This guide is designed to help builders quickly and effectively communicate the secure access method for invited subcontractors on E1.
The One-Time Code (OTC) is E1's secure default access method for invited subcontractors who choose not to create or log in to an E1 account. It ensures project security while providing a low-friction way for them to access your tender documents and submit quotes.
1. How to Explain the One-Time Code to your Subcontractors
The key message to your subcontractors is that the One-Time Code is a simple, secure step to protect confidential project information.
| For Subcontractors who: | How to Access the Project: | Main Benefits: |
|---|---|---|
| Do not have an E1 account (or choose not to log in) | They must use the One-Time Code (OTC). | Security and Simplicity: It's a quick, secure verification for access to confidential tender documents and submitting quotes. |
| Do have an E1 account | They can log in directly to their E1 account. | Efficiency: No code needed. Centralised tender management, profile-building, and more work opportunities. |
Why the One-Time Code is required (Security & Compliance)
The One-Time Code is a critical security measure that protects the integrity of your tendering process and the confidentiality of your project data:
- Verifies Identity: It ensures that only the intended recipient (the person invited to quote) can view confidential documents and drawings, and perform commercially sensitive actions like submitting a quote.
- Best Practice Security: It's a method similar to two-factor authentication used by financial and government services.
- 30-Day Access: Once a subcontractor successfully enters a code, they are verified for that specific browser/device for 30 days. They will not need to re-enter a code for any other E1 invitations from any builder within that period.
2. Quick Instructions to share with Subcontractors
If a subcontractor contacts you about trouble accessing the project, you can share these simple steps with them:
Subcontractor Steps to Use the One-Time Code:
- Click the button or link in the invitation email to access the project documentation.
- On the page that opens, choose the option to get a one-time code (if you don't want to log in). Do not close this page.
- A code will be sent to the original email recipient of the invitation. Check your main inbox, as well as Spam or other folders.
- Copy or remember the code, go back to the E1 page, and submit it. That's it!
- Tip: The verification lasts for 30 days on that device, so you won't need to do this again for any other E1 invitations from any builder for a month.
3. Directions to the Subcontractor Help Centre
For detailed, step-by-step guidance, please direct your subcontractors to the official E1 Subcontractor Help Centre (it’s different to the builder-facing help centre).
