Secure Your Accounts with the TOTP Secret Generator
Take control of your digital security with the TOTP Secret & Backup Code Generator. This utility allows you to create cryptographically secure 2FA secrets and emergency recovery codes entirely within your browser. By leveraging the Web Crypto API, all generation happens locally on your device, ensuring your sensitive keys are never transmitted to a server or exposed to the cloud.

Frequently Asked Questions
Are my 2FA secrets stored on your server?
No. This tool uses a “Zero-Server” architecture. Your secrets and backup codes are generated locally using your browser’s Web Crypto API and are never transmitted over the internet.
Is this tool compatible with Google Authenticator and Authy?
Yes. The tool generates standard Base32 secrets, which are the industry standard for TOTP apps including Google Authenticator, Authy, Microsoft Authenticator, and 1Password.
Why do I need backup codes?
Backup codes are emergency keys used to access your account if you lose your phone or 2FA device. You should store them in a secure, offline location like a physical safe or a password manager.
Can I use this tool while offline?
Yes. Once the page is loaded, the cryptographic functions run entirely within your local browser environment without needing an active internet connection.
Does this tool support 160-bit secrets?
Yes, we generate 20-byte (160-bit) random buffers to ensure high entropy, providing maximum security for your two-factor authentication setup.
What happens if I forget to save my codes?
For security reasons, we do not store your data. If you close the tab or wipe the session before saving, the keys are lost forever and cannot be recovered by us.
