How 2FA Works
Two-factor authentication adds a second step after your password to confirm that the person logging in is really you.
The basic concept of two-factor authentication
2FA combines two different verification factors. Usually that means something you know, like a password, plus something you have, like a phone or authenticator-generated code.
This makes account takeovers harder because a stolen password alone is not enough.
Where TOTP fits into 2FA
A TOTP generator creates the second factor code. During login, you enter your password first and then submit the six-digit code generated from your shared secret.
This workflow is common across developer tools, email platforms, crypto exchanges, and admin dashboards.
- Enter your username and password
- Open your authenticator or browser-based generator
- Get the current code
- Submit the code to finish login
