Get tokens for Google Home Foyer API

Get tokens for Google Home Foyer API

Intro

This script (python 3) generates tokens that can be used when making requests to the Google Home Foyer API. There are 2 kinds of tokens used here:

  1. Master token - Is in the form aas_et/*** and is long lived. Needs Google username and password.
  2. Access token - Is in the form ya29.*** and lasts for an hour. Needs Master token to generate.

If you do not want to store the Google account password in plaintext, get the master token once, and set it as an override value.

It's safer/easier to generate an app password and use it instead of the actual password. It still has the same access as the regular password, but still better than using the real password while scripting. (https://myaccount.google.com/apppasswords)

Usage

thanks. will try that. was wondering if the inablity to pick up MAC address was an issue with this script or not.

This does not seem to be an error from glocaltokens. The call to getmac is an alias for a call to uuid.getnode and getnode is returning a value that is failing the check at line 48. This doesn't seem to involve any calls into glocaltokens.

I tried removing the check and and generating my own 48-bit integer, but I still fail to generate tokens.

Has this script worked for anyone else recently?

Error: AttributeError: module 'urllib3.util.ssl_' has no attribute 'DEFAULT_CIPHERS'

Fixed by downgrading urllib3 as per simon-weber/gpsoauth#52

Do not name your python file token.py this will create a circular import and the code wil not run!

Korben85 commented Jun 6, 2023

I tried downgrading and running the script but
pip install urllib3\<=2
installs the version 2.0.0 which also results in this error
I used
pip install urllib3\<2
instead to install urllib3-1.26.16
The script finishes w/o an error now.
I still got no master token, but that's not the fault of the script, I think.
However, I hope this helps someone else.

@thoompje, you can give a try getting master token using https://github.com/leikoilja/glocaltokens package. It does nearly the same as this gist, but has a few extra validation and logic around that might help you identify the issue

I couldn't get this to work in any version of Linux I had on hand, but I did finally get it to run in Windows.

This is what I did (in PowerShell 7.3.4 in Windows):

# make a new Python virtual environment
> python3 -m venv test123

# activate that environment
# ...the Windows way is like this:
> test123\Scripts\activate

# ...but the Linux way would be like this instead:
#> source test123/bin/activate

# install the bare minimum package list without declaring versions
> pip install gpsoauth

# then run the script
> python3 get_token.py

# ...and it failed with this error:
# AttributeError: module 'urllib3.util.ssl_' has no attribute 'DEFAULT_CIPHERS'

# so let's roll the urllib3 package back to whatever newest pre-2.0.0 version we can have...
> pip install urllib3<2.0.0

# and try again
> python3 get_token.py

# ...and then it succeeded!

Here's my version list:

> pip freeze

certifi==2023.5.7
charset-normalizer==3.1.0
gpsoauth==1.0.2
idna==3.4
pycryptodomex==3.18.0
requests==2.31.0
urllib3==1.26.16

Details that would help me if I need this info again:

  • My USERNAME variable had the @gmail.com omitted, so it was just the portion left of the @-symbol.
  • My PASSWORD variable was an Application-Specific Password (ASP), created at https://myaccount.google.com/apppasswords for the account.
  • The ASP was set as "custom" and I named it "Home" but I expect it will have worked no matter what it was named.
  • After failed tests in the script, the "Last used" timestamp was not populated for the ASP, as expected (it stayed set to -).
  • Immediately after the successful run, it immediately was updated to the current time (after a refresh of the ASP page to see that it occurred).
  • I don't think it is likely that Google was blocking the attempts, but simply that it was a version conflict of some kind that happened to work out with the Windows environment.
  • Python installed in this environment is Python 3.11.2 (tags/v3.11.2:878ead1, Feb 7 2023, 16:38:35) [MSC v.1934 64 bit (AMD64)] on win32, which looks like it was installed via winget install Python.Python.3.11
  • I did try https://github.com/leikoilja/glocaltokens in every environment except this Windows one, so it's possible it'll work in this one now, since this worked.

