Access code email to Internal Canditates with TCC

Content

Dear Experts,

For Smart org user account there is a seperate operation of "send login Info" is available in TCC to send email with access code to users.

Similarly for Internal Candidate account,

-->is there any TCC operations to send Access code directly to users?

-->Any Possibility of sync between smartorg user account and Internal Candidate account(mean same password for both Internal CS and Smartorg user account).

Regards,
Vakas.
