dropped the ball trying something new. It was a mistake on my part and a bad decision looking back. I posted about it on our blog here https://www.namecheap.com/blog/true-totp-2fa-and-u2f-are-com...
This is probably the worst place to air a grievance like this, but it seemed like my frustrations had fallen on deaf ears. I haven't bought a domain from namecheap since.
Let's Encrypt. Ever going to roll it out?
I plan to switch away from Namecheap soon unless it's implemented, it's really disappointing to me.
You guys are hosting my email and I couldn't be happier.
