[TYPO3-dev] fe_users - where to find confirmation code?

[DirkHo]

Hi all,

I want to check if a frontend user confirmed his registration (made with 
sr_feuser_register) and was enabled by a backend user.

I couldn't find any table containing the value sent via email as part of 
the confirmation link. Or how's that handled?

Could you please tell me which table I have to (left) join from fe_users 
table or how I can identify user not having confirmed their email 
address, yet?

Thanks and kind regards,

Dirk
