2FA / TOTP Code Generator (Private, Browser-Based)

2FA code (TOTP)

Paste the Base32 secret from your account’s two-factor setup (the text key if you cannot scan the QR code). We show the same 6-digit code an authenticator app would—everything stays in your browser.

Secret key (Base32)

Current code

—— ——

Standard 30-second time step and 6 digits. If a site uses different settings, codes may not match. Never share your secret; treat it like a password.

Privacy

Your secret and generated codes are not sent to eSafe servers. Generation uses Web Crypto (HMAC-SHA1) in this tab only.

Online TOTP / 2FA code generator (Base32 secret)

TOTP (time-based one-time password) is what most sites mean by authenticator app codes: a 6-digit number that changes every 30 seconds, derived from a shared secret. This page is a browser-based 2FA code tool: paste your Base32 secret to get the current 6-digit 2FA code without installing an app—handy on a trusted device when you only have the manual setup key.

Security notes

Your secret is as sensitive as a password. Prefer a dedicated authenticator or password manager on a device you control; use this TOTP generator only on a safe machine over HTTPS. Combine 2FA with unique passwords and safer browsing—eSafe helps you monitor risky extensions and protect checkouts.
