Browser FAQs

Why do I need to upgrade my browser?

For security reasons, browsers occasionally stop supporting older versions when new versions are released. To ensure customer security, Capital One may not allow you to access your accounts online using a discontinued browser. When that’s the case, customers need to upgrade to the newer supported version of the browser to continue in online banking.

How do I know if my online session is encrypted?

Web addresses beginning with “https://…” use encryption. The “s” stands for “secured.” Please visit our Commitment to Security page for more information about how we protect you and your online accounts.

What browser settings do I need to use Capital One's website?

Your browser must be able to accept cookies. You will not be able to access any secured pages if you set your privacy setting to ‘Block All Cookies’. You will also need JavaScript enabled to access many of our products and services.

What do I do if my browser is not supported?

While we generally don’t prohibit customers from using browsers not listed in the supported list above, we can’t guarantee that all features will work as expected. We continually test our site with the browsers in the suggested list to make sure the newest versions adhere to our security and usability standards. For the best possible experience, we recommend you use a browser that is listed in the suggested browser list.
