add Line login at third party login

Hello everyone.

When providing a login method for the younger generation in Japan, I believe that being able to use LINE Login will lower the hurdle considerably. This is because the younger generation in Japan usually uses LINE messages rather than email applications for communication, so they are not logged out on a daily basis.
"Of LINE's 95 million monthly users, 86% (as of the end of June 2023) use LINE at least once a day, a high usage rate. The highest frequency of use is among males in the 20-24 age group and females in the 25-29 age group."

This is why I am clamoring for line login to be available on supabase auth.

Thanks.

LINE login is an extremely popular login method in Japan. Please consider it as it would significantly contribute to the adoption of Supabase in Japan.

Hi, I am desperately longing for this feature. Could you escalate this to the team to add it to the roadmap? I believe you can convince them how important LINE login is to Japanese users.

been trying to hack to integrate with line login for 2 days (LIFF). not found proper solution. So I moved whole supabase-related snippet to server-side (but I believe supabase sdk was designed with client-side in mind...)

There is a separate discussion for consolidating what providers we support here: supabase/auth#451 (comment)

If you want Supabase to add support for something, go ahead and vote over there. I'm going to close this one so that people will actually go to the correct one.
