### ✅ Testing
- [ ] All Playwright tests pass
- [ ] Unit tests for auth components pass
- [ ] Integration tests with Supabase work
- [ ] Role-based access control tested
- [ ] Session management tested
- [ ] API authentication tested

### ✅ Configuration
- [ ] Environment variables are set correctly
- [ ] Supabase configuration is verified

### ✅ Migration
- [ ] Old auth files are identified for removal
- [ ] Import statements are updated
- [ ] Component usage is migrated
- [ ] API client usage is migrated
- [ ] Backup of old system is created

## Deployment Steps

### 1. Staging Deployment

- [ ] Run full test suite
- [ ] Test login/logout flow
- [ ] Test session persistence
- [ ] Test role-based access
- [ ] Test API authentication
- [ ] Test error handling
- [ ] Performance testing

### 2. Production Deployment
- [ ] Deploy to production
- [ ] Monitor error logs
- [ ] Test critical user flows
- [ ] Monitor session management
- [ ] Check API performance

- [ ] Test password reset flow

## Rollback Plan

### If Issues Occur
1. [ ] Identify the specific issue

3. [ ] Review error logs
4. [ ] If critical, prepare rollback
5. [ ] Communicate with team
6. [ ] Execute rollback if needed
7. [ ] Document lessons learned

### Rollback Steps
1. [ ] Restore old auth files from backup
2. [ ] Update import statements
3. [ ] Revert component changes
4. [ ] Revert API client changes
5. [ ] Test old system functionality
6. [ ] Notify users of temporary changes
7. [ ] Plan fix for new system
