# Mass Deployment
Breadcrumbs are volatile and need slightly more upkeep than Tokens and Canaries themselves. They are relatively short-lived, lasting only until the Canary's settings (or IP) changes. Depending on what was changed, new breadcrumbs may need to be generated and deployed.
To make this easier for you, Breadcrumbs can be mass deployed by making use of breadcrumb-deploy Flock API auth keys that can only be used on Breadcrumb endpoints. This allows you to build them into your automation and deployment scripts.
Breadcrumb-deploy Flock API keys can be generated via the "Flock API Key endpoints" and setting auth_token_type to breadcrumb-deploy.
WARNING
While breadcrumb-deploy Flock API auth keys limit visibility of Canary details to the contents of the chosen Breadcrumb, it is recommended that they be disabled after they are used by scripts to deploy breadcrumbs. This can be done via the "Remove Flock API key" endpoint.
