Description

SQRL can be used to log in to a site in a secure manner without giving away any personal information. This plugin enables that functionallity.

Instead of using a username, email and a password, SQRL uses an app to login to SQRL-aware websites.

When SQRL logs you into a website, your identity is a long code that looks like this: E6Qs2gX7W-Pwi9Y3KAmbkuYjLSWXCtKyBcymWloHAuo.

Your SQRL identity is a different long code for every website you login to, but it is always the same code when you return to a site you visited before. This means that websites never know who you are, but they do know when you return.

You may choose to remain anonymous to a website, such as when you post a response to someone’s blog. SQRL never identifies you by anything other than that long code.

In other cases you will want to be known, like when you use SQRL to login as you at Amazon, Facebook, Netflix, or your bank. In those cases, you would inform Amazon that that particular code is actually you. SQRL lets you do that.

Special thanks to:

@davidshimjs (Sangmin, Shim) for writing a great javascript library for QRCode creation. (https://github.com/davidshimjs/qrcodejs)
@jaredatch (Jared Atchison) for writing a plugin for disabling users that I took inspiration from. (https://github.com/jaredatch/Disable-Users)

Does what it says it will do and for that you gotta love it -- and offer up major props to the author. Thanks! Still, it wasn't immediately apparent to me that you needed to link WP users with their SQRL identities. I know, I know...but still that's one of those things that's only obvious _after_ you realize it. Otherwise, it's tough on newbies trying SQRL on their first attempt. Nothing that couldn't be fixed by a FAQ on wordpress.org.

After activating the plugin and visiting the Users > Your Profile page, I scanned the QR code at the bottom and was good to go. Beautiful work, Daniel!

This is possibly the most significant WP plugin to drop on the net. No - it is NOT PERFECT, but for users with concerns about MITM, eavesdropping, and maintaining control of their IDs, as well as site admins that care about maintaining privacy of their users, this is a game-changer. This plugin is a work-in-progress and as such, is undergoing active development and not all features may be yet implemented when you first get this. As a method to uniquely identify a website user while maintaining the users privacy during login, it works. As this is a security plugin, all server environment requirements must be met to ensure proper functionality ty. And as this plugin is still developing, it is ALMOST feature-complete per the sQRL:// protocol. This CANNOT BE OVERSTATED: You MUST download an SQRL app to create an identity BEFORE you can use this plugin for authentication. You MUST write down, print, or export the RECOVERY CODE shown right after create by identity. THERE IS NO ONE WHO CAN HELP YOU TO RECOVER A FORGOTTEN PASSWORD. As a website operator, you MIGHT require user to have an existing account with a verified email address prior to allowing users to login with SQRL. Since this is a TOTALLY DIFFERENT way of loggin-in than most users will be used to - expect a learning curve. But rest assured that once it is understood and properly used, it is friction-free.

A SQRL Plugin that just works! Daniel is making a great effort on brilliant Plugin, it worked for me straight away. I have it installed on two different websites on different servers and it is working well.

In a matter of a few days this plugin has gone from experimental to excellent. SQRL is going to be an important authentication system and is by far and away my favourite method already.

Thank you for making this excellent SQRL login plugin! It works great! One suggestion is it took a bit to discover that I needed to go to my wordpress profile to associate my SQRL identity to my WordPress admin account. Perhaps making a "Settings" link on the plugin page would help this.
