What is a Random One-Time Password Generator Tool?
A **Free Online OTP Generator** is a tool that computes Time-based One-Time Passwords (TOTP), which are commonly used as a second factor of authentication (2FA). This **random OTP tool** generates a new 6-digit code every 30 seconds based on a shared secret key and the current time. It's the same technology used by apps like Google Authenticator and Authy.
How to Use This Secure OTP Generator
- Enter Your Secret Key: When you set up 2FA on a website, you are given a secret key. Paste that key into the input field.
- Get Your Code: The tool will instantly generate the current 6-digit code.
- Copy and Use: Click the code or the copy button to use it for your login. A new code is generated every 30 seconds.
Is This Online OTP Generator Secure?
Yes. This is a client-side tool, meaning all calculations happen in your browser. Your secret key is **never** sent to our servers. This makes it a secure and private way to generate codes if you don't have your authenticator app handy.
