 ## 4. Authentication & IAM
 
+MyFSIO implements a comprehensive Identity and Access Management (IAM) system that controls who can access your buckets and what operations they can perform. The system supports both simple action-based permissions and AWS-compatible policy syntax.
+
+### Getting Started
+
 1. On first boot, `data/.myfsio.sys/config/iam.json` is seeded with `localadmin / localadmin` that has wildcard access.
 2. Sign into the UI using those credentials, then open **IAM**:
    - **Create user**: supply a display name and optional JSON inline policy array.

-The API expects every request to include `X-Access-Key` and `X-Secret-Key` headers. The UI persists them in the Flask session after login.
+### Authentication
+
+The API expects every request to include authentication headers. The UI persists them in the Flask session after login.
+
+| Header | Description |
+| --- | --- |
+| `X-Access-Key` | The user's access key identifier |
+| `X-Secret-Key` | The user's secret key for signing |
+
+**Security Features:**
+- **Lockout Protection**: After `AUTH_MAX_ATTEMPTS` (default: 5) failed login attempts, the account is locked for `AUTH_LOCKOUT_MINUTES` (default: 15 minutes).
+- **Session Management**: UI sessions remain valid for `SESSION_LIFETIME_DAYS` (default: 30 days).
+- **Hot Reload**: IAM configuration changes take effect immediately without restart.
+
+### Permission Model
+
+MyFSIO uses a two-layer permission model:
+
+1. **IAM User Policies** – Define what a user can do across the system (stored in `iam.json`)
+2. **Bucket Policies** – Define who can access a specific bucket (stored in `bucket_policies.json`)
+
+Both layers are evaluated for each request. A user must have permission in their IAM policy AND the bucket policy must allow the action (or have no explicit deny).

+| `*` (in actions) | All S3 actions | Grants `list`, `read`, `write`, `delete`, `share`, `policy`, `lifecycle`, `cors`, `replication` |
+| `iam:*` | All IAM actions | Grants all `iam:*` actions for user management |
+| `*` (in bucket) | All buckets | Policy applies to every bucket |
+
+### IAM Policy Structure
+
+User policies are stored as a JSON array of policy objects. Each object specifies a bucket and the allowed actions:
 
-**Full Control (admin):**
 ```json
-[{"bucket": "*", "actions": ["list", "read", "write", "delete", "share", "policy", "replication", "iam:*"]}]
+[
+  {
+    "bucket": "<bucket-name-or-wildcard>",
+    "actions": ["<action1>", "<action2>", ...]
+  }
+]
 ```
 
-**Read-Only:**
+**Fields:**
+- `bucket`: The bucket name (case-insensitive) or `*` for all buckets
+- `actions`: Array of action strings (simple names or AWS aliases)
+
+### Example User Policies
+
+**Full Administrator (complete system access):**
+```json
+[{"bucket": "*", "actions": ["list", "read", "write", "delete", "share", "policy", "lifecycle", "cors", "replication", "iam:*"]}]
+```
+
+**Read-Only User (browse and download only):**
 ```json
 [{"bucket": "*", "actions": ["list", "read"]}]
 ```
 
-**Single Bucket Access (no listing other buckets):**
+**Single Bucket Full Access (no access to other buckets):**
 ```json
-[{"bucket": "user-bucket", "actions": ["read", "write", "delete"]}]
+[{"bucket": "user-bucket", "actions": ["list", "read", "write", "delete"]}]
 ```
 
-**Bucket Access with Replication:**
+**Multiple Bucket Access (different permissions per bucket):**
 ```json
-[{"bucket": "my-bucket", "actions": ["list", "read", "write", "delete", "replication"]}]
+[
+  {"bucket": "public-data", "actions": ["list", "read"]},
+  {"bucket": "my-uploads", "actions": ["list", "read", "write", "delete"]},
+  {"bucket": "team-shared", "actions": ["list", "read", "write"]}
+]
 ```
 
