Why TOTP?

Why Choose TOTP Authentication

App-based authentication that works anywhere, anytime — even without internet connectivity.

Works Offline

No network connection needed. Codes are generated locally on the user's device using a shared secret.

Authenticator App Compatible

Works with Google Authenticator, Microsoft Authenticator, Authy, and any TOTP-compatible app.

QR Code Provisioning

Simple one-time setup — users scan a QR code to link their authenticator app in seconds.

Time-Based Rotation

Codes automatically rotate every 30 seconds using the HMAC-SHA1 algorithm, following RFC 6238.

Phishing Resistant

TOTP codes are device-bound and time-limited, making them significantly harder to intercept or replay.

Recovery Codes

Generate backup recovery codes during setup so users never lose access to their accounts.

How TOTP Works

A simple four-step flow from secret generation to code verification.

01

Generate Secret

A unique secret key is generated for each user and stored securely. This forms the basis of the TOTP algorithm.

02

QR Code Scan

Present the secret as a scannable QR code. Users add it to their preferred authenticator app in one tap.

03

User Enters Code

When authenticating, users enter the 6-digit time-based code currently displayed in their authenticator app.

04

Server Verifies

Authentica verifies the code against the shared secret and current time window, confirming the user's identity.

Integrate TOTP in Minutes

Our SDK handles secret generation, QR code creation, and verification — so you can add TOTP to your app with just a few lines of code.

Generate TOTP secrets with one API call
Get provisioning URIs for QR code rendering
Verify codes with time-window tolerance
Generate and manage backup recovery codes
totp-setup.js
const authentica = require('authentica-sdk');
const client = authentica.init({
apiKey: process.env.AUTH_KEY
});
// Generate TOTP secret & QR provisioning URI
const { secret, qrUri } = await client.totp.setup({
userId: 'user_123',
issuer: 'MyApp'
});
// Verify a user-submitted TOTP code
const result = await client.totp.verify({
userId: 'user_123',
code: '847291'
});
// result: { valid: true, window: 0 }

Use Cases

TOTP is ideal for scenarios requiring strong, offline-capable authentication.

High-Security Accounts

Developer Platforms

Secure developer consoles, API key management, and CI/CD pipelines with TOTP — the industry standard for protecting critical infrastructure.

Enterprise SSO Supplement

Add TOTP as a second factor alongside SSO for enterprise employees, meeting compliance requirements for multi-factor authentication.

Regulatory Compliance

Satisfy SAMA, PCI-DSS, and PDPL multi-factor authentication mandates with standards-compliant TOTP implementation.

Corporate VPN Access

Require TOTP verification for VPN and remote access connections, ensuring only authorized employees connect to internal networks.

Shared Account Protection

Enable per-user TOTP enrollment on shared or service accounts, maintaining accountability and individual audit trails.
