OVH is always an exercise in broken UI including terms of service that seem to be copied from a pdf and have random artifacts. It's probably the worst buying experience I've had since the naughties and nothing changed in the years I'm with them now.

...but they're cheaper than other registrars known for being cheap, and I've monitored their nameservers (and a few others') for nearly a year before switching away from my previous registrar and they were consistently fast whereas others had spikes, outages, or constantly round robined across oceans or some such.

Quality servers at very low prices makes me put up with some broken UI for a few minutes per renewal.

OVH is cheap and supports U2F. I have a bunch of stuff with them.
