I have to replace my simple.com account, so instead of doing that for a dozen or more subscriptions, I just changed the funding provider in Privacy, and keep the vendor-specific virtual cards.

I love it, I use it for the gyms, my internet provider, the laundry machine provider, any place that I don't trust their data storage, etc.

I have used it and it seems to work pretty well, they just set up a complete integration with 1Password so I trust them because of that as well.

Sometimes the merchant will tell the card is a virtual card and not allow it, but most of the times it works perfect