Thanks for taking the time to document this @emmaly . A question and two observations:

  • Did you intend to write instead 'python3 -m venv test123' in that first line? I am not sure what veth is in this context - I may be missing something.
  • I too have been unable to get this to perform correctly on Linix.
  • On Windows (and assuming you meant 'venv'), even after downgrading urllib3 as you did I still get the error AttributeError: module 'urllib3.util.ssl_' has no attribute 'DEFAULT_CIPHERS'. I assume there is something different about my environment but I have not yet worked out what it is.

ive tried this on my windows computer & live on the raspberry HA system.

always i get an "BadAuthentication",
On the https://myaccount.google.com/apppasswords page my app password is displayed (Called: "HomeAssistant") but it has never been retrieved, so apparently it fails already at the general call.

I have tested the following:
Username: my.email@gmail.com (Fake-Address)
Username: my.email (fake address)
Password: My real password
Password: My app password

I have played through all constellations, apparently the script fails directly on execution / before login.

Here are my examples, various constellations (commented out and censored)

# Creds to use when logging in
USERNAME = 'my.email@gmail.com'
#USERNAME = 'my.email'
#PASSWORD = 'mypassword_censored'
PASSWORD = 'my_apppassword'

Oops, yes, I did mean venv! I mistyped it here, but it was venv when it was done for real. Sorry about that. I've updated my comment that typo won't cause further confusion.

For sure, I never did get it to work in Linux for whatever reason.

Regarding the others... I forget the details. It's frustrating that it's not trivial to resolve!

It's related to the issue in gpsoauth simon-weber/gpsoauth#48 (comment)

Currently, it's only working on:

  • urllib3==1.26.16 with OpenSSL 1 working fine
  • urllib3-2.0.3 with OpenSSL 1 giving no attribute 'DEFAULT_CIPHERS'
  • urllib3==1.26.16 with OpenSSL 3 giving {'Error': 'BadAuthentication'}
  • urllib3-2.0.3 with OpenSSL 3 giving no attribute 'DEFAULT_CIPHERS'

Unfortunately, downgrading urllib is easy, but openssl not...

You can always check what you have by running the following:

$ dpkg --list | grep -e "openssl " -e "urllib3"
$ pip freeze | grep urllib

After a bunch of Googling and reading through comments I was able to get this to work via Docker with the following:

  1. Download get_tokens.py
  2. Update USERNAME to my full email
  3. Update PASSWORD to my app password
  4. Create Dockerfile:
    FROM python:3.9-slim-bullseye
    
    RUN pip install "urllib3<2.0.0" gpsoauth
    COPY ./get_tokens.py ./
    CMD python3 get_tokens.py
    
  5. Run docker build -t get_tokens . && docker run --rm -it get_tokens

Hopefully this should be fully reproducible by everyone.

Hi ,

how to do this step

Generated an App Password "gpsoauth"

Hopefully the App Password is the above one , i am not sure ?

I have an app password which I used for Password. It is not producing the access token. Below is the output

python3 get_tokens.py

This script generates tokens that can be used when making requests to the Google Home Foyer API.
There are 2 kinds of tokens used here:

  1. Master token - Is in the form aas_et/*** and is long lived. Needs Google username and password.
  2. Access token - Is in the form ya29.*** and lasts for an hour. Needs Master token to generate.
    If you do not want to store the Google account password in plaintext,
    get the master token once, and set it as an override value.
    It's safer/easier to generate an app password and use it instead of the actual password.
    It still has the same access as the regular password, but still better than using the real password while scripting.

same story as above, I cannot get the script to work. I also have passkeys enabled, I tried using both my actual password and two different application passwords just in case.

For anyone still facing an issue with this script, see this comment: leikoilja/ha-google-home#599 (comment)

Worked for me, first try.

I got the double whammy here: the app password copy/paste from the Google website does indeed contain hidden characters; after I retyped that I tried several scripts (in homeassistant's terminal) and must be hitting the library issue, so retyped in the dockerised script is the way to go.

The docker command in the main readme is slicker than the one in the comment linked above as it does it all on one line.

So thanks @Telmo and @Brephlas !
