Nice while it worked, but then login stopped working - I'd log in using the popup window and it would have no effect so I could never get a number. Needs more QA, apparently.

I used it 1 time and worked fine. Now, not able to use it a second time for a different account/store.
"KEEP YOUR CREDIT CARD NUMBER TO YOURSELF
Eno appears at checkout and provides a unique virtual card number only for that site, allowing you to shop online without exposing your actual credit card number." Did/does not appear.

It seems there is no way to use a virtual card number unless you are using a browser with the add-in AND you are shopping where the merchant has a window open to insert a virtual card number. Citi Cards lets you generate virtual cards and you can use that number anywhere.

For the most part, this seems to work well, but I ran into a very frustrating experience while using this with the HP website today. Basically, it would generate a virtual number, but the number would not properly populate in the order fields - this happens periodically, so the add on allows you to copy and paste manually - not a deal breaker. However, every time I would manually enter the virtual information, Eno would reset the page and default the billing and shipping address to the same thing (which I did not want), as well as either (a) remove the item from the cart or (b) add a second item, with no way to reload the page. I eventually gave up and went to a different browser and used the real card number.

Piece of crap - couldn't send an SMS text message to my phone telling me I didn't own the number!!! I've had the same number since the very beginning of cell service!!!

I used to use this but now when I try to use it I can't. It has become so hard to use it that I just quit using it

useful and works like a charm

Pretty good--awesome, actually--9 out of 10 times. One in a while Eno suggests a card that does not actually work. So I generate a new card, and it does not have a CVV #, so it doesn't work. And when it hangs, it does not give any indication of what the problem is or steps to take to unclog it. Overall, though, I love the security and peace of mind.

This is a frustrating piece of badly written software. I doubt that whoever approved it had ever used any of the apps that do this well. I have fought this thing for a year or more as it insisted on using only one of my 2 enrolled cards and never allowed an option to switch between them. I found out today after a 30 minute call that once a card is used at a business, only that card can be used there in the future. I went through 3 uninstall/installs, and even thought the setup said I'd be able to use either card, that was not true. This thing just does what it wants and has no way for a user to control it to their liking. Citi nailed the virtual card years ago, and Cap 1 should be embarrassed.

Can't get it to work. Says to sign in with the window it opens, I do that, it signs in fine in the opened window, but the plugin window just spins forever. I've turned off every security setting I can think of. Tried Eno on Brave and it worked perfectly fine, no issues.

Used to work perfectly, the last time I tried to use it Enos would not generate a security code. Great idea if it would reliably work.

Love this useful extension - now I can shop online and be certain that the merchant has only the assigned card, not shared. Works very well for creating unique card numbers.

not working on all web sites

Still not working

Originally worked well. Last 2-3 months not work at all. Now, I think I understand why not currently working. Have added on Mozilla again

This add-on is unreliable: some days it works, some other days it doesn't. When it fails, it shows the "sign in" popup in the add-on, I click it, it asks for username and password, then it goes again to the "sign in" popup. I've tried Firefox and Chrome, the add-on in each one as their own quirks. CapitalOne should allow us to generate Eno card in their website too, as a backup method for when this add-on fails.

Great idea, wish it worked. 2 out of 3 vendors I've tried it with say the virtual card number is invalid and the charge is declined.
