# Sessions
Use one default runtime session and optional named persistence:
```bash
# Show current runtime session
agent-browser session
# Output: default
# Show active daemon sessions
agent-browser session list
```
## Session isolation
The runtime session is fixed to `default`. Use `--session-name` to isolate persisted state files per workflow.
- Cookies and storage snapshots
- Authentication state
- Saved state lifecycle
## Session persistence
Use `--session-name` to automatically save and restore cookies and localStorage across browser restarts:
```bash
# Auto-save/load state for "twitter" session
agent-browser --session-name twitter open twitter.com
# Login once, then state persists automatically
agent-browser --session-name twitter click "#login"
# Or via environment variable
export AGENT_BROWSER_SESSION_NAME=twitter
agent-browser open twitter.com
```
If `--session-name` is omitted, it defaults to `default`.
State files are stored in `~/.agent-browser/sessions/` and automatically loaded on daemon start.
### Session name rules
Session names must contain only alphanumeric characters, hyphens, and underscores:
```bash
# Valid session names
agent-browser --session-name my-project open example.com
agent-browser --session-name test_session_v2 open example.com
# Invalid (will be rejected)
agent-browser --session-name "../bad" open example.com # path traversal
agent-browser --session-name "my session" open example.com # spaces
agent-browser --session-name "foo/bar" open example.com # slashes
```
## State encryption
Encrypt saved state files (cookies, localStorage) using AES-256-GCM:
```bash
# Generate a 256-bit key (64 hex characters)
openssl rand -hex 32
# Set the encryption key
export AGENT_BROWSER_ENCRYPTION_KEY=<your-64-char-hex-key>
# State files are now encrypted automatically
agent-browser --session-name secure-session open example.com
# List states shows encryption status
agent-browser state list
```
## State auto-expiration
Automatically delete old state files to prevent accumulation:
```bash
# Set expiration (default: 30 days)
export AGENT_BROWSER_STATE_EXPIRE_DAYS=7
# Manually clean old states
agent-browser state clean --older-than 7
```
## State management commands
```bash
# List all saved states
agent-browser state list
# Show state summary (cookies, origins, domains)
agent-browser state show my-session-default.json
# Rename a state file
agent-browser state rename old-name new-name
# Clear states for a specific session name
agent-browser state clear my-session
# Clear all saved states
agent-browser state clear --all
# Manual save/load (for custom paths)
agent-browser state save ./backup.json
agent-browser state load ./backup.json
```
## Authenticated sessions
Use `--headers` to set HTTP headers for a specific origin:
```bash
# Headers scoped to api.example.com only
agent-browser open api.example.com --headers '{"Authorization": "Bearer <token>"}'
# Requests to api.example.com include the auth header
agent-browser snapshot -i --json
agent-browser click @e2
# Navigate to another domain - headers NOT sent
agent-browser open other-site.com
```
Useful for:
- **Skipping login flows** - Authenticate via headers
- **Switching users** - Different auth tokens per session
- **API testing** - Access protected endpoints
- **Security** - Headers scoped to origin, not leaked
## Multiple origins
```bash
agent-browser open api.example.com --headers '{"Authorization": "Bearer token1"}'
agent-browser open api.acme.com --headers '{"Authorization": "Bearer token2"}'
```
## Global headers
For headers on all domains:
```bash
agent-browser set headers '{"X-Custom-Header": "value"}'
```
