How to lock particular customer account in Magento 2 [duplicate]

Question

I want to lock particular customer account in magento store. Any options to lock or blacklisted customer account using admin panel

Answer 1

Instead of making a module or having to recode anything, I did it through phpmyadmin. When you go in your files, go to customer_entity

Go to the customer that you want to LOCK out of their account. Click edit and go to the part that says

failures_num

and I typed 10 because max failed attempts is only 3. Go down to

lock_expires

and use the calendar to choose the year you want the lock to expire. You have to be within a reasonable time for it to accept the date, like 10 years from now. SAVE

Then go to customer_grid_flat go down to

lock_expires

and put the same date as you did the other file. SAVE

DONE

Now the customer can't log in until you unlock it. Which if you choose to, you can do in the admin panel under their customer info.

Answer 2

I don't think there is a way to do it from the admin panel, but you can set a value to the lock_expires field in the table customer_entity to a date really far in the future. This should lockout the customer.
