2FA code (TOTP)
Paste a TOTP key (or an otpauth:// link) to get the current code. The key is computed right in your browser and never sent anywhere.
Works with Google, email and any TOTP keys; otpauth:// links respect the code length and period.
What is a 2FA code (TOTP)
A 2FA code (TOTP) is a one-time six-digit two-factor authentication code that changes every 30 seconds. It's normally shown by an app like Google Authenticator; here you can get the same code online from the secret key.
How to get the code
- Find the secret key - when you enable 2FA it's shown as a string or a QR code; an otpauth:// link works too.
- Paste the key into the field above and press Get code.
- Copy the six-digit code before the timer runs out.
- Enter the code on the site or app that's asking for it.
FAQ
Where do I get a TOTP key?
The site gives it to you when you turn on two-factor authentication - as a string of letters and digits or a QR code. An otpauth:// link works too.
Is it safe to enter the key on this page?
Yes: the code is computed right in your browser, the key is never sent anywhere - the server neither sees nor stores it.
Why does the 2FA code change every 30 seconds?
That's how the TOTP algorithm works: the code depends on the current time and refreshes every 30 seconds. Enter it before the timer ends.
Are Google Authenticator keys supported?
Yes - keys from Google, email services and any site with TOTP work, as do otpauth:// links that specify the code length and period.
How is this different from an authenticator app?
It's the same TOTP code, just online and without installing an app - handy when your phone isn't nearby.
