Bank fraud is getting more sophisticated every year. With over 61% of data breaches caused by compromised credentials, protecting your Bank of America account has never been more urgent.

What is a FIDO2 Security Key Card?
A FIDO2 security key card is a small, physical device—often as slim as a credit card—that you use to log in to your online accounts. Instead of typing a password, you simply tap or insert the card to prove your identity. The magic behind it is public-key cryptography, which keeps your login credentials safe and never exposes your secrets online.
Key benefits:
- No passwords to remember or type
- Protects against phishing, brute force, and credential theft
- Fast, simple, and works across devices
Why Bank of America Users Need a FIDO2 Security Key
Bank of America supports FIDO2 security keys for account login, giving customers a much safer way to access their accounts. Here’s why it matters:
- Phishing Resistance: Even if a hacker tricks you into visiting a fake website, your FIDO2 key won’t give up your credentials.
- No More Password Hassles: Forget about forgotten passwords or SMS codes that don’t arrive. Just tap your key and you’re in.
- Works Everywhere: Use your key on your smartphone, laptop, or desktop—no extra software needed.
- Fast Setup: Registering your security key with Bank of America takes just a few minutes.
How FIDO2 Security Keys Work
Here’s a quick look at how FIDO2 authentication keeps your account safe:
- Registration: When you set up your key, it creates a unique cryptographic key pair. The public part is shared with the bank; the private part stays on your key and never leaves it.
- Login: When you want to sign in, the bank sends a challenge. Your key signs it with your private key, proving you’re really you.
- Verification: The bank checks the signature using your public key. If it matches, you’re in—no password needed.
The Growing Importance of FIDO2 Security Keys
The FIDO2 authentication market is booming. In 2025, it’s valued at $1.82 billion globally, with a projected annual growth rate of 23.2% through 2033. Banking and finance are leading the way, as more institutions demand robust, user-friendly security solutions.
Key stats:
- Over 35% of people had at least one account compromised due to password weaknesses in the past year.
- 54% of users familiar with passkeys say they’re more convenient than passwords.
- 53% believe passkeys are more secure than traditional logins.
