Editor's Overview

SQRL Login is a security application developed by Daniel Persson, packaged as a single Android APK of version 1.7 weighing in at 4.36 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 4.36 MB, so it installs quickly even on modest connections.
This build is signed by "Daniel Persson" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

This app is an implementation for SQRL (Secure Quick Reliable Login) on Android.

Before you begin using SQRL to login to websites, your SQRL private identity
must be created. You only need one, probably for life, because it reveals
NOTHING about you, and it's highly secure. It's just a very long (77-digit)
random number.

From then on, whenever you login with SQRL to a website, your private identity
is used to generate another 77-digit number for that one website. Every website
you visit sees you as a different number, yet every time you return to the same
site, that site's unique number is regenerated.

This allows you to be uniquely and permanently identified, yet completely
anonymous.

Since you never need to use an eMail address or a password, you never give a
website your actual identity to protect. If the website's SQRL identities are
ever stolen, not only would the stolen identities only be valid for that one
website, but SQRL's cryptography prevents impersonation using stolen identities.

This is as good as it sounds. It's what we've been waiting for.

Frequently Asked Questions

Is SQRL Login free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does SQRL Login require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is SQRL Login safe to install?
We link to the exact APK published by Daniel Persson. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update SQRL Login?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
