About This Tool
This TOTP generator creates Time-based One-Time Passwords compatible with the RFC 6238 standard, commonly used for two-factor authentication. It is designed for developers testing 2FA implementations, security professionals verifying authentication workflows, and users who need a browser-based alternative to authenticator apps. The tool generates codes from a shared secret key with a configurable time step and displays the remaining validity countdown.
How to Use
- 1 Enter or paste the TOTP secret key (base32 encoded) for your account
- 2 Configure the time step interval and code length if they differ from defaults
- 3 View the generated one-time password with a countdown showing remaining validity
- 4 Use the generated code for authentication testing or two-factor login
