Hi @pirralhobat,

It took me a minute to grasp onto what you were reporting, but I finally got it. What we’re seeing here is expected behavior and doesn’t actually require the first 2 steps you documented with screenshots.

The reason this is happening is a combination of three settings:

• Allow customers to create an account on the “My account” page
• When creating an account, automatically generate an account username for the customer based on their name, surname or email
• When creating an account, automatically generate an account password

Disabling just one of the following will “fix” the problem you’re not wanting to see:

• Allow customers to create an account on the “My account” page
• When creating an account, automatically generate an account password

Either a) you won’t be allowing your customers to register via the My Account page, or b) you won’t be auto-generating a password during that registration (requiring your customers to enter their own password).

If any of this doesn’t make sense, please let me know!

The problem was indeed one of interpretation of the configurations.

I ended up disabling the “When creating an account, automatically generate an account password” and adding code to make email validation, so that users who used the website in the past to make purchases are validated. This ends up blocking any user that tries to create accounts with emails previously used to make purchases.
