# Token security

| [Domain whitelisting](/setup/security/token-security/domain-whitelisting.md) | Specify which domains your Cloudimage token can download original images from. You can limit the list to a few domains that you own to make sure no one uses your token on his or her URLs. |
| ---------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [URL signature](/setup/security/token-security/url-signature.md)             | Sign your Cloudimage URLs with an SHA hash to prevent someone else from using your Cloudimage token.                                                                                        |
| [URL sealing](/setup/security/token-security/url-sealing.md)                 | With this feature, you can sign only part of the url which will allow you to add more parameters to the URL while protecting the sealed ones.                                               |
