MFA Implementation Methods

SMS Verification

SMS-Based Authentication: SMS verification sends one-time codes to registered phone numbers for second-factor authentication during login or sensitive operations.

Configuration Options:

• Phone number verification and registration workflows

• SMS provider integration (Twilio, AWS SNS, MessageBird)

• Message template customization for branding consistency

• Rate limiting and abuse prevention for SMS delivery

• Fallback mechanisms for SMS delivery failures

Security Considerations:

• SIM swapping vulnerability mitigation strategies

• SMS interception prevention through encrypted delivery

• Phone number verification requirements

• International SMS delivery reliability

• Cost management for high-volume SMS authentication

Time-Based One-Time Passwords (TOTP)

TOTP Authentication: TOTP generates time-synchronized codes using authenticator applications like Google Authenticator, Authy, or Microsoft Authenticator.

Implementation Features:

• QR code generation for easy authenticator app setup

• Backup code generation for device loss scenarios

• Time window configuration for code validity periods

• Algorithm customization (HMAC-SHA1, HMAC-SHA256)

• Multiple device support for user convenience

Enterprise TOTP Configuration:

• Corporate authenticator app recommendations

• Centralized backup code management

• Admin override capabilities for locked accounts

• Bulk user enrollment procedures

• Device management and security policies

Biometric Authentication

Biometric verification uses unique physical characteristics like fingerprints, facial recognition, or voice patterns for secure user authentication. ProofGrid integrates with device-native biometric capabilities and hardware security keys to provide seamless, secure authentication experiences.

Biometric Verification Methods:

• Fingerprint authentication through device sensors

• Face recognition using device cameras

• Voice recognition for phone-based authentication

• Hardware security key support (YubiKey, FIDO2)

• Platform-specific biometric integration (Touch ID, Face ID, Windows Hello)

Enterprise Biometric Policies:

• Device compatibility requirements and testing

• Biometric data privacy and storage policies

• Fallback authentication for biometric failures

• Corporate device management integration

• User enrollment and training procedures

fromNumber: '+1234567890'

},

};

// Send SMS verification code

const sendSMSCode = async (phoneNumber) => {

const response = await proofgrid.mfa.sendSMS({

phoneNumber: phoneNumber,

config: mfaConfig

});

return response.messageId;

};

// Verify SMS code

const verifySMSCode = async (phoneNumber, code) => {

const verification = await proofgrid.mfa.verifySMS({

phoneNumber: phoneNumber,

code: code

});

return verification.success;

};

// TOTP MFA setup and verification

const setupTOTP = async (userId) => {

// Generate secret key for user

const secret = await proofgrid.mfa.generateTOTPSecret(userId);

// Generate QR code for authenticator app

const qrCode = await proofgrid.mfa.generateQRCode({

secret: secret,

label: `ProofGrid:${userEmail}`,

});

// Generate backup codes

const backupCodes = await proofgrid.mfa.generateBackupCodes(userId);

return {

secret: secret,

qrCode: qrCode,

};

};

// Verify TOTP code

const verifyTOTP = async (userId, code) => {

const verification = await proofgrid.mfa.verifyTOTP({

userId: userId,

code: code,

window: 1 // Allow 1 time step tolerance

});

return verification.valid;

};

// Conditional MFA based on risk assessment

const evaluateMFARequirement = async (authContext) => {

const riskFactors = {

newDevice: authContext.deviceFingerprint.isNew,

unusualLocation: authContext.ipGeolocation.isUnusual,

privilegedUser: authContext.user.role === 'admin',

sensitiveAction: authContext.action.requiresElevation

riskFactors.privilegedUser ||

riskFactors.sensitiveAction;

return {

mfaRequired: requireMFA,

riskScore: calculateRiskScore(riskFactors),
