And finally recovery_codes, if the user loses access to their authenticator app, they can input these recovery codes into the /v1/totps/recover endpoint at any point. You can embed this directly into your website and it will display as a QR code that users can scan. The qr_code is the base64-encoded representation of the QR code image. The totp_id is the Stytch identifier for a given TOTP instance. The secret is shared between the authenticator app and your server. This endpoint returns four unique fields in addition to the stand fields like status_code and request_id. Defaults to 1440 (1 day) with a minimum of 5 and a maximum of 1440 (1 day). Make sure to expeditiously prompt the user to complete the TOTP flow quickly after TOTP creation. The newly create TOTP instance must be authenticated at least once within this timeframe otherwise it will expire and be render unusable. ![]() ![]() This endpoint also takes in an expiration_minutes value this value is the expiration for the TOTP instance. Next, you’ll want to create a TOTP for the user by passing the user_id into the /totps/create endpoint. "email": Step 2: Create a TOTP for the user The user_id will be used to register and authenticate with TOTP. Pass the user’s email address or phone number into the User create endpoint and store the returned user_id. If the user attempting to register isn’t already associated with a Stytch user_id, you’ll need to create a Stytch User with the /users/create endpoint. Once the user supplies the TOTP code, your app can use Stytch’s /totps/authenticate endpoint to verify that passcodes are valid and ultimately grant users access. Users, who must have an authenticator app downloaded on their device, are asked to input the unique passcode within a certain period of time, usually 30 seconds, as evidence of their identity. It works by generating a one-time passcode that’s based on the current time and a shared secret between an authenticator app like Google Authenticator or Authy, and the server (in this case, Stytch). When integrated as a second authentication factor, TOTP serves as an additional safeguard by requiring users to prove possession of their device. TOTP authentication solutions are ideal for particularly sensitive use cases that are also highly attractive in terms of the potential payoff they offer – think money movement in fintech or cryptocurrency, or access to a company’s HR or payroll information. Time-based one-time passcodes (TOTP) are a passwordless two-factor authentication option that can be used when you need high security assurance. Setting up time-based one-time passcodes (TOTP)
