Online security features and technologies

Check out some of the ways we protect you online.

Web browser technologies

Most web browsers have built-in features to help keep you safe.

To access your accounts through, your computer's web browser must support, at a minimum, Transport Layer Security (TLS) version 1.1. This technology provides strong security and privacy when you access account information, initiate online account transactions, or send secure messages.

"Green bar" reassurance
Vanguard passed an independent and rigorous audit to get an "extended validation" Secure Sockets Layer (SSL) certificate from Comodo, a leading internet security authority. This type of SSL certificate can help prevent "phishing" attacks when you use certain browsers by highlighting the web address bar in green and showing the real company name when you access trusted websites, such as

Logon protection

We use these features to help secure your logon session.

User name and password protection
After a limited number of unsuccessful logon attempts, Vanguard will disable your password as a precaution. If your password is disabled, you can restore access through our website or by calling Vanguard.

Security questions
You'll be asked one of the security questions you chose if you log on from a computer or personal device we don't recognize, or if you perform certain sensitive transactions.

Other security methods

We take extra steps to help secure your account online.

A time-out feature
Secure areas of our site have built-in timers that terminate your access after a specified amount of time to help reduce the possibility of unauthorized access from an unattended computer or device. Reminder: When you finish viewing your account information, log off the site and close your browser or mobile app.

Masking bank account numbers
To prevent unauthorized users from viewing your bank account number online, we'll only display the last four digits of your account number; preceding digits will be masked by asterisks.

Extra verification
We'll send confirmation letters or emails when changes are made on your account. If you receive a letter or email confirming a change you didn’t authorize, contact Vanguard immediately at or 877-223-6977.

In addition to these safeguards, Vanguard will never:

  • Send an unsolicited email asking you to respond with your personal account information (such as user name, password, or Social Security number).
  • Ask for your web password in an email or request via phone or U.S. mail. We may ask for personal information if you're having trouble logging on to

Note: A security alert could indicate that either the date on your computer is incorrect or you're using an older version of your web browser. Please contact Web Technical Support Services for assistance.
