2FA Code Generator

Automate your Two-Factor Authentication with ease

Tired of manually entering 2FA codes? Beeceptor allows you to upload a QR code image or screenshot and instantly receive the corresponding auth code.

How it works?
  1. Upload a QR code image or screenshot.
  2. Beeceptor analyzes the image, extracts QR code.
  3. The 2FA code is generated and displayed here.

Effortless 2FA Code Generation via API

Programmatically generate 2FA codes with the following APIs. This is ideal for development and testing workflows. Beeceptor stores your secrets and assigns a unique ID for 2FA code retrieval, valid for up to 90 days.

tickSetup the secret

You can generate time-based one-time passwords (TOTPs) for a given. Simply provide the issuer name and secret key in a JSON payload. On success, the API returns the generated OTP and a unique identifier.

POST https://tools.beeceptor.com/2FA/TOTP/

Content-Type: application/json

Request Payload:
{
  "issuer": "your-app.com",
  "secret": "2OLRLATN3OQZOCPA",
  "algorithm":"SHA256"
}

Response Payload: 
{
  "id": "e2cb7165-55a5-44ce-8f7d-c4ff093bcd39",
  "otp": "002881",
  "expiresAt": "2024-05-15T02:46:30.000Z"
}

tickRetrieve 2FA code

Use the generated identifier with this API to generate future 2FA codes using the pre-stored secret. Please note that any unused codes will be automatically purged 90 days after their last usage.

GET https://tools.beeceptor.com/2FA/TOTP/{id}

Content-Type: application/json

Request Payload:
{empty}

Response Payload: 
{
  "id": "e2cb7165-55a5-44ce-8f7d-c4ff093bcd39",
  "otp": "002881",
  "expiresAt": "2024-05-15T02:46:30.000Z"
}

Example: 

GET https://tools.beeceptor.com/2FA/TOTP/e2cb7165-55a5-44ce-8f7d-c4ff093bcd39
The APIs are rate-limited per IP address per minute, and fair usage is expected from the community. For higher usage requirements with paid plans, please contact our support team.

Frequently Asked Questions

What is Two-Factor Authentication (2FA)?
Two-Factor Authentication (2FA) is a security process that requires two distinct forms of identification before granting access to an account or system. It is crucial because it adds an extra layer of security, making it significantly harder for unauthorized users to gain access even if they have one of the credentials.

What security protocols does Beeceptor employ?
Beeceptor encrypts data both at rest and during transmission. It adheres to SOC2 Type II controls. Instead of linking secrets to specific users, Beeceptor assigns each a unique ID for future 2FA code retrieval. Moreover, IP-based rate limiting is implemented to thwart brute force attacks. TOTP secrets stored at Beeceptor are purged if not used for 90 days.

How does Time-Based One-Time Password (TOTP) work as a form of 2FA?
TOTP is a form of 2FA that generates a temporary passcode, which changes at a set interval, typically every 30 seconds. The dynamic nature of TOTP makes it a robust security measure against replay attacks. This tool currently supports generation of TOTP codes.

What are the main differences between TOTP and other forms of 2FA, such as SMS-based verification?
Besides TOTP, other 2FA methods include HOTP, and OTPs via SMS and email. TOTP codes are generated offline and are more secure, as they don't rely on cellular networks like SMS, which can be intercepted more easily.

What are best practices for implementing TOTP in an application?
When implementing TOTP, it's essential to use libraries aligned with RFC 6238 standard, maintain precise time synchronization, and securely store secrets. Additionally, implementing backup recovery options is recommended to help users regain access if they lose their TOTP generator.

Why are QR codes used in setting up 2FA/TOTP?
QR codes are used in the setup process of TOTP to simplify the transfer of secret keys. When setting up a TOTP-based 2FA, the server generates a secret key, which is encoded into a QR code. Users then scan this QR code with a TOTP-generating app on their mobile device, which stores the secret and starts generating OTPs.

What devices can generate TOTPs?
TOTPs can be generated on smartphones and tablets using apps like Google Authenticator, Authy, and Microsoft Authenticator. Hardware security tokens like YubiKey are also capable of generating TOTPs. For software development, testing, and automation, Beeceptor offers a practical alternative.
