Magento has the feature to verify the authenticity of newly registered customers before activating their account.
When a user registers to your Magento shop, then he/she will get a confirmation email with a confirmation link. The customer’s account will be activated only after he/she clicks that confirmation link.
By default this feature is not activated in Magento. Here is a step-by-step guide to activate this feature in Magento:-
– Go to System -> Configuration -> CUSTOMERS -> Customer Configuration
– Click Create New Account Options
– Set Require Emails Confirmation = Yes
– Save Config
Now, whenever a user registers to your Magento shop, he/she will get a confirmation email with a confirmation link. The customer’s account will be activated only after he/she clicks that link.
Hope it helps. Thanks.
