+# Authentication Patterns
+
+Patterns for handling login flows, session persistence, and authenticated browsing.
+
+## Basic Login Flow
+
+```bash
+# Navigate to login page
+agent-browser open https://app.example.com/login
+agent-browser wait --load networkidle
+
+# Get form elements
+agent-browser snapshot -i
+# Output: @e1 [input type="email"], @e2 [input type="password"], @e3 [button] "Sign In"
+
+# Fill credentials
+agent-browser fill @e1 "user@example.com"
+agent-browser fill @e2 "password123"
+
+# Submit
+agent-browser click @e3
+agent-browser wait --load networkidle
+
+# Verify login succeeded
+agent-browser get url  # Should be dashboard, not login
+```
+
+## Saving Authentication State
+
+After logging in, save state for reuse:
+
+```bash
+# Login first (see above)
+agent-browser open https://app.example.com/login
+agent-browser snapshot -i
+agent-browser fill @e1 "user@example.com"
+agent-browser fill @e2 "password123"
+agent-browser click @e3
+agent-browser wait --url "**/dashboard"
+
+# Save authenticated state
+agent-browser state save ./auth-state.json
+```
+
+## Restoring Authentication
+
+Skip login by loading saved state:
+
+```bash
+# Load saved auth state
+agent-browser state load ./auth-state.json
+
+# Navigate directly to protected page
+agent-browser open https://app.example.com/dashboard
+
+# Verify authenticated
+agent-browser snapshot -i
+```
+
+## OAuth / SSO Flows
+
+For OAuth redirects:
+
+```bash
+# Start OAuth flow
+agent-browser open https://app.example.com/auth/google
+
+# Handle redirects automatically
+agent-browser wait --url "**/accounts.google.com**"
+agent-browser snapshot -i
+
+# Fill Google credentials
+agent-browser fill @e1 "user@gmail.com"
+agent-browser click @e2  # Next button
+agent-browser wait 2000
+agent-browser snapshot -i
+agent-browser fill @e3 "password"
+agent-browser click @e4  # Sign in
+
+# Wait for redirect back
+agent-browser wait --url "**/app.example.com**"
+agent-browser state save ./oauth-state.json
+```
+
+## Two-Factor Authentication
+
+Handle 2FA with manual intervention:
+
+```bash
+# Login with credentials
+agent-browser open https://app.example.com/login --headed  # Show browser
+agent-browser snapshot -i
+agent-browser fill @e1 "user@example.com"
+agent-browser fill @e2 "password123"
+agent-browser click @e3
+
+# Wait for user to complete 2FA manually
+echo "Complete 2FA in the browser window..."
+agent-browser wait --url "**/dashboard" --timeout 120000
+
+# Save state after 2FA
+agent-browser state save ./2fa-state.json
+```
+
+## HTTP Basic Auth
+
+For sites using HTTP Basic Authentication:
+
+```bash
+# Set credentials before navigation
+agent-browser set credentials username password
+
+# Navigate to protected resource
+agent-browser open https://protected.example.com/api
+```
+
+## Cookie-Based Auth
+
+Manually set authentication cookies:
+
+```bash
+# Set auth cookie
+agent-browser cookies set session_token "abc123xyz"
+
+# Navigate to protected page
+agent-browser open https://app.example.com/dashboard
+```
+
+## Token Refresh Handling
+
+For sessions with expiring tokens:
+
+```bash
+#!/bin/bash
+# Wrapper that handles token refresh
+
+STATE_FILE="./auth-state.json"
+
+# Try loading existing state
+if [[ -f "$STATE_FILE" ]]; then
+    agent-browser state load "$STATE_FILE"
+    agent-browser open https://app.example.com/dashboard
+
+    # Check if session is still valid
+    URL=$(agent-browser get url)
+    if [[ "$URL" == *"/login"* ]]; then
+        echo "Session expired, re-authenticating..."
+        # Perform fresh login
+        agent-browser snapshot -i
+        agent-browser fill @e1 "$USERNAME"
+        agent-browser fill @e2 "$PASSWORD"
+        agent-browser click @e3
+        agent-browser wait --url "**/dashboard"
+        agent-browser state save "$STATE_FILE"
+    fi
+else
+    # First-time login
+    agent-browser open https://app.example.com/login
+    # ... login flow ...
+fi
+```
+
+## Security Best Practices
+
+1. **Never commit state files** - They contain session tokens
+   ```bash
+   echo "*.auth-state.json" >> .gitignore
+   ```
+
+2. **Use environment variables for credentials**
+   ```bash
+   agent-browser fill @e1 "$APP_USERNAME"
+   agent-browser fill @e2 "$APP_PASSWORD"
+   ```
+
+3. **Clean up after automation**
+   ```bash
+   agent-browser cookies clear
+   rm -f ./auth-state.json
+   ```
+
+4. **Use short-lived sessions for CI/CD**
+   ```bash
+   # Don't persist state in CI
+   agent-browser open https://app.example.com/login
+   # ... login and perform actions ...
+   agent-browser close  # Session ends, nothing persisted
+   ```
