Even if yubikey has a 2fa authenticator, this would make it much simpler to use

We play https://run3donline.com much these days. There's a simple reason for this: our kids are older now.

A variety of soft/hard options ought to be supported in 2022. Get with the program DO.

This is almost a deal-breaker for me. Really don't want to switch to AWS, but not willing to compromise on security for my users. The best option DO has for 2FA right now is TOTP. Please implement Yubikeys at the very least.

Adding my vote as well. The Rogers outage in Canada meant that many folks could not receive SMS 2FA codes. Being locked out of your accounts for a day could be disaster for many companies, and recovery codes need to be used with care and aren't always so readily available.

Adding my vote in favor of hardware key support - this would be a great addition to an already-great service.

Agreed. DigitalOcean's competitors have it, it needs to have it too.

Just adding to the noise. Would really love to have support for hardware key login

Personally, in addition to increased security, it is useful to have the option of a separate, not private device to authenticate to work related accounts and services.

U2F has morphed into webauthn, which has tonnes more devices support, so you will have an even larger base of users who will benefit from this
