Here is what I checked. For the same stake login, this
link from Stake Access lets you verify a listed mirror before entering your existing account details. A legitimate mirror should route you to the same Stake account, wallet, history, and security settings. Never send a password, authenticator code, backup code, or recovery link to someone in chat. If you already submitted data to a doubtful form, change the password through a verified route and secure the connected email. Keeping one account is safer and usually required by platform rules, so do not solve access issues with duplicates.
