[*] Done without token

[OUARZA]

Describe the bug

I am trying to obtain the Google Home token using the helper Docker image mentioned in the documentation:

https://hub.docker.com/r/breph/ha-google-home_get-token

When I run the container and enter my Google account and app password, the script fails to retrieve both the master token and the access token.

Console output:

What is your google mail address? myaddress@gmail.com
What is the password or app password? ************

[*] Getting master token...
{'Error': 'BadAuthentication'}
[!] Could not get master token.
[*] Master token: None

[*] Getting access token...
{'Error': 'BadAuthentication'}
[!] Could not get access token.
[*] Access token: None

[*] Done.

Version: 0.7.6

I haven't been able to find a solution in the last four weeks to obtain a working master token. Today, I managed to get something using the OAuth token, but when I enter it in the configuration interface, I get the following error message: Invalid flow specified and Master token invalid. Make sure that the full token has been specified (including 'aas_et/').

I managed to get a mastertoken, but after a while it doesn't work anymore. All Google and Nest integrations in Home Assistant aren't available anymore. I'm completely fed up with Google and I'm going to phase out all the Google stuff like Doorcams, Smoke Detectors and Google Hubs. Even their own apps are buggy (Google Home and Nest). It's complete arrogance of Google. Sooner or later they will end up like Nokia with their phones in the early days of 2000.

Google Master Token — How I got it to work

Background

breph/ha-google-home_get-token (the Docker image commonly recommended) did not work.

• On the Pi (arm64): image is built for amd64 → exec format error
• On Windows via SSH: requires a real interactive TTY → does not work through a tunnel

The Solution — Python script with gpsoauth

Instead of the Docker image, we used a Python script with the gpsoauth library.

1. Install gpsoauth on the Pi

pip3 install gpsoauth --break-system-packages

2. Get the oauth_token via the browser

1. Open this URL in your browser and log in with your Google account:

   https://accounts.google.com/EmbeddedSetup
   

2. When the page shows "Success" or is blank — press F12
3. Go to the Application tab (Chrome) or Storage tab (Firefox)
4. Click Cookies → https://accounts.google.com
5. Find the cookie named oauth_token and copy its value (starts with oauth2_4/...)

3. Run the script on the Pi

import gpsoauth, json

EMAIL = "YOUR@GMAIL.COM"
ANDROID_ID = "0123456789abcdef"
oauth_token = "PASTE_YOUR_OAUTH_TOKEN_HERE"

master_response = gpsoauth.exchange_token(EMAIL, oauth_token, ANDROID_ID)

if 'Token' in master_response:
    print("Master Token:", master_response['Token'])
else:
    print("Failed:", json.dumps(master_response, indent=2))

python3 script.py

4. Result

The token starts with aas_et/... — that is your master token.

Thank you @tjelite1986, I finally got it working with your solution

This page isn't working. I log in and it just keeps looping. I don't have access to cookies.

Although the page staying in a constant loading state the oauth token is present in browser cookies. At least in my case it did.

Yes thats correct and needed to open it on a computer

I'm stupid, I didn't go to the right place :(

[OUARZA]

Are there no other ways to run the script? Can't it be done with Home Assistant?

Thats the only way i get it to work. :/ i did run it in a terminal but I have my ia do the work so idk.

[OUARZA]

And do you think it's possible to do something with Docker or LXC in my Proxmox?

I got it working in Docker on my PC.

@tjelite1986 Thanks!
Your instructions helped. I couldn't get the password in the Docker container. But using the script, it worked, though not the first time because I didn't insert the full OAth2 key.

Docker image not working:
[] Getting master token...
[!] Could not get master token.
[] Master token: None

[] Getting access token...
[!] Could not get access token.
[] Access token: None

[*] Done.

First, I've got a first key oath2 from browser cookies:

Next,
I ran the script:

root@guitar:/home/saddamko# python3 script.py
Master Token: aas_et/AKppINa.......

Script script.py was:

import gpsoauth, json

EMAIL = "mygoogleemail@GMAIL.COM"
ANDROID_ID = "0123336789abcdef"
oauth_token = "oauth2_4/0AeoW.......................................................VXg"

master_response = gpsoauth.exchange_token(EMAIL, oauth_token, ANDROID_ID)

if 'Token' in master_response:
    print("Master Token:", master_response['Token'])
else:
    print("Failed:", json.dumps(master_response, indent=2))
