TOTP Generator
Generate Time-based One-Time Passwords for secure 2FA authentication
🔑 Secret Management
⚙️ TOTP Configuration
✅ Code Validation
Validation Notes:
- Codes are valid for the configured time window (usually 30 seconds)
- Previous and next time windows may also be accepted for clock skew tolerance
- Each code can typically only be used once

⏱️ What is TOTP?
Time-based One-Time Password (TOTP) is a computer algorithm that generates a one-time password using the current time as a source of uniqueness. It's widely used for two-factor authentication (2FA) by services like Google Authenticator, providing an extra layer of security for your accounts.
🔐 How It Works
TOTP uses a shared secret key and the current time to generate 6-digit codes that refresh every 30 seconds. The algorithm combines your secret key with the current time window using HMAC-SHA1 cryptography to produce unique, time-sensitive passwords that expire quickly.
🛡️ Security Benefits
Even if someone knows your password, they can't access your account without the current TOTP code from your device. This significantly reduces the risk of unauthorized access, as attackers would need both your password and physical access to your authenticator device.
📱 Compatibility
Our TOTP generator is compatible with all major authenticator apps including Google Authenticator, Authy, Microsoft Authenticator, and others. You can generate QR codes for easy setup or manually enter the secret key into your preferred authenticator app.
📝 How to Use the TOTP Generator
Get Secret Key
Generate a new secret key or import an existing one via QR code, manual entry, or Google Authenticator backup.
Configure Account
Enter your account name and issuer information for easy identification in your authenticator app.
Generate QR Code
Create a QR code to easily add the account to your mobile authenticator app by scanning.
Verify & Use
Test the generated TOTP codes and use them for secure two-factor authentication on your accounts.
