This post on Web Tips 钩住一些选项操作和过滤器来修改密码强度限额，但评论者似乎对此有一些问题，所以对此持保留态度。

如果您无法使用挂钩路线，或者您有自定义登录页面，
this post on Tuts Plus 有一个方便的教程，可以在您自己的表单上使用现有脚本。
添加到functions.php:
wp_enqueue_script( \'password-strength-meter\' );
在HTML中：
<form>
<input type="password" name="password" />
<input type="password" name="password_retyped" />
<span id="password-strength"></span>
<input type="submit" disabled="disabled" value="Submit" />
</form>
脚本：
function checkPasswordStrength( $pass1,
$pass2,
$strengthResult,
$submitButton,
blacklistArray ) {
var pass1 = $pass1.val();
var pass2 = $pass2.val();
// Reset the form & meter
$submitButton.attr( \'disabled\', \'disabled\' );
$strengthResult.removeClass( \'short bad good strong\' );
// Extend our blacklist array with those from the inputs & site data
blacklistArray = blacklistArray.concat( wp.passwordStrength.userInputBlacklist() )
// Get the password strength
var strength = wp.passwordStrength.meter( pass1, blacklistArray, pass2 );
// Add the strength meter results
switch ( strength ) {
case 2:
$strengthResult.addClass( \'bad\' ).html( pwsL10n.bad );
break;
case 3:
$strengthResult.addClass( \'good\' ).html( pwsL10n.good );
break;
case 4:
$strengthResult.addClass( \'strong\' ).html( pwsL10n.strong );
break;
case 5:
$strengthResult.addClass( \'short\' ).html( pwsL10n.mismatch );
break;
default:
$strengthResult.addClass( \'short\' ).html( pwsL10n.short );
}
// The meter function returns a result even if pass2 is empty,
// enable only the submit button if the password is strong and
// both passwords are filled up
if ( 4 === strength && \'\' !== pass2.trim() ) {
$submitButton.removeAttr( \'disabled\' );
}
return strength;
}
jQuery( document ).ready( function( $ ) {
// Binding to trigger checkPasswordStrength
$( \'body\' ).on( \'keyup\', \'input[name=password1], input[name=password2]\',
function( event ) {
checkPasswordStrength(
$(\'input[name=password]\'), // First password field
$(\'input[name=password_retyped]\'), // Second password field
$(\'#password-strength\'), // Strength meter
$(\'input[type=submit]\'), // Submit button
[\'black\', \'listed\', \'word\'] // Blacklisted words
);
}
);
});
