Every day, botnets carry out brute force attacks against thousands of WordPress sites and blogs, regardless of size. Once inside, botnets infect your visitors with malware. A compromised website leads to delisting by search engines or blocking by your hosting provider. Rublon prevents such attacks and protects your accounts.

"Thanks to Rublon, two-factor authentication for WordPress is now easy and we have no problem convincing our customers to use two-factor authentication."

Rublon rocks

Instant, increased security for your website

Rublon is the only two-factor authentication solution that works out-of-the-box. No software installation required. Rublon instantly increases security for protected accounts in a natural way, via email or phone.

No one-time passwords

Traditional two-factor authentication solutions demand users enter a one-time password each time they want to login. That’s why people don’t like them. Rublon is different. With Rublon, you confirm your identity by simply clicking on a link or scanning a Rublon Code.

No training or configuration needed

We made increased security easy. Because Rublon’s default communication channel is email, users don’t need training. Identity confirmation via email is familiar, comfortable and widely used. Rublon is pre-configured for WordPress, with no set-up tutorials to wade through. Rublon works out-of-the-box.

Recognizes trusted devices

Your Rublon is linked to trusted devices - your desktops, laptops, phones and tablets. With Rublon, all you need to access your account on a trusted device is your password. And, if you sign in to several WordPress websites on a trusted device, you only authenticate once.

Compatible with all web browsers and operating systems

Each Rublon update is rigorously tested with all major web browsers (Chrome, Firefox, Internet Explorer, Opera and Safari) and operating systems (Linux, OS X, Windows). High compatibility matters to us because it matters to you - your coworkers and clients preferred environments.

All connections secured by TLS/SSL

Our Secure Socket Layer (SSL) certificate means all connections from Rublon to your server or any user account are encrypted by default. We use encryption whenever possible to ensure you the highest standard of security.

Optional mobile app for more security

Want more than identity confirmation via email? If you want a security solution that uses your phone for successful authentication, download the Rublon mobile app. Read more!

Fantastic support

Our community is eager to help you at any time. For premium users, our dedicated support team is available 24/7 and ready to answer questions and help with any issues.

Remote logout

Forgot to logout on a computer? We've got you covered. Rublon lets you log out remotely. Just remove a trusted device using any other of your trusted devices saved in Rublon.

Passwordless login (coming soon)

Tired of entering your password each time you want to log in? Rublon allows you to login by entering your username and simply confirming your identity via Rublon.

Business features

If you run a business and want to protect more than one account per website or need advanced features, we offer a paid Business Edition that meets your needs. Besides an unlimited number of protected accounts, the Business Edition also includes:

Enforceable to all or selected user groups

Select and enforce a minimum protection level for user groups. With a membership site, for example, you may want to require members to confirm their identity using the mobile app. This step cuts down on shared login credentials that give access to people who aren’t paying for your service.

Account changes require manual confirmation

Imagine someone got access to your account because you logged in on a public WiFi network or you left your computer unattended. If someone tries to lock you out by changing your password or email address, Rublon protects you. Password and email changes require confirmation from you via email or our mobile app.

Multi-user administration

The Access Control Manager allows multiple employees to use one shared WordPress administrative account. Once access is shared, identified users can access your account from their devices. Traditional two-factor authentication solutions make such collaboration very difficult. Rublon makes it easy.

More Great Features

Mobile App for More Security and Control

Authentication based on cryptographic keys

The Rublon mobile app uses asymmetric cryptography to ensure a high level of security. During setup, a private key is generated that never leaves your phone. The public key gets sent to Rublon, which makes it possible to confirm your identity by scanning a randomly generated Rublon Code.

Remote management of trusted devices

Rublon maintains a list of your trusted devices at all times, anywhere you are. The Rublon mobile app also allows you to remove them remotely, which logs you out of all your protected accounts (coming soon).

Phone based, out-of-band authentication

Because your phone typically uses a web connection different from what your computer uses, the Rublon mobile app allows you to take advantage of out-of-band authentication.

Use of the Access Control Manager

The Rublon mobile app allows you to give employees access to your account using your login credentials through the Access Control Manager. Employees will be able to access your account from their trusted devices.

More happy — and secure
