Looking for the name of the url of the identity page on ps1.6.1.3

[qcoupat]

Hello all,

I work on ps 1.6.1.3, I modified the order_conf file wich is the email the client receives when he makes a purchase.
I wanted to add a link to this page that gets him to his account/identity page, where he can modify his pswd, newsletter acceptance, etc.
I wanted to specify in the href the name of this page but cannot manage to find it... I found {history_url} that gets the client to its history. Would anyone know what is the name of this url to go to the identity page or would know where to find the information ?
Many thanks,
