There used to be exactly one way in: email, password, confirmation letter. Three steps before a person even sees the world they came for.
VK ID and Yandex ID — two taps, no password, no letters
Telegram and Discord — switched on as well, but invisible from Russia: signing in through foreign services is banned by law, not by us
Takes you back — after signing in you stay on the same page instead of landing on the home screen
Works from inside worlds — you can sign in straight from a roleplay's own address, without hopping to the main domain
Your old account stands — email sign-in is still there, and a channel links to it in settings
Someone who opened a role's page in a stranger's world now presses one button and stays right there — instead of working out where the login threw them.
