What are Custom Domains?

Custom Domains are an advanced feature that allows you to use your own domain name for Onetime Secret links, instead of the default onetimesecret.com domain. This feature adds a layer of branding and professionalism to your secret sharing activities, making it ideal for businesses and power users.

Key Benefits

  1. Enhanced Branding: Reinforce your company's identity by using your own domain for secret links.
  2. Increased Trust: Recipients see a familiar domain, boosting their confidence in the shared information.
  3. Seamless Integration: Create a cohesive experience that aligns with your existing digital presence.
  4. Professional Appearance: Demonstrate a higher level of sophistication and commitment to security.
  5. Potential Analytics: Leverage your domain's analytics tools for insights into usage patterns.
  6. Regional Flexibility: Choose between EU and US data center regions to meet your data locality needs.

Use Cases

Custom Domains are particularly valuable for:

  • Agencies: Share sensitive information with clients using branded links.
  • Financial Institutions: Securely communicate account details or transaction information.
  • Employee onboarding and training: Use custom domains to reinforce security best practices.
  • Legal Firms: Transmit confidential case information to clients or partners.
  • Healthcare Providers: Provide credentials to staff securely.
  • IT Departments: Distribute login credentials or system access information.
  • HR Teams: Communicate sensitive employee data or onboarding information.
  • Marketing Agencies: Share campaign strategies or client-specific data securely.
  • International Organizations: Choose the appropriate data center region for compliance with local regulations.

How Custom Domains Work

  1. You register a domain or use one you already own.
  2. Choose your preferred data center region (EU or US).
  3. Configure your domain's DNS settings to point to Onetime Secret's servers in your chosen region.
  4. Set up the custom domain in your Onetime Secret account settings.
  5. Once verified, your secret links will use your custom domain.

Important Considerations
