Did you already share the location of a device with the account you added for this component?
yes with my friend… another error

I just upgraded to 0.68.1 and decided to give Google Maps Device Tracker a whirl. I followed the install directions on: Google Maps - Home Assistant
HA Version: 0.68.1
HA Install: Hass.io
Server: RaspberriPi 3
Config:
device_tracker: platform: google_maps username: !secret google_maps_login password: !secret google_maps_password
Setup:
Sharing my location with a new account. Attempting to login to new account from HA. Not using 2FA.
After restarting, I got this error:
Response: [None, None, ‘0ahUKEwjFvuai9uTaAhWP0YMKHawNAhAQ8ZABCAE’, ‘h5ToWoXfAo-jjwSsm4iAAQ’, None, None, ‘CP+potcFEAAaAA==’, 1800, 1525191815054, None, None, [0]]

I checked the unknown device security check as explained in the install directions, and verified with Google that it was infact me trying to login.
Restarted HA and got this error:

I deleted the .google_maps_location_sharing.cookies file. Restarted and get the first error again. Restarted… then got the second error again.
I checked the other tread, and didn’t see any help there.
Please Help!
@gremblin I to just upgraded to 68.1, PI3, hassio.
Exact same steps and I to am getting the line 211 error, invaldCookies(message).
Please post if you figure it out.
Ok from having dived around the threads, I’ve done this to get it to work:
This process worked for me, but YMMV.
Hi all
thanks for sharing this feature.
Can this be done to locate multiple users, for example all my family shares locations with a new account (as far as I understood, each one should share with a new account)?
Thanks
I get to approve my login on my phone, but i dont see it show up under Device Activity on the Google Page and i cant approve a login there either ( there is no prompt for it ).
Are you using 2FA aswell on your gmail account?
Thanks
I’ve been trying to get this working too. If I delete the cookie file and restart HA, the message The cookies provided do not provide a valid session.Please authenticate normally and save a valid session again goes away and I see a message pop up on my phone to verify that the user trying to log in is me. Once I approve the log in, the known_devices.yaml file still doesn’t get created. I see a ring on my map but it doesn’t update.
According to Device tracker - Home Assistant
Once device_tracker is enabled, a file will be created in your config dir named known_devices.yaml. Edit this file to adjust which devices to be tracked.
How do I get this file to be created using google_maps device tracker?
I see this message in my log files:
ERROR (SyncWorker_12) [locationsharinglib.Service] Could not open pickle file, either file does not exist or no read access.#033[0m
Any idea what that means?
EDIT:
Never mind, I found this post and followed it’s recommendation. I created a fresh google account (without 2-step security) and I think that solved the problem. Now my known_devices.yaml file gets created with the necessary location data. 
Has anyone found their already existing known_devices.yaml not being appended with the device tracker entry from this component?
Both the .cookies file and known_devices.yaml have rw-r–r-- and the latter gets appended normally from other components.
And no error in the log either so I am at a loss.
Same thing here.
Hey @toddsantoro. I got the device tracker going. What I did wrong was twhen sharing my main acct location with the dummy acct, the maps app glitched on me and I thought the process was complete but it wasn’t. I went into the app again and when I tapped the empty avatar of the dummy acct in “Location sharing” a card popped up with a toggle to activate sharing my location with that acct. Restarted HA and there it was! known_devices was recently modified!
I hope that is your issue too, please let me know how it went for you.
This worked for me too. The instructions on the component page are not clear. They state that you only need to have the dummy account follow you and not that both need to be following each other. I also deleted the /config/.google_maps_location_sharing.cookies file which still shows 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte but I now have the device showing up.
On another note have you gotten the step counter in Own Tracks to work?
My dummy account doesn’t follow anyone.
Weird… I had to follow myself and then it magically worked after hassio restart. I think I am going to go unfollow myself.
Actually I’m confused. I never had the dummy account share with anyone. The setup process is really confusing. I guess I finally just clicked the right stuff by mistake…
Yeah, my dummy didn’t need to reciprocate the sharing either, just activate that damned toggle that din’t show up on screen the first time around
I’m having similar issues getting this working. Here are my steps:
The .google_maps_location_sharing.cookies file was created in /config, but all I got from HA was the error “Could not open pickle file, either file does not exist or no read access.”. No traceback, no nothing.
According to the Device Activity page on my dummy account HA has not even attempted to log in. Nothing has appeared in the Device Activity page and there is nothing pending approval. No entries are appended to my known_devices.yaml.
Any thoughts?
