This isn’t strictly a privacy question as a security one, so I’m asking this in the context of individuals, not organizations.
I currently use OTP 2FA everywhere I can, though some services I use support hardware security keys like the Yubikey. Getting a hardware key may be slightly more convenient since I wouldn’t need to type anything in but could just press a button, but there’s added risk with losing the key (I can easily backup OTP configs).
Do any of you use hardware security keys? If so, do you have a good argument in favor or against specific keys? (e.g. Yubikey, Nitrokey, etc)
I‘m still working on my setup so your considerations are most helpful. What stands out to me is the option to use an airgapped old crappy laptop to provision the keys. Ideally one with manually disabled modems. That way nobody without physical access should be able to compromise it.
Also, how can you provision your own hw keys?
You can use Yubikey Manager: https://www.yubico.com/support/download/yubikey-manager/
