<p>With WP-OTP you can easily set up 2 Factor Authentication with One Time Passwords for your WordPress login.<br />
This extra layer makes your WordPress site a lot more secure.</p>
<p>The new stealth mode allows for invisible OTP code entry, making your login screen look like any other, no extra OTP code input field.</p>
<h4>Getting started</h4>
<p>After installing and activating the plugin, every user can enable WP-OTP on their profile page.</p>
<p>It’s as easy as scanning the provided QR Code or entering the OTP secret to any OTP generator app.<br />
Then just activate it by entering the generated OTP and voilà, all set up.<br />
Now, the login requires an OTP code to succeed.</p>
<p>Each user gets their own secret key to authenticate with, giving them control over their login security.</p>
