Key - Manage repository keys

The key command allows you to set multiple access keys or passwords per repository. In fact, you can use the list, add, remove, and passwd (changes a password) sub-commands to manage these keys very precisely:

    $ rustic key list
    enter password for repository:
    | ID        | User     | Host    | Created                              |
    |-----------|----------|---------|--------------------------------------|
    | *8a9d4286 | username | kasimir | 2025-08-12 13:29:57.759858440 +02:00 |

    $ rustic key add --with-created --username alex --hostname batman
    enter password for new key: [hidden]
