Sign In & Authentication

Rekhic offers frictionless entry: you can use the product anonymously as a guest without creating an account, or authenticate for cloud persistence and multi-device access.

1. Anonymous Guest Mode

When you first open Rekhic, you are granted immediate access as an Anonymous Guest:

• No email, password, or registration required.
• A randomized guest identifier (guestUserId) is generated locally.
• All diagrams, nodes, and configurations are saved strictly to your browser's local IndexedDB.
• Privacy: No diagram data is transmitted to or stored on remote cloud servers during guest usage.

[!WARNING] If you clear your browser cookies and site storage while in guest mode, your local diagrams will be permanently removed. To safeguard your diagrams, consider creating an account.

2. Creating a Registered Account

To enable cloud backup and access your workspaces across multiple computers:

1. Click Sign In in the top navigation bar.
2. Choose one of two authentication methods:
   • Google OAuth: Fast 1-click sign-in using your Google account.
   • Email and Password: Sign up with your work or personal email address.

3. Automatic Guest Workspace Migration

If you draft diagrams as a guest and then sign in to a permanent account:

• Rekhic automatically detects your local guest diagrams.
• It safely associates and migrates them to your authenticated user account.
• Your local diagrams are uploaded to Firebase Firestore cloud storage so they are immediately accessible on other devices.
• You never lose diagrams created during guest drafting sessions.
