Storing passwords — vdirsyncer 0.16.8 documentation

# Storing passwords

Changed in version 0.7.0: Password configuration got completely overhauled.

Vdirsyncer can fetch passwords from several sources other than the config file.

## Command

Say you have the following configuration:

    [storage foo]
    type = "caldav"
    url = ...
    username = "foo"
    password = "bar"

But it bugs you that the password is stored in cleartext in the config file. You can do this:

    [storage foo]
    type = "caldav"
    url = ...
    username = "foo"
    password.fetch = ["command", "~/get-password.sh", "more", "args"]

You can fetch the username as well:

    [storage foo]
    type = "caldav"
    url = ...
    username.fetch = ["command", "~/get-username.sh"]
    password.fetch = ["command", "~/get-password.sh"]

Or really any kind of parameter in a storage section.

With pass for example, you might find yourself writing something like this in your configuration file:

    password.fetch = ["command", "pass", "caldav"]

### Accessing the system keyring

As shown above, you can use the `command` strategy to fetch your credentials from arbitrary sources. A very common usecase is to fetch your password from the system keyring.

The keyring Python package contains a command-line utility for fetching passwords from the OS’s password store. Installation:

    pip install keyring

Basic usage:

    password.fetch = ["command", "keyring", "get", "example.com", "foouser"]

## Password Prompt

You can also simply prompt for the password:

    [storage foo]
    type = "caldav"
    username = "myusername"
    password.fetch = ["prompt", "Password for CalDAV"]
