Secure Login Fields for Banking Applications
Banks handle the most targeted credentials on the internet. Every login form is a target for XSS, session replay, keyloggers, and browser extensions. SmartField encrypts every keystroke with AES-256-GCM before it touches the DOM.
What Data This Protects
- Passwords
- Account numbers
- Wire transfer details
- PINs
Threats Blocked
- XSS attacks
- Browser extensions
- Session replay (Hotjar, FullStory)
- Keyloggers
- Credential stuffing bots
How It Works
Replace your standard HTML input with SmartField. 2 lines of code:
<script src="https://cdn.smartfield.dev/v1/smartfield.js"></script>
<smart-field type="password" placeholder="password"
encrypt-key="/api/sf-key"></smart-field>
Every keystroke is encrypted with AES-256-GCM. The AES key is wrapped with RSA-2048. Only your server can decrypt.
Why Standard Inputs Fail
A standard <input> stores plaintext in the DOM. Any JavaScript on the page can read it:
document.querySelector('input').value
// "MyBankPassword123" ← stolen
With SmartField, the same code returns:
document.querySelector('smart-field').value
// "eyJ2IjoxLCJpdiI6IkNx..." ← encrypted
Compliance
SmartField helps meet requirements for: PCI-DSS, SOX, GDPR
- AES-256-GCM (NIST SP 800-38D)
- RSA-2048 (NIST SP 800-56B)
- Zero-data architecture. SmartField never sees your data.
Frequently Asked Questions
Does SmartField replace our existing authentication?+
No. SmartField protects the input field itself. Your authentication system (OAuth, SAML, 2FA) stays the same. SmartField ensures that the password never exists as plaintext in the browser DOM.
Is it compatible with banking compliance requirements?+
Yes. SmartField uses AES-256-GCM (NIST SP 800-38D) and RSA-2048 (NIST SP 800-56B). Both are approved for financial data. The zero-data architecture means SmartField never sees your customers' credentials.
What happens if a tracker like Hotjar is on the page?+
Hotjar records DOM content. SmartField stores nothing in the DOM. The screen shows cipher characters. Hotjar captures encrypted symbols, not passwords.
