Magento 2 Login as Customer Module

This repository contains a Login as Customer module that allows authorized Admin users to log in as customers from the Admin Panel with multi-website support and full audit traceability.

Key Features

• Multi-Website Support - Login as customer on any website (Ashokdubariya, Coverion, etc.)
• Smart Button Detection - Automatically shows single button or dropdown based on available websites
• Grid & Edit Page Access - Login from customer grid or edit page
• Cryptographically Secure - Token-based authentication with SHA-256 hashing
• Complete Audit Trail - Track every login attempt with full details
• ACL Protected - Granular permission control
• One-Time Tokens - Prevents replay attacks
• Configurable Expiry - Default 5-minute token lifetime

Security Features

• Cryptographically Secure Tokens - Uses random_bytes(32) for token generation
• SHA-256 Hash Storage - Tokens stored as hashes, never plaintext
• Single-Use Tokens - Automatically invalidated after first use
• Configurable Expiry - Default 5 minutes, prevents stale tokens
• ACL Protected - Dual permissions for login action and audit access
• Complete Audit Trail - Logs every attempt with admin/customer/IP/timestamp

Website Selection Logic

The module intelligently detects available websites:

• Global Customer Sharing (scope = 0): Shows all websites
• Per-Website Sharing (scope = 1): Shows only customer's assigned website
• Single Website: Simple button/action
• Multiple Websites: Dropdown button/multiple actions

Viewing Audit Log

1. Navigate to: Customers > Login as Customer
2. View grid with columns:
   • Log ID
   • Admin ID / Username
   • Customer ID / Email
   • IP Address
   • Status (Pending/Success/Expired/Failed)
   • Store View
   • Created At / Expires At / Used At
3. Use filters to search by admin, customer, status, date range

Security Considerations

What we do?

1. Token Generation: Cryptographically secure random_bytes(32) = 64 hex chars
2. Token Storage: Store SHA-256 hash only (64 chars), original token discarded after URL generation
3. Single-Use: Token status changed from pending → success after first use, subsequent attempts rejected
4. Expiration: Configurable TTL (default 5 min), server-side timestamp validation
5. Audit Logging: Every attempt logged with:
   • Admin ID/username
   • Customer ID/email
   • IP address
   • Timestamp
   • Outcome (success/failed/expired)
6. ACL Enforcement: Separate permissions for:
   • Performing login action
   • Viewing audit log
   • Modifying configuration
7. CSRF Protection: Magento's built-in form key validation on admin controllers
8. Session Regeneration: Customer session ID regenerated after login
9. No Password Exposure: Customer password hash never accessed

What we don't do?

• No customer password access
• No plaintext token storage
• No unlimited token lifetime
• No token reuse
• No bypass of ACL permissions
• No modification of customer data during login

Technical Details

1. Detects customer's primary website ID
2. Checks customer sharing configuration
3. Retrieves all accessible websites
4. Generates appropriate UI (single/multiple actions)
5. Passes website_id parameter to controller
6. Controller selects correct store based on website
7. Redirects to appropriate website base URL
