# Your sync code

> Write this code down. It restores your sightings on any other device. Anyone with the code can read your list, so keep it to yourself.

## Restore on this device

Enter the code from your other device. Your local ticks stay; the two lists merge.

The code has the form `AC-XXXX-XXXX-XXXX-XXXX`. It is the only credential and it is anonymous: no email address, no password, no profile.

An agent uses a code only when the person supplied it. It never creates one unasked and never prints one.

API: `POST https://animalchecklist.com/api/v1/accounts`, `GET|PUT https://animalchecklist.com/api/v1/sightings` with `Authorization: Bearer <code>`.
