Topcoder MFA Enablement Guide

Starting July 10, 2025 to better protect your accounts and personal data, we are now enforcing Multi-Factor Authentication (MFA) on the Topcoder platform. Setting up MFA is required before completing registration or your first login on Topcoder. This step is mandatory for both new and existing users.

Note: Existing users will be prompted to set up MFA when they log in.

During the sign-up process, MFA setup will be requested after the account activation is completed.

How to Set Up Your MFA

MFA Methods Available:
You can begin setting up MFA by choosing an authenticator app, such as Google Authenticator, Authy, FreeOTP, Microsoft Authenticator or a similar option.

Google Authenticator setup:

To set up Google Authenticator:

• Select the Google Authenticator (or similar) option.

• Scan the QR code using your preferred authenticator app.

• Enter the one-time code generated by the app.

If you’re unable to scan the QR code, you can manually input the provided setup key into your app and then enter the one-time code generated.

After successful verification, you’ll receive a recovery code. This can be used to log in when your device is unavailable. Be sure to save it somewhere safe.

Please note: a new recovery code is generated each time one is used.

You’ll also be asked whether you’d like to enable quick login using the current device’s fingerprint or face recognition. If you trust the device, you can accept this option. Alternatively, you may choose Remind Me Later or Not on This Device.

If you proceed with biometric login, you can log in using your fingerprint or face recognition instead of the one-time code in future sessions.

MFA setup is now complete!

Login Methods After MFA Setup:

Once MFA is set up, you can log in using any of the following methods:

• Google Authenticator (or similar app)

• Email

• Recovery code

• Fingerprint or Face Recognition. (if previously enabled)

Why MFA Matters

Enabling MFA helps protect your account even if your password is compromised. With this added layer of security, you can participate in challenges and access your data with greater peace of mind.
