If you are an Administrator, Author, Editorial Board member, new subscriber (via a society or personal). Then a dormant SpringerLink account has been automatically created for your email address. When this happens a new account activation email is sent to your registered email address. In this email is an activation link to activate your account. Please check if you have received this email (it may have ended up in your SPAM/junk mail folder). If the original email was not received or otherwise is lost/missing then please contact us at: onlineservice@springernature.com  and we will send you a new one.
