This page shows you how to install yagmail and how to set it up to use your system keyring service.

Installing from PyPI

The usual way of installing yagmail is through PyPI. It is recommended to install it together with the keyring library, by running the following (for Python 2.x and 3.x respectively):

pip install yagmail[all]
pip3 install yagmail[all]

If installing yagmail with keyring causes issues, omit the [all] to install it without.

Installing from GitHub

If you’re not scared of things occasionally breaking, you can also install directly from the GitHub repository. You can do this by running the following (for Python 2.x and 3.x respectively):

pip install -e git+[all]
pip3 install -e git+[all]

Just like with the PyPI installation method, if installing with keyring causes issues, simply omit the [all] to install yagmail without it.

Configuring Credentials

While it’s possible to put the username and password for your E-Mail address into your script, yagmail enables you to omit both. Quoting from keyrings README:

What is Python keyring lib?

The Python keyring lib provides a easy way to access the system
keyring service from python. It can be used in any
application that needs safe password storage.

If this sparked your interest, set up a Python interpreter and run the following to register your GMail credentials with yagmail:

import yagmail
yagmail.register('mygmailusername', 'mygmailpassword')

(this is just a wrapper for keyring.set_password('yagmail', 'mygmailusername', 'mygmailpassword')) Now, instantiating yagmail.SMTP is as easy as doing:

yag = yagmail.SMTP('mygmailusername')

If you want to also omit your username, you can create a .yagmail file in your home folder, containing just your username. Then, you can instantiate the SMTP client without passing any arguments.

Using OAuth2

Another fairly safe method for authenticating using OAuth2, since you can revoke the rights of tokens. In order to use OAuth2, pass the location of the credentials file to yagmail.SMTP:

yag = yagmail.SMTP('', oauth2_file='~/oauth2_creds.json')

If the file could not be found, then it will prompt for a google_client_id and google_client_secret. You can obtain these on this OAauth2 Guide, upon which the OAauth2 code of yagmail is heavily based. After you have provided these, a link will be shown in the terminal that you should follow to obtain a google_refresh_token. Paste this again, and you’re set up!

If somebody obtains the file, they can send E-Mails, but nothing else. As soon as you notice, you can simply disable the token.
