Some credit card companies have card generators (Capital one has Eno, Amex has one I believe, Citi calls it Virtual Card Generator etc) but you can also use privacy.com, revolut and I think there's an app called token or something?

I think I pay for everything online with my privacy cards now. It's just easier to keep track of stuff when you get alerts after a company charges a closed card, or tries to charge you more than your card limit that you set up.

There a few options for virtual cards. Ive been using https://privacy.com/.

I’ve been using this not only for subscriptions, but also when I’m making an online purchase at a store that I think may not have the best security in place.

I only use virtual cards for online payments. I use Citi and they have an option to generate a card with specific amount and expiry.

Last I checked, Citi's virtual card feature inexplicably requires Flash. I was like "I thought that was dead?"

This was true for Bank of America, too, at least in December 2018.

They killed the feature altogether.
