Generate secure TOTP codes for two-factor authentication
Two-factor authentication (2FA) adds an extra layer of security to your online accounts. Instead of just using a password, you'll need a second form of verification - typically a time-based one-time password (TOTP). This makes it much harder for attackers to gain unauthorized access to your accounts, even if they have your password.
Using our 2FA token generator is simple. Just enter your secret key in the input field above, and we'll generate a secure TOTP code that refreshes every 30 seconds. You can save frequently used secret keys for quick access, and copy tokens with a single click.
A 2FA Token Generator creates time-based one-time passwords (TOTP) for two-factor authentication, providing an extra layer of security for your accounts.
Our generator uses industry-standard TOTP algorithms and processes everything locally in your browser. Your secret keys are never sent to any server.
Your secret key is usually provided when you first set up 2FA on a service. It's often shown as a QR code or a string of letters and numbers.
