Two-Factor Auth — Nexus Market

Two-Factor Authentication (2FA) adds a critical layer of security to your Nexus Access account. This goes beyond a simple password, requiring a second verification step to log in. Implementing 2FA significantly reduces the risk of unauthorized access, a lesson learned from past market compromises like the AlphaBay incident.

TL;DR: Enable two-factor authentication on your Nexus Access account for enhanced security. This involves setting up a PIN and integrating PGP. Follow the steps below to secure your login.

Securing Your Nexus Access Account

Account Security Checklist

  • Strong, Unique Password: Use a password generator. Never reuse passwords across sites.
  • PIN Setup: Create a distinct PIN for Nexus Access.
  • PGP 2FA: Integrate your PGP key for login verification.
  • Logout Discipline: Always log out when finished.
  • Session Management: Review active sessions regularly.

Enabling PGP 2FA

This process requires you to have a PGP key pair already generated and imported into your Nexus Access profile. If you haven't done this, you must complete that first.

  1. Navigate to Security Settings: Find the 'Security' section within your Nexus Access account.
  2. Locate 2FA Options: Select the 'Two-Factor Authentication' or 'PGP 2FA' setting.
  3. Enable PGP Verification: Follow the on-screen prompts to activate PGP as your second factor. This may involve re-entering your password or PIN.
  4. Save Changes: Confirm your settings.

Testing Your 2FA Setup

After enabling PGP 2FA, it is crucial to test the login process.

  • Log out of your Nexus Access account.
  • Attempt to log back in.
  • You should be prompted for your password/PIN and then your PGP key's passphrase.
  • Successfully logging in confirms your 2FA is active and correctly configured.

Two-Factor Authentication Methods

Nexus Access supports multiple layers of authentication to safeguard your account.

Method Description Security Level
Password Your primary login credential. Basic
PIN A secondary numeric code for login verification. Medium
PGP Key Cryptographic proof of identity via your private key. High

Best Practices for 2FA

  • Keep PGP Private Key Secure: Treat your private key like a password. Anyone with access can impersonate you.
  • Regularly Review Security Settings: Periodically check your account for any unauthorized changes or active sessions.
  • Utilize Market-Specific Security Features: Nexus Access's PGP integration is a robust defense, similar to what was seen on markets like Silk Road.
