Capital One App & Browser Help

Technical Help With the Capital One App and Website

This page is about your device, not your money. If the Capital One app will not install or open, or the website will not load properly in your browser, those are technical problems we can help you work through.

Everything to do with your actual account — balances, transactions, cards, payments, disputes or fraud — must go to Capital One directly, using the number on the back of your card or their official app. We have no access to your banking and we will never ask you about it.

Device and browser problems we can help with

• App failing to install, crashing on launch, or stuck on a loading screen.
• Website not displaying correctly, or buttons not responding, in your browser.
• Out-of-date browser or operating system blocking the site.
• Setting up the app again after changing phones.
• Push notifications or biometric unlock not working on your device.

Things to try first

• Update the app through the official Apple App Store or Google Play.
• Clear your browser cache and retry in a private window.
• Disable browser extensions temporarily to rule them out.
• Restart the phone or computer fully.

A word about fraud

Be very careful who you talk to about a bank account. We will never ask for your Capital One username, password, PIN, card number, security code or a one-time passcode — and neither will Capital One over an unsolicited call. If you think your account has been compromised, stop and call the number printed on your card straight away.
