Frequently Asked Questions
What is 2FA and why do I need it?
2FA (Two-Factor Authentication) adds an extra layer of security to your accounts. Instead of just using a password, you also need a time-based code generated from your secret key. This makes it much harder for attackers to access your accounts even if they know your password.
How do I get a 2FA secret key?
When you enable 2FA on a service (like Google, GitHub, etc.), they will provide you with a secret key. This is usually displayed as a QR code or as a text string. You can scan the QR code with an authenticator app or manually enter the secret key.
What format should the secret key be in?
The secret key should be in Base32 format (letters A-Z and numbers 2-7). You can enter multiple secrets, one per line. The tool will generate a 6-digit code for each secret that refreshes every 30 seconds.
How often do the codes refresh?
2FA codes refresh every 30 seconds. The timer shown in the interface displays when the next refresh will occur. Codes are automatically updated in real-time.
Can I use this tool offline?
Yes! This tool works entirely in your browser. Your secret keys are never sent to any server - all processing happens locally on your device. This ensures complete privacy and security.
What if I lose my secret key?
If you lose your secret key, you will need to disable and re-enable 2FA on the service that uses it. Always save your secret key in a secure location when you first set up 2FA.
