How to fix the error "The minimum password length is 6" when creating an account in Magento
On some Magento installations you may get this error:
The minimum password length is 6
when creating a new customer account even though you are using a password longer than 6 characters. To fix this issue, you need to change the iconv.internal_encoding PHP value in your PHP configuration to UTF-8. You can do this by adding the following line to your php.ini file:
iconv.internal_encoding = UTF-8
Once you change the iconv.internal_encoding to UTF-8, the error message will no longer show and your users will be able to create new accounts without any problems.
