Google Family Link integration

This was the hurdle I came up against, and eventually gave up… I couldn’t figure out how to ensure the cookie was valid and also implement something that would refresh in the background without needing a prompt for auth.

Hi @5AMsan
Could you share details of the API calls you could detect to the APIs ?
I made some tests but was not able to detect this calls.
Thanks

That’s indeed the missing point. Using a trusted browser can help but for how long ? At some point Google will ask for auth and we won’t be able to automate this part IMHO

Is there a way to find out how long the auth lasts? For me I’d gladly accept some kinda manual reauth weekly if it means I don’t have to open the Family Link app every day.

I’m wondering if it’s worth looking at how badnest handles this for inspiration because that uses cookie auth for Google logins

What’s Badnest’s project? Maybe something like this one?

That’s it, see line 187.

I’m not sure if Family Link could work in a similar fashion.
