In general, you should have received an email after getting registered for the trial or purchasing Blog2Social Premium.
You should have received your license key with your welcome email, together with the login credentials.

If you already have the login credentials you can log into your Blog2Social account at https://service.blog2social.com/en/login/ anytime to get your license key or change your account data whenever needed.
