Passster – Password Protection



Passster makes password protecting your content easy.

Complete pages, posts, products(WooCommerce) or only parts of them with the integrated shortcode.

You can also use a modern and secure captcha solution instead of a password. Modern encryption keeps sure your passwords are incredibly secure.

You can use the following shortcode to partly password protect your content:
[passster password=»your-password»]your content[/passster]

You can also protect your content with a captcha:
[passster captcha=»true»]your content[/passster]


  • restrict complete pages/posts/products with a password
  • use a simple shortcode to protect parts of your content
  • ajax-driven unlock – no page reload required
  • modern and secure captcha with pure JavaScript
  • customise the style with the Customizer
  • use cookies to save access


  • use multiple passwords per page/post/product and shortcode
  • Google ReCaptcha v3 (invisible Captcha)
  • password lists for large sets of passwords
  • expire passwords after usage
  • protect Visual composer rows
  • auto-unlock content per user and user role

Paired with exceptional support directly from the developer, timely updates and feature integrations and extensive documentation you can’t go wrong with Passster Pro.

The free support is exclusively limited to the support forum.

Any kind of email priority support, customization and integration help need a valid premium license.


The plugin is coded with modern PHP and WordPress standards in mind. It’s fully OOP coded. It’s highly extendable for developers through several action and filter hooks.

Passster keeps your website performance in mind. Every script is loaded conditionally and all input and output data is secured.


All major texts and information can be modified from the admin area of Passster.

The plugin is fully translatable in your language. At the moment there are only en_EN and de_DE, but you can easily add your preferred language as a .po/.mo.

It’s also fully compatible with WPML and Polylang.

PASSSTER is a great plugin for any kind of password protection I can imagine. The free version already covers a wide range of use cases, at least the pro version fulfills any wishes and comes with a great developer-support (answers question within one day) on top. This is a clear 5-star-rating!

Well developed plugin with intuitive handling. Free version ist quite huge, but with pro version no cases for protecting your content remain unsatisfied! I will use it again in the future, for sure ... thanks for creating this one!

I downloaded the pro version of PASSSTER to create multiple passwords to my posts/pages, so different people can get special access to parts of my research project and I decide what they see and how long (expiration-option). This makes handling my publications so much easier and I work much more effective. Thanks Patrick for creating this plugin, it's simply perfect for my use case.

At the beginning I had some trouble using the customisation tabs, but with the support of Patrick I understand easily what I did wrong. All in all a very intuitive and simple to use plugin. It does exactly what it was created for ... The plugin fits my needs perfectly and combined with the excellent support this is a 5-star-rating! Thanks, Patrick.

The plugin is clear and simple. It does exactly what it is supposed to do. I had a problem with the password list, which Patrick solved immediately. Absolutely great support! Keep it up!

Basically this is a very nice and simple application to protect certain areas of a website with one or more passwords. Unfortunately, with each new update there are some difficulties with other plug-ins, possibly the theme, caching etc. After the last update a few days ago I got tired of it and solved the protection of certain areas differently and removed the plug-in. Actually a pity - but not like this.
