I've rarely had technical problems with the extension itself. Sometimes the auto-paste doesn't work because of the web page's cart design, but it's easy enough to copy and paste. I only gave it a 4 star because I don't like having any extension collecting data about every site I visit. What I do is I disable the extension any time I'm not actually making a purchase, and that works just fine.

Pops it up. Log in to my Capital One account. Create a virtual card number for each website. Identify who is charging you, and be able to lock each virtual number virtually. Most secured way to shop online these day.

When it works, I give it a 5/5. The problem is it works MAYBE 2% of the time. The other 98% I have to try refreshing the page, signing in 500 times, uninstalling and reinstalling, signing in another 500 times, it's such a hassle to use I just log into my account and manage it that way instead of using the extension because it never works!!!

Can't pass mobile number verification step. Always get "Something Wrong" error. I have a valid mobile number used everywhere.

I am so sick and tired of the pain of using this app. Every time I log on it's like I've never used it all these years. I have to "add" the extension but first verify AGAIN it's me then add the extension then login AGAIN. Most times I have to enter capitol one and login then open eno virtual cards to get it to work. All and all you could probably pay me the $Millions you're paying your "developers" and "maintainers" and get a better product. So sick of ZERO customer service.

I love this because I know my actual card won't be compromised and need to be replaced in case a merchant has a security breach. I've been using Eno for several years now.

When this extension works, it's great! It helps protect my security online.

However, it seems to regularly get stuck authenticating into Capital One, freezing up and preventing me from logging in. Sometimes I'll launch the checkout page in Chrome (blech!) and use the extension in Chrome instead, which seems to be less prone to freezing up.

I've tested this sporadically over the years, and I've never been able to log in. I've disabled ad-block and site security. I've even tried the Chrome version, and I cannot ever log in.

One less thing to worry about when it comes to making online purchases. I use it to pay all of my bills too and like how the virtual wallet is set up. Reading the negative reviews, it was only associated with problems opening the extension. I do not know if this will help others, but you go to the upper right hand corner and hit the "Extensions" tab and from there choose to open Eno and it automatically generates a card. This is an extra step as with Chrome it would open automatically when you needed it.

Super useful to use virtual cards on websites!
