I recently went looking for a registrar and one of the must-haves was U2F. Only Amazon and Google had it. Didn't know that Gandi has it as well. Good to know!
PS: I was disappointed that Cloudflare still doesn't have a U2F support yet they are a part of critical infrastructure for much of the web. We ended up not using them because of that.
I've had good luck with Gandi in the past for SSL certificates, and their U2F support makes me inclined to choose them as my new registrar.
On the other hand, I've heard less than great things about Gandi's reliability and support lately. If you've had to contact their support team, what's your experience been like?
I've never had to contact support, which might be a good thing. Although I did leave them for a while and am in the process of moving my domains to them.
