Not all. A major US Bank (rhymes w/ Pace Bank) used to provide this feature back in the 2000s and then rolled it back. I discovered this ~4 months ago when I wanted to buy something online but didn't fully trust the vendor. Then ended up going with Privacy.com.

I'm a huge fan and would def recommend them to anyone looking for better control over subscription charges

CapOne offers that for their credit cards, but it's so clunky and unintuitive that I still wind up using Privacy 90% of the time.

I have a Capital One card and wanted to use that feature. As far as I could tell, the only way to use it was to install their "assistant" browser extension and give it permission to view everything you do. Then if you were on a merchant site it could suggest you use a new card number for it. I considered toggling the assistant on and off just as needed but instead said nope. Was there another way to do it?

Totally bogus, isn’t it? I just did that very thing with CapOne. The only saving grace is that once you create the temp card with their definitely-not-spyware web browser extension, you can uninstall it completely and manage the card through the website. I’ve installed it, visited a single site, and uninstalled it several times so far and it seems to get the job done.

You can give selective access[0] to the extensions in Chrome. The restrictive access is that it will get access to the webpage only when you click the extension. Read under "Let extensions read and change site data"

Apple Card does this (and obviously Apple Pay in general). It's not nearly as powerful as Privacy though since the card numbers can't be cancelled or paused from what I can tell.
