Synopsis

Adds or removes SSH authorized keys for particular user accounts.

Parameters

Parameter	Choices/Defaults	Comments
comment string		Change the comment on the public key. Rewriting the comment is useful in cases such as fetching it from GitHub or GitLab. If no comment is specified, the existing comment will be kept.
exclusive boolean	Choices: no ← yes	Whether to remove all other non-specified keys from the authorized_keys file. Multiple keys can be specified in a single `key` string value by separating them by newlines. This option is not loop aware, so if you use `with_` , it will be exclusive per iteration of the loop. If you want multiple keys in the file you need to pass them all to `key` in a single batch as mentioned above.
follow boolean	Choices: no ← yes	Follow path symlink instead of replacing it.
key string / required		The SSH public key(s), as a string or (since Ansible 1.9) url (https://github.com/username.keys).
key_options string		A string of ssh key options to be prepended to the key in the authorized_keys file.
manage_dir boolean	Choices: no yes ←	Whether this module should manage the directory of the authorized key file. If set to `yes`, the module will create the directory, as well as set the owner and permissions of an existing directory. Be sure to set `manage_dir=no` if you are using an alternate directory for authorized_keys, as set with `path`, since you could lock yourself out of SSH access. See the example below.
path path		Alternate path to the authorized_keys file. When unset, this value defaults to ~/.ssh/authorized_keys.
state string	Choices: absent present ←	Whether the given key (with the given key_options) should or should not be in the file.
user string / required		The username on the remote host whose authorized_keys file will be modified.
validate_certs boolean	Choices: no yes ←	This only applies if using a https url as the source of the keys. If set to `no`, the SSL certificates will not be validated. This should only set to `no` used on personally controlled sites using self-signed certificates as it avoids verifying the source site. Prior to 2.1 the code worked as if this was set to `yes`.

    user: charlie
    state: present
    key: "{{ lookup('file', '/home/charlie/.ssh/id_rsa.pub') }}"
    path: /etc/ssh/authorized_keys/charlie
    manage_dir: False

- name: Set up multiple authorized keys

- name: Set authorized key without validating the TLS/SSL certificates
  ansible.posix.authorized_key:
    user: charlie
    state: present
    key: https://github.com/user.keys
    validate_certs: False

- name: Set authorized key, removing all the authorized keys already set
  ansible.posix.authorized_key:
    user: root
    key: "{{ lookup('file', 'public_keys/doe-jane') }}"
    state: present
    exclusive: True

- name: Set authorized key for user ubuntu copying it from current user
  ansible.posix.authorized_key:
