Capital One has "Eno"(https://www.capitalone.com/applications/eno/) which provides virtual cards and still works. I'm not a huge fan of Capital One, but afaik they are the only credit card company that offers this.

I should note that Privacy.com provides this service as well and I really do like their mission, but they have the limitation of only being able to be used with a debit card backing the account and I've also ran into some issues with their cards not working with some online vendors.
