We’re (fx.gl) using it in all our games to create a connection between game account and email. It works great. User click on mail to link. Send email with uniq token. Sever receives email and connection is created.

Some caveats:

1. not everyone has email set up on phone. We provide instructions to send email by hand.

2. We emphasize for user to choose correct email if they using work and personal email. No good solution here if user connect game account to work email. Only letter to support
