Description
As a WordPress owner who values both security and a seamless user experience, you often face the challenge of protecting sensitive information. Most password solutions force your visitors to register for an account, granting them potential access to your WordPress environment.
This is where „OTP Content Protect“ comes in, offering an innovative way to protect your content with a One-Time Password (OTP).
Our plugin was designed to give you full control over your content without opening the doors to your WordPress backend for strangers. Easily and effectively protect individual posts, pages, or even downloads. Your visitors don’t need an account and don’t have to register—they simply enter the one-time password you provide and get instant access.
By not granting unnecessary backend access, you actively minimize the risk of hacker or spam activities. „OTP Content Protect“ is the perfect blend of simplicity, security, and innovation, making it the ideal password protection for your WordPress site when you need to lock specific content without burdening users with registration.

Installation
- Unzip and upload the
otp-content-protectfolder to your/wp-content/plugins/directory. Alternatively, find and install it directly via the „Add New“ plugin screen. - Activate the plugin through the ‘Plugins’ menu in WordPress.
- Navigate to Settings OTP Protect to configure and generate OTPs.
FAQ
-
Do users need to register to view the content?
-
No, and that is the plugin’s main advantage. A user only needs to enter the one-time password you provide. No WordPress user account is required.
-
How can I allow an OTP to be used more than once?
-
In the admin overview, you can edit any used OTP and reset it with a single click. This clears the usage timestamp and makes the password immediately valid again.
-
Is plugin data removed on uninstall?
-
Yes. When you delete the plugin from the WordPress admin area, the included
uninstall.phpfile ensures the associated database table (<prefix>_otpcp_protect) is cleanly removed. -
Can multiple passwords be active for the same post?
-
Yes. You can create multiple different and simultaneously active OTPs for the same piece of content. Each one will be validated correctly upon entry.
