Changing customer id and using the newly assigned as login instead of email address

[williambesson]

Hello,

 

For synchronization reasons with another system I would need to assign the number I want as customer id. Do you think this is possible?

 

If yes would it be possible to use this new customer id as login instead of the email address?

(If that means never using any email notifications afterwards for the customer that's absolutely fine).

 

Many thanks for your help on this.
