Hi guys,  I'd like to move from BigCommerce but cannot ask my current customers to create logins/signup again. Is there a way to export logins credentials so my customers would use the same password on my new Shopify website? Thanks in advance!

Did you have logins and passwords for your customers? If yes, were you able to export them so customers would not need to signup again?

what do you mean? can you please rephrase this.
