That's essentially what https://krypt.co/ is...I've used Yubikeys in the past, but have been on Krypton for maybe the past year or so. No problems with it at all, aside from GitHub recently (within the past couple of weeks) not recognizing the authorization despite it working just fine elsewhere. I haven't had a chance to dive deeper into why.

I had not heard of krypton; read over the website based on your suggestion and got excited, but my excitement turned to disappointment when I saw that neither the iOS nor android apps have been updated in nearly 2 years. Makes me wonder if the project is still active or not, and don’t want to invest effort in trying out a tool that’s effectively abandoned.

Wonder if it has anything to do with the project getting acquired by Akamai
