1Password

chezmoi includes support for 1Password using the 1Password CLI to expose data as a template function.

Log in and get a session using:

op account add --address $SUBDOMAIN.1password.com --email $EMAIL
eval $(op signin --account $SUBDOMAIN)

This is not necessary if you are using biometric authentication.

The output of op read $URL is available as the onepasswordRead template function, for example:

{{ onepasswordRead "op://app-prod/db/password" }}

returns the output of

op read op://app-prod/db/password

Documents can be retrieved with:

{{- onepasswordDocument "$UUID" -}}

The output of op item get $UUID --format json is available as the onepassword template function. chezmoi parses the JSON output and returns it as structured data. For example, if the output is:

{
  "id": "$UUID",
  "title": "$TITLE",
  "version": 2,
  "vault": {
    "id": "$vaultUUID"
  },
  "category": "LOGIN",
  "last_edited_by": "$userUUID",
  "created_at": "2010-08-23T13:18:43Z",
  "updated_at": "2014-07-20T04:40:11Z",
  "fields": [
    {
      "id": "username",
      "type": "STRING",
      "purpose": "USERNAME",
      "label": "username",
      "value": "$USERNAME"
    },
    {
      "id": "password",
      "type": "CONCEALED",
      "purpose": "PASSWORD",
      "label": "password",
      "value": "$PASSWORD",
      "password_details": {
        "strength": "FANTASTIC",
        "history": []
      }
    }
  ],
  "urls": [
    {
      "primary": true,
      "href": "$URL"
    }
  ]
}

Then you can access the password field with the syntax

{{ (index (onepassword "$UUID").fields 1).value }}

or:

{{ range (onepassword "$UUID").fields -}}
{{   if and (eq .label "password") (eq .purpose "PASSWORD") -}}
{{     .value -}}
{{   end -}}
{{ end }}

onepasswordDetailsFields returns a reworked version of the structure that allows the fields to be queried by key:

{
  "password": {
    "id": "password",
    "label": "password",
    "password_details": {
      "history": [],
      "strength": "FANTASTIC"
    },
    "purpose": "PASSWORD",
    "type": "CONCEALED",
    "value": "$PASSWORD"
  },
  "username": {
    "id": "username",
    "label": "username",
    "purpose": "USERNAME",
    "type": "STRING",
    "value": "$USERNAME"
  }
}

{{- (onepasswordDetailsFields "$UUID").password.value }}

Additional fields may be obtained with onepasswordItemFields; not all objects in 1Password have item fields. This can be tested with:

chezmoi execute-template "{{ onepasswordItemFields \"$UUID\" | toJson }}" | jq .

Sign-in prompt

chezmoi will verify the availability and validity of a session token in the current environment. If it is missing or expired, you will be interactively prompted to sign-in again.

In the past chezmoi used to exit with an error when no valid session was available. If you'd like to restore this behavior, set the onepassword.prompt configuration variable to false, for example:

~/.config/chezmoi/chezmoi.toml

[onepassword]
    prompt = false

Danger

Do not use prompt on shared machines. A session token verified or acquired interactively will be passed to the 1Password CLI through a command line parameter, which is visible to other users of the same system.

Secrets Automation

chezmoi has experimental support for secrets automation with 1Password Connect and 1Password Service Accounts. These might be used on restricted machines where you cannot or do not wish to install a full 1Password desktop application.

When these features are used, the behavior of the 1Password CLI changes, so chezmoi requires explicit configuration for either connect or service account modes using the onepassword.mode configuration option. The default, if not specified, is account:

~/.config/chezmoi/chezmoi.toml

[onepassword]
    mode = "account"

In account mode, chezmoi will stop with an error if the environment variable OP_SERVICE_ACCOUNT_TOKEN is set, or if both environment variables OP_CONNECT_HOST and OP_CONNECT_TOKEN are set.

Info

Both 1Password Connect and Service Accounts prevent the CLI from working with multiple accounts. If you need access to secrets from more than one 1Password account, do not use these features with chezmoi.

1Password Connect

Once 1Password Connect is configured, and OP_CONNECT_HOST and OP_CONNECT_TOKEN are properly set, set onepassword.mode to connect.

~/.config/chezmoi/chezmoi.toml

[onepassword]
    mode = "connect"

In connect mode:

• the onepasswordDocument template function is not available,
• account parameters are not allowed in 1Password template functions,
• chezmoi will stop with an error if one or both of OP_CONNECT_HOST and OP_CONNECT_TOKEN are unset, or if OP_SERVICE_ACCOUNT_TOKEN is set.

1Password Service Accounts

Once a 1Password service account has been created and OP_SERVICE_ACCOUNT_TOKEN is properly set, set onepassword.mode to service.

~/.config/chezmoi/chezmoi.toml

[onepassword]
    mode = "service"

In service mode:

• account parameters are not allowed in 1Password template functions,
• chezmoi will stop with an error if OP_SERVICE_ACCOUNT_TOKEN is unset, or if both of OP_CONNECT_HOST and OP_CONNECT_TOKEN are set.
