do you have another passwor for your Behance Login? Here - in any case - the link to "Adobe ID, sign-in, and account help" http://helpx.adobe.com/x-productkb/policy-pricing/account-password-sign-faq.html where you can get the answer, I believe.

If you have a login questions - please contact Behance support directly. Behance is transitioning all logins to Adobe IDs this Spring 2014. If you signed up for Behance post April 10, 2014, your Behance login matches your Adobe ID exactly. If you signed up before this and are having trouble logging in, visit this section for more help, or contact Behance support. Please do not comment on this forum with login questions, as we're able to provide much faster, one-on-one support elsewhere.
please control "or contact Behance Support". There is no link.
