Virtual card gets denied because of insufficient funds.

Update: Let me just start with my latest review of this extension- it's mostly broken. Not sure if it's simply related to FIrefox updates, but this extension rarely works these days. It's much more trouble than it's worth. I can no longer recommend its use.

Sadly, there is no other way (that I know of) to generate virtual card numbers without using the extension. So, that means the virtual cards feature is generally not available now.

It's disturbing that a company like Capital One would allow one of their financial products/services to be so unreliable.

Old review:
As usual, reviews are all love or hate (1 star or 5 star). Such absolutism (all-or-nothing think) is rarely useful to anyone. So, first, throw out all of the 1's and 5's and dig deeper into the reviews that have actual thoughtful analysis of the product.

In this particular experience, the Capital One add-on, Eno, is wonderfully useful... when it works. For me, a frequent online shopper, it provides two things I value highly: convenience and security. I love having it available at shopping sites, with all the info I need to complete the purchase. I don't have to look up my card info and manually fill it in. Very nice.

Sadly, some updates to Firefox and a few sites' code break the add-on. But I've found this to be true of many of the add-ons I use. Anytime an app or an operating system pushes out an update, it's not uncommon for software that interacts with it to break or have issues. So, this is not a particular sin of this add-on. It applies to many add-ons.

Most importantly, I love Eno and the feature from Capital One to use a virtual number. The add-on just makes it easier to use. One can still interact with the Capital One website to manage their virtual numbers. Due, once again to occasional breaks from browser updates or particular sites, I have had to get creative when using the feature. This can be frustrating.

It's not perfect, but overall, it works more than it doesn't, and the ability to generate a one-time use number is invaluable when it comes to online security. Keep in mind, the virtual number feature is very flexible. You can keep using the number for that particular site, but lock it, so it's only usable when you allow it, you can just delete it, or leave it unlocked for one particular merchant only (e.g. for a subscription).

If you're not using a virtual number, you are asking to be hacked. Get this add-on, take a deep breath when it breaks from time to time, and feel a whole lot better when you use your credit card online.

worked for a year, but Firefox 85 (and MS Edge) have killed it. Unable to login anymore....

As others have commented, used to work but now unable to authenticate to app. This is with Firefox 85.0. It gets stuck in the authentication step. I deleted all my cookies and cache for *capitalone*. Hopefully gets fixed because it was a very useful feature.

It doesn't work at all. It looks like it is logging in and then it disappears. And the one time I did get it to assign a number, it got rejected by the site I was using. It's a total crock and waste of time and effort.

It just doesn't seem to work at all with Firefox. The extension prompts you to login and pops-up a separate window to enter your credentials, but after entering them it takes you right back to login again. You can run this circle as many time as you like.

This app do not work with Firefox, Chrome or anything. Stop sending emails. DOES NOT WORK

Every time I try to use it, it basically goes away and doesn't allow itself to be used on the page where I thought I'd use it.

App used to work great and I used it all the time. Nowadays this is worthless . For MONTHS have had the same issue everyone else seems to be experiencing. Get in a login loop, entirely unable to actually access or create new card numbers. Team is always "working on it" but never seem to actually accomplish anything.

Tried running the Chrome version of the extension, and get the same behavior there. This is clearly broken, and has gone unfixed for MONTHS. Just complete and utter trash.

Take some pride in your work and fix this.

This extension does not work on sites with CAPTCHA. Had to remove from my browser to use any credit card at my grocery store.

Stopped working in Firefox. It no longer lets me log in. There's no error. It just goes back and tells me I need to log in using the browser.

Doesn't sign in anymore. No other way to make virtual card numbers. This app is a pile of garbage.

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.

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

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.
