Use Forgot password from the login popup. A single-use reset token is sent to the address on the account (in development the API returns it directly).
A password reset signs you out of every device holding that account — so after changing it, sign in fresh everywhere you play.
Reset tokens and verification links are single-use and expire; if yours is dead, request a fresh one.
If your account is suspended or you fail verification for a reason you do not understand, chat with us. Never share your password, client seed or 2FA codes with anyone — Ruble staff will never ask for them.
