instead of your custom code
preg_match(‘/[^-0-9A-Za-z _.@] and so on

The trick I’ve used to create a user is as follows:
‘user_nicename’ => ‘tmp’.round(microtime(true))

This way user always gets created and then populated with correct values with:
$wpdb->query(“UPDATE $wpu_db_utab SET user_login

Can you please show how nicename is set in the process of user creation by w3all
I just want to set is as username without alterations and it would be nice to use it a display name too

Thnx for all your good work.
Some WP plugins, like Allow Cyrillic Usernames enable additional chars to be used in username.
What they do is add filter on the sanitize_user hook and add more chars.

As far as I can see, in the fix you enforce those chars, so even less ppl can SSO now:)
That’s for the default WP install, but not WP with plugins, or am I wrong?

Btw, you sanitize_user with strict = false and WP does it with strict = true AFAIK.

I think even changing username to something like user13223 is better not logging them in.
