if ( ! empty( $user->user_pass ) && strlen( $user->user_pass ) < $wpide_min_password_length ) {
$errors->add( 'pass', sprintf( '<strong>Error:</strong> Passwords must be at least %d characters long.', $wpide_min_password_length ) );

add_action( 'validate_password_reset', function ( $errors ) use ( $wpide_min_password_length ) {
$password = isset( $_POST['pass1'] ) && is_string( $_POST['pass1'] ) ? wp_unslash( $_POST['pass1'] ) : '';
if ( '' !== $password && strlen( $password ) < $wpide_min_password_length ) {
$errors->add( 'pass', sprintf( '<strong>Error:</strong> Passwords must be at least %d characters long.', $wpide_min_password_length ) );

Change 12 to your preferred minimum. WooCommerce account forms use their own strength meter.
