FusionAuth 1.5 adds passwordless login and more. Download and upgrade now!


Published: March 28, 2019

Logging in without a password? In what fantasy land can that be secure?!? The fact is it can be much more secure than traditional passwords, and is now supported in our newest release. FusionAuth 1.5 is now available for direct download, FastPath one-line install, Homebrew or Docker. It includes new features, a few changes, and minor fixes for issues discovered by QA testers and our growing community of users. Get the brief overview below, and visit our release notes for the full details.

New Feature - Passwordless Login

For years, one of the most common ways hackers use to access servers, data, and accounts has been to guess, steal, phish, or otherwise obtain the username and password of an authorized user. Unfortunately selecting, changing, updating, remembering, and managing passwords for the multiple accounts that most people have these days has become a monumental task of its own, and too many people end up ignoring safe password guidelines, leading to more hacking and more data breaches.

So why don’t we get rid of passwords altogether? Ok, good idea. Done.

Login with a magic link.

The FusionAuth 1.5 release now allows passwordless login via user email, providing a secure way to authenticate users without complex password r3qu!r3mENt5 that nobody can remember. Users simply type in their email address and get a secure email with a link back to the site. When they click the link, they are authenticated and can enter the site or application without issue. If a malicious user tries to login with your email address, they’ll never see the email, and won’t be able to get gain access.

In case passwordless is brand new to you, this concept isn’t something we just invented. It’s been used by Microsoft in Outlook, Office, Skype, and Xbox Live. Passwordless is also a keystone technology of WebAuthn recommended by the World Wide Web Consortium (w3c) and supported by all major browsers.

If you’re still not getting it, read more about passwordless here. As passwords continue to be proven difficult to secure, more sites and applications will rely on passwordless authentication solutions in one form or another.

Why isn’t it used by everyone already?

Because change is hard and many applications that store user credentials were not built with this type of flexibility in mind. This is why we added it to FusionAuth. We specialize in removing pain from authentication so that every site and application can take advantage of the ever evolving methods of authentication.

Fixes & Updates

While we are pretty excited about passwordless login, the FusionAuth 1.5 release has many other updates and fixes that you should know about. Here are just a few to get you started, and visit our release notes for the full details.

  • Added support for the OAuth2 / OpenID Connect Implicit Grant. See the OAuth 2.0 & OpenID Connect Overview and OAuth 2.0 Endpoints for additional information.
  • OAuth2 grants can now be enabled or disabled per application.
  • Change Password API can be called using a JWT providing additional support for the Change Password workflow in a single page web application.
  • The Change Password API can return a One Time password (OTP) allowing for a more seamless user experience when performing a change password workflow.
  • When using the Change Password workflow the user will be automatically logged in upon completing the change password required during login.
  • We improved the Two Factor Login API to provide additional support and ease of use in a single page web application.
  • We adjusted the workflow when a user has 2FA enabled and a password change is required during login. Now the 2FA will occur before the change password workflow.
  • The id_token is now signed with the client_secret when HS256, HS384 or HS512 is selected as the signing algorithm. This is necessary for compliance with OpenID Connect Core ID Token Validation. This fixes Github Issue #57. Thanks to anbraten for reporting this issue.
  • A change to the Docker build for permissions reduced the overall FusionAuth app image by ~200 MB.
