Question 1

What is this 2FA Generator?

Accepted Answer

2FA Generator is an online tool to generate TOTP (Time-based One-Time Password) codes for two-factor authentication. It works like Google Authenticator, but in the browser—so you don't need to install an app.

Question 2

Is it safe to use?

Accepted Answer

Yes. Your secret key stays in your browser (URL) and is processed locally on your device. We don't store or send your secret key to the server, so your privacy remains intact.

Question 3

How do I use it?

Accepted Answer

Paste the secret key from the service you're protecting (for example, from Google or GitHub 2FA setup), click Generate Code, and a 6-digit code will appear. The code is valid for 30 seconds and refreshes automatically.

Question 4

Does it work for all services?

Accepted Answer

Yes. It supports any service that uses the TOTP standard (RFC 6238), including Google, Microsoft, GitHub, AWS, Cloudflare, Discord, and many more.

Question 5

Is it free?

Accepted Answer

It's 100% free and open-source. You can use it, modify it, and even self-host it at no cost. The source code is available on GitHub.
