What's a security key?

It's a physical USB device that connects to your computer—like a flash drive but smarter!

Currently Vanguard supports the following keys when using a Chrome browser:

  • Security Key Series (Yubico)
  • YubiKey 4 Series
  • YubiKey 5 Series (excludes YubiKey 5Ci)

How does a security key work?

Before you log on, simply insert your registered security key into your computer's USB port. Then enter your user name and password like you normally would. The key provides an additional level of account security because it uses encryption that only works with our website and you must physically have the key in your possession to log on. You'll use your key every time you log on, or you can use security codes if you don't have your key available.

Where do I get a security key?

You can buy a security key online from External site or Amazon, or you can purchase one from a trusted retailer that sells computer supplies. These keys typically cost between $18 and $50. There are a few different types, so be sure to select one that Vanguard supports: Security Key Series (Yubico), YubiKey 4 Series, and YubiKey 5 Series (excludes YubiKey 5Ci).

How do I register my security key with Vanguard?

Register your security key (logon required)

When you use your registered key for the first time, you may experience a slight delay, as your computer will need to install the appropriate software.

How do I sign in with my security key?

First, make sure you've registered your key with your Vanguard account. Then follow these steps:

  1. Log on to your account like you normally do, with your user name and password.
  2. When prompted, insert your security key into a USB port on your computer. You'll then need to physically touch the key.

Are security keys better than security codes?

While security codes and security keys are 2 different methods of protecting your online financial accounts, they're similar in that both use two-factor verification (also called two-factor authentication or 2FA).

With two-factor verification, there's an extra layer of security that requires not only a password and user name to gain access to your account but also something that only the user has in his or her possession, like a token.

Whether you use security codes (which we send you and you enter when logging on) or a security key (which generates a code that ties your computer to our website), you're using two-factor verification and making it more difficult for cyber criminals to breach your account.

Do I need to register for security codes if I have a security key?

Yes, because if you don't have your key or if you're logging on from a device that isn't compatible, we'll need to send you a security code instead.

What if I don't have my key?

No problem. We'll just send you a security code.

I'm using my key, but I'm being asked for a security code. Why?

If you're signing in from an unsupported browser or device, you'll be asked for a security code instead of your security key.

Will security keys work with financial aggregation services?

Yes, if you're using an aggregation service to help manage your financial accounts, there shouldn't be a problem using your security key.
