TOTP / 2FA generator
Generate two-factor (TOTP) codes from a shared secret.
Standard TOTP (RFC 6238) — the same 6-digit codes as your authenticator app. Computed in your browser; the secret never leaves your device.
How it works
1
Enter your secret
Paste the Base32 secret from your authenticator setup.
2
Read the code
The current 6-digit code is shown with a countdown to the next one.
3
Use it
Enter the code to sign in — everything is computed in your browser.
Frequent questions
How does TOTP work?
A time-based one-time password combines your shared secret with the current 30-second time window to produce a short code that both sides can compute independently.
Is it safe to enter my 2FA secret here?
Codes are generated locally and the secret is never uploaded. That said, your TOTP secret is sensitive — only enter it on a device and machine you trust.
