Why You Should Use a YubiKey to Protect Your Vanguard Account
Your Vanguard account likely holds more than just numbers, it holds your future. From retirement savings to brokerage assets, it is a prime target for hackers.
Vanguard offers built-in protections and services like:
- Security codes sent via SMS or voice call.
- Two-factor authentication (2FA) via mobile device.
- Support for physical security keys like the YubiKey.
But here’s the problem: Text messages can be intercepted. Phones can be SIM-swapped. Even authenticator apps can be tricked.
All security experts agree: if you’re going to use 2FA, a physical security key is your best option.
And that’s where the YubiKey comes in. Taking this action and enhancing your cybersecurity strategy might be the smartest thing you do for your financial future this year.
How YubiKey Works
A YubiKey is a small hardware device that becomes your second layer of identity verification. You tap it during login, physically proving it’s you. No device? No access.
Here’s why it matters:
- It’s immune to phishing and cyber attacks
- It works instantly; No batteries and internet needed
- It’s faster and more secure than any SMS or app-based code
Once connected to your Vanguard account, the YubiKey becomes your gatekeeper. And if someone tries to access your account without it? They’re blocked and locked out.
Without this hardware 2FA in place, a hacker could:
- Transfer your funds;
- Access sensitive tax records;
- Change your email and lock you out completely;
You can’t afford that kind of exposure.
What You’ll Need to Get Started
Before jumping into setup, here’s what you need on hand:
- ✅ Your Vanguard account login
- ✅ A mobile phone (required for initial 2FA setup)
- ✅ A FIDO2-compliant security key like the YubiKey 5 NFC
- ✅ (Optional but recommended): A second backup key (e.g. YubiKey 5Ci)
- ✅ (Optional) The Vanguard app for managing your account and setting up security features
Getting started is easy. Just log into your Vanguard account security center, register your phone number (required), and follow the steps to link your YubiKey.
Completing the setup process ensures that your account is protected by the YubiKey’s robust security features.
Going forward, your login becomes:
- Enter your username and password
- Tap your YubiKey
- You’re in, securely!
Users can choose to be remembered by the system to bypass the security code step during future logins, enhancing user experience while maintaining security.
Step 1: Log in to Vanguard
Visit investor.vanguard.com and sign in with your existing username and password.
If prompted, provide secure answers to any security questions you’ve previously set up, as compromised answers can pose significant risks. Users might need to follow specific steps for better security management.
Step 2: Access Your Security Settings
Once inside your dashboard, look to the upper right corner and click the small profile icon near “Log Off.” This will take you to your profile and account settings.
From there, click on the “Security” tab. Scroll to the bottom of the Security section until you see the option for “Security key”. This is where you can manage your security keys, such as the YubiKey, to add an additional layer of protection to your account.
Users can also manage their security settings through the Vanguard phone app by following specific steps.
Step 3: Register for Security Codes (Required by Vanguard)
Before you add a security key, Vanguard requires that you enable basic two-factor authentication via your mobile phone number.
- Enter your number when prompted
- Receive and enter the 6-digit SMS code
- You may be asked for a backup number. This is optional and can be skipped. If you change your phone number, update your security settings to ensure security codes are sent to your new phone number for account verification.
Yes. SMS is required to activate stronger 2FA, but that’s currently how Vanguard handles initial verification. You will be able to remove the SMS 2FA once the security key is set up (and this is recommended if you’re willing).
Step 4: Start Security Key Registration
After your phone is verified, go back to your profile settings → Security → Security key.
Before proceeding, Vanguard will show a Terms of Use page. Note that you must scroll to the bottom to enable the “I Agree” button.
(If you don’t scroll, you won’t be able to proceed!)
Step 5: Confirm Identity Again
Before registering the key, Vanguard will ask you to verify your phone number again.
You’ll receive a second SMS code. Enter it to confirm that you’re authorized to add security keys to your account.
Step 6: Insert and Register Your YubiKey
You’ll now be prompted to name your key. For example, you could call it “YubiKey 5 NFC.”
- Insert your YubiKey into your USB port, or tap it to your phone if it supports NFC
- Press the gold button on the key to complete the registration
- If your password manager prompts you to save a passkey, ignore or decline. This isn’t a password to store
✅ Success! You’ll now see a confirmation message that your first security key is active.
Step 7: Add a Backup YubiKey
Adding a second key is optional, but strongly advised in case you lose your primary.
Repeat the process above to register your backup device:
- Scroll to the bottom of the Terms again
- Click I Agree
- Name your key (e.g. “YubiKey 5Ci”)
- Insert and tap the key to finish registration
Now you have both your primary and backup security keys secured on your Vanguard account.
What Changes After You Enable YubiKey for Vanguard
Once setup is complete, you’ll notice a new login flow:
- Enter your username and password
- Instead of answering a question or entering a code, you’ll be prompted to insert or tap your YubiKey
- Tap the key and you’re in!
If you decline to use a YubiKey, you may be leaving your account vulnerable to potential security threats.
Using a YubiKey is fast, secure, and removes weak links like SMS or app-based codes by incorporating two factor authentication.
Your Vanguard Account Is Just the Beginning
Securing your Vanguard account with a YubiKey is a smart move, but why stop there?
The same hardware key you used to protect your investments can also lock down the rest of your digital life.
Many popular platforms now support physical two-factor authentication, including:
✅ Apple iCloud: Protect your Apple ID and all synced devices
✅ Facebook: Stop account hijacks and unauthorized logins
✅ 1Password: Add an extra layer of protection to your entire vault
In fact, you can use your YubiKey to secure dozens of accounts across finance, cloud storage, email, and more.