+**IAM Manager (manage users but no data access):**
+```json
+[{"bucket": "*", "actions": ["iam:list_users", "iam:create_user", "iam:delete_user", "iam:rotate_key", "iam:update_policy"]}]
+```
+
+**Replication Operator (manage replication only):**
+```json
+[{"bucket": "*", "actions": ["list", "read", "replication"]}]
+```
+
+**Lifecycle Manager (configure object expiration):**
+```json
+[{"bucket": "*", "actions": ["list", "lifecycle"]}]
+```
+
+**CORS Administrator (configure cross-origin access):**
+```json
+[{"bucket": "*", "actions": ["cors"]}]
+```
+
+**Bucket Administrator (full bucket config, no IAM access):**
+```json
+[{"bucket": "my-bucket", "actions": ["list", "read", "write", "delete", "policy", "lifecycle", "cors"]}]
+```
+
+**Upload-Only User (write but cannot read back):**
+```json
+[{"bucket": "drop-box", "actions": ["write"]}]
+```
+
+**Backup Operator (read, list, and replicate):**
+```json
+[{"bucket": "*", "actions": ["list", "read", "replication"]}]
+```
+
+### Using AWS-Style Action Names
+
+You can use AWS S3 action names instead of simple names. They are automatically normalized:
+
+```json
+[
+  {
+    "bucket": "my-bucket",
+    "actions": [
+      "s3:ListBucket",
+      "s3:GetObject",
+      "s3:PutObject",
+      "s3:DeleteObject"
+    ]
+  }
+]
+```
+
+This is equivalent to:
+```json
+[{"bucket": "my-bucket", "actions": ["list", "read", "write", "delete"]}]
+```
+
+### Managing Users via API
+
+```bash
+# List all users (requires iam:list_users)
+curl http://localhost:5000/iam/users \
+  -H "X-Access-Key: ..." -H "X-Secret-Key: ..."
+
+# Create a new user (requires iam:create_user)
+curl -X POST http://localhost:5000/iam/users \
+  -H "Content-Type: application/json" \
+  -H "X-Access-Key: ..." -H "X-Secret-Key: ..." \
+  -d '{
+    "display_name": "New User",
+    "policies": [{"bucket": "*", "actions": ["list", "read"]}]
+  }'
+
+# Rotate user secret (requires iam:rotate_key)
+curl -X POST http://localhost:5000/iam/users/<access-key>/rotate \
+  -H "X-Access-Key: ..." -H "X-Secret-Key: ..."
+
+# Update user policies (requires iam:update_policy)
+curl -X PUT http://localhost:5000/iam/users/<access-key>/policies \
+  -H "Content-Type: application/json" \
+  -H "X-Access-Key: ..." -H "X-Secret-Key: ..." \
+  -d '[{"bucket": "*", "actions": ["list", "read", "write"]}]'
+
+# Delete a user (requires iam:delete_user)
+curl -X DELETE http://localhost:5000/iam/users/<access-key> \
+  -H "X-Access-Key: ..." -H "X-Secret-Key: ..."
+```
+
+### Permission Precedence
+
+When a request is made, permissions are evaluated in this order:
+
+1. **Authentication** – Verify the access key and secret key are valid
+2. **Lockout Check** – Ensure the account is not locked due to failed attempts
+3. **IAM Policy Check** – Verify the user has the required action for the target bucket
+4. **Bucket Policy Check** – If a bucket policy exists, verify it allows the action
+
+A request is allowed only if:
+- The IAM policy grants the action, AND
+- The bucket policy allows the action (or no bucket policy exists)
+
+### Common Permission Scenarios
+
+| Scenario | Required Actions |
+| --- | --- |
+| Browse bucket contents | `list` |
+| Download a file | `read` |
+| Upload a file | `write` |
+| Delete a file | `delete` |
+| Generate presigned URL (GET) | `read` |
+| Generate presigned URL (PUT) | `write` |
+| Generate presigned URL (DELETE) | `delete` |
+| Enable versioning | `write` (includes `s3:PutBucketVersioning`) |
+| View bucket policy | `policy` |
+| Modify bucket policy | `policy` |
+| Configure lifecycle rules | `lifecycle` |
+| View lifecycle rules | `lifecycle` |
+| Configure CORS | `cors` |
+| View CORS rules | `cors` |
+| Configure replication | `replication` (admin-only for creation) |
+| Pause/resume replication | `replication` |
+| Manage other users | `iam:*` or specific `iam:` actions |
+| Set bucket quotas | `iam:*` or `iam:list_users` (admin feature) |
+
+### Security Best Practices
+
+1. **Principle of Least Privilege** – Grant only the permissions users need
+2. **Avoid Wildcards** – Use specific bucket names instead of `*` when possible
+3. **Rotate Secrets Regularly** – Use the rotate key feature periodically
+4. **Separate Admin Accounts** – Don't use admin accounts for daily operations
+5. **Monitor Failed Logins** – Check logs for repeated authentication failures
+6. **Use Bucket Policies for Fine-Grained Control** – Combine with IAM for defense in depth
+
 ## 5. Bucket Policies & Presets
 
 - **Storage**: Policies are persisted in `data/.myfsio.sys/config/bucket_policies.json` under `{"policies": {"bucket": {...}}}`.
