# SQRL Login (open-source app)

> SQRL Login is a free, open-source app for Android. An implementation for SQRL (Secure Quick Reliable Login). It has 119 GitHub stars and is released under the MIT license, and you can install it from F-Droid and Google Play.

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.
