Customers or Users login to the website or mobile app using their phone number or email id. Both phone number and email id uniquely identify a single customer. So no two customers can have the same email id or phone number.
However, a customer's email id or phone number can be updated as long as the above mentioned uniqueness criteria is maintained. To update the email id or phone number of the user :
1. Login to the admin console
2. Go to the "User Management" console
3. Search for the user using the existing email id or phone number
4. Click on the "Edit User" icon in the "Action" column.
- The tooltip on the action buttons should make it clear
5. Input the new email id or the phone number
6. Click on the "Update" button.
If the newly provided email id or the phone number do not adhere to the above mentioned uniqueness criteria you will be shown an error. If the uniqueness criteria is satisfied the User record will be updated. After the update customer can login using the new email id or phone number.
Few points to note :
1. After the email id or phone number is updated, all subsequent communication, like transaction emails or text messages (SMS) will go to the updated email id or phone number.
2. Updating the email id or phone number from the User Management console does NOT require a password change.
3. Updating the email id or phone number from the User Management console will NOT automatically logout an user if they have already logged in to the app or website using the old login. However if they manually logout, the next time when they want to login they will have to use the updated email id or phone number.
