Before you start
You need:- An activation email from
support@realtimelca.comwith the subject Activate your Real-Time LCA user. - Access to the inbox the email was sent to.
If you cannot find the email, check your spam folder. If it still does not appear, reach out to support@realtimelca.com and we will resend the invite.
Step 1: Open the activation email
Open the Activate your Real-Time LCA user email and click Activate your user. If the button does not work, copy the link below it and paste it into your browser.
Step 2: Choose how to activate
The activation link takes you to Activate your account. You can either set a Real-Time LCA password or activate with your Microsoft account.
- Set a password
- Use Microsoft
- Enter a password in New password.
- Re-enter the same password in Confirm new password.
- Click Activate.
Step 3: Meet the password requirements
As you type, each requirement turns green when satisfied. Your password must contain:- At least 8 characters
- At least 1 number
- At least 1 special character
- At least 1 lowercase letter
- At least 1 capital letter
- No 3 or more recurring characters

Step 4: Confirm activation
When activation succeeds you see a confirmation screen, and the browser redirects to the Real-Time LCA app shortly after.
A second email: your Speckle credentials
Alongside activation, Real-Time LCA automatically provisions a Speckle user for you on our own Speckle server and sends a follow-up email with the server URL and a temporary password. You only need this if you plan to connect a design authoring tool (Revit, Rhino, ArchiCAD, Grasshopper) to Real-Time LCA — otherwise you can ignore it. See Introduction to Speckle for the install steps and how the connection fits together.Next steps
