# Users & permissions
|

## Auth scenarios
|
|
|
|
| Scenario | Auth | Ownership / visibility |
|
|
| -------- | ---- | ---------------------- |
|
|
| Web upload | Session cookie | Current user |
|
|
| API upload + **user token** | `Auth-Token` header | Token owner |
|
|
| API upload + **global token** | `Auth-Token` header | Admin (`userId` null) |
|
|
| Twikoo `POST /api/index.php` | form `token` | Same as global token |
|
|
| Gallery list / search / delete | Session or token | Users: own only; admin: all |
|
|
| Direct link `GET /images/...` | None (Referer rules) | Public if URL is known |
|
|
|
|
## Accounts
|
|
|
|
- By default only admins create users; **allow registration** is an admin setting
|
|
- Passwords hashed with scrypt
|
|
- Web login requires a slider captcha (align the thumb with the gap)
|
|
- Login rate limiting
|
|
|
|
## Upload preferences & auto-delete
|
|
|
|
- **Upload preferences** (home card flip): client compression, auto-copy links, per user
|
|
- **Auto-delete**: global (admin) and per-user policies; affects **new uploads after enable** only
|
|
|
|
## API tokens
|
|
|
|
| Type | Managed by | Upload owner | Typical use |
|
|
| ---- | ---------- | ------------ | ----------- |
|
|
| **Global** | Admin (API page) | Admin account | Twikoo, site-wide scripts |
|
|
| **Personal** | Each user (API page) | That user | Personal blog, private scripts |
|
|
|
|
`API_UPLOAD_TOKEN` in env locks the global token — see [Environment variables](./configuration.md).
