After signing up and confirming your email, you are required to set up two-factor authentication (2FA). This ensures that your domains and valuable assets are protected, making it impossible for anyone to access them without the second factor—typically your smartphone. Click [here](https://help.opusdns.com/what-is-multi-factor-two-factor-authentication-mfa/2fa-and-why-is-it-required-after-sign-up?hsLang=en) to learn more about how 2FA works and why it keeps your portfolio secure. ### 1\. Install an authenticator app We recommend using an authenticator app on a mobile device that you typically carry with you. Well-established and commonly used options include: - Google Authenticator - FreeOTP - Microsoft Authenticator Other authenticator apps can also be used. However, the ones listed above are among the most widely supported and easiest to use. ### 2. Scan the QR code to set up access in your authenticator app Scan the QR code provided by us, which creates a new entry for your account within the app. The authenticator app continuously generates a **six-digit code, known as a one-time password (OTP)**, which is valid only for a short period—typically 30 to 60 seconds. Enter your code and additionally assign a custom name to the device on which the app is configured. For security reasons, the code changes frequently and cannot be reused. ![2fa](https://help.opusdns.com/hs-fs/hubfs/2fa.jpeg?width=670&height=461&name=2fa.jpeg) ### 3\. Log in using the one-time password (OTP) from the app For all future logins, after entering your username and password, you will be asked to provide the one-time password (OTP) from the authenticator app you set up. This ensures your login remains highly secure, keeping your domain portfolio safe.   **Important:** No code is sent via SMS, WhatsApp, email, or any other messaging service. You must actively open the authenticator app and enter the displayed code manually.     [![Knowledge Base Banner\_ 3 Dark](https://help.opusdns.com/hs-fs/hubfs/Knowledge%20Base%20Banner_%203%20Dark.jpg?width=670&height=174&name=Knowledge%20Base%20Banner_%203%20Dark.jpg)](https://app.opusdns.com/signup?utm_source=knowledgebase&utm_medium=referral&utm_campaign=signup&utm_content=cta_banner) - [Create your OpusDNS account](https://help.opusdns.com/create-your-opusdns-account?hsLang=en#main-content) - [Open Your Account](https://help.opusdns.com/create-your-opusdns-account?hsLang=en#open-your-account) - [FAQ](https://help.opusdns.com/create-your-opusdns-account?hsLang=en#faq) - [Getting Help with your Registration](https://help.opusdns.com/create-your-opusdns-account?hsLang=en#getting-help-with-your-registration) - [OpusDNS API](https://help.opusdns.com/opusdns-api?hsLang=en#main-content) - [Getting Started with the API](https://help.opusdns.com/opusdns-api?hsLang=en#getting-started-with-the-api) - [Sandbox Environment](https://help.opusdns.com/opusdns-api?hsLang=en#sandbox-environment) - [OpusDNS MCP Server](https://help.opusdns.com/opusdns-api?hsLang=en#opusdns-mcp-server) - [FAQ](https://help.opusdns.com/opusdns-api?hsLang=en#faq) - [Getting Help with the OpusDNS API](https://help.opusdns.com/opusdns-api?hsLang=en#getting-help-with-the-opusdns-api) - [OpusDNS Dashboard](https://help.opusdns.com/opusdns-dashboard?hsLang=en#main-content) - [Getting Started](https://help.opusdns.com/opusdns-dashboard?hsLang=en#getting-started) - [Plans & Pricing](https://help.opusdns.com/opusdns-dashboard?hsLang=en#plans-pricing) - [Billing & Payments](https://help.opusdns.com/opusdns-dashboard?hsLang=en#billing-payments) - [User & Organization Management](https://help.opusdns.com/opusdns-dashboard?hsLang=en#user-organization-management) - [Whitelabeling](https://help.opusdns.com/opusdns-dashboard?hsLang=en#whitelabeling) - [Account & Settings](https://help.opusdns.com/opusdns-dashboard?hsLang=en#account-settings) - [Security](https://help.opusdns.com/opusdns-dashboard?hsLang=en#security) - [Managing Contacts](https://help.opusdns.com/opusdns-dashboard?hsLang=en#managing-contacts) - [Managing DNS Zones & Nameservers](https://help.opusdns.com/opusdns-dashboard?hsLang=en#managing-dns-zones-nameservers) - [Register & Transfer Domains](https://help.opusdns.com/opusdns-dashboard?hsLang=en#register-transfer-domains) - [Managing Domains](https://help.opusdns.com/opusdns-dashboard?hsLang=en#managing-domains) - [Bulk Jobs](https://help.opusdns.com/opusdns-dashboard?hsLang=en#bulk-jobs) - [Developer Area](https://help.opusdns.com/opusdns-dashboard?hsLang=en#developer-area) - [Dashboard Functionality](https://help.opusdns.com/opusdns-dashboard?hsLang=en#dashboard-functionality) - [Dashboard home page](https://help.opusdns.com/opusdns-dashboard?hsLang=en#dashboard-home-page) - [Services & Features](https://help.opusdns.com/services-features?hsLang=en#main-content) - [Domain forwarding](https://help.opusdns.com/services-features?hsLang=en#domain-forwarding) - [Email forwarding](https://help.opusdns.com/services-features?hsLang=en#email-forwarding) - [Reports](https://help.opusdns.com/services-features?hsLang=en#reports) - [Domain parking](https://help.opusdns.com/services-features?hsLang=en#domain-parking) - [WHMCS Integration](https://help.opusdns.com/services-features?hsLang=en#whmcs-integration) - [Hostware Integration](https://help.opusdns.com/services-features?hsLang=en#hostware-integration) - [Terraform Integration](https://help.opusdns.com/services-features?hsLang=en#terraform-integration) - [GO Integraton](https://help.opusdns.com/services-features?hsLang=en#go-integraton) - [Certificate Management with ACME and OpusDNS](https://help.opusdns.com/services-features?hsLang=en#certificate-management-with-acme-and-opusdns) - [New to the Domain Industry?](https://help.opusdns.com/new-to-the-domain-industry?hsLang=en#main-content) - [Everything about Domains](https://help.opusdns.com/new-to-the-domain-industry?hsLang=en#everything-about-domains) - [Domain Industry](https://help.opusdns.com/new-to-the-domain-industry?hsLang=en#domain-industry) - [Reseller Essentials](https://help.opusdns.com/new-to-the-domain-industry?hsLang=en#reseller-essentials) - [TLD information](https://help.opusdns.com/tld-information?hsLang=en) - [OpusDNS Homepage](https://www.opusdns.com/) - [Legal Notice](https://www.opusdns.com/legal/notice-impressum) - [Privacy Policy](https://www.opusdns.com/legal/privacy-policy) - [Terms & Conditions](https://www.opusdns.com/legal/terms-conditions) [![OpusDNS Homepage](https://help.opusdns.com/hubfs/6722ae7333e645c8919a4751_opusDNS-VT-3c-white-tagline.svg "OpusDNS Homepage")](https://www.opusdns.com/) ©2025 OpusDNS GmbH.
