We ❤️ open source. Your Tutanota client is fully published as open source software. 😍 We even built our own captcha instead of using Google's Captcha. Read here why: https://tutanota.com/blog/posts/open-source-email/
Why is this step necessary? mstdn.io might not be the server where you are registered, so we need to redirect you to your home server first.
