VoidAuth is a self-hosted Single Sign-On solution that aims to be easy to setup and use while feeling seamless to your users. Release v1.1.0 brings a few new features I have been working on and am excited about:

Passkey-only Users, the option on sign-up to use a passkey instead of a password.
Admin Notification Emails, so admins know when they have new tasks such as user registrations to approve.
Approval Emails for New Users, so new users awaiting approval know when they have been.
DEFAULT_REDIRECT back to your main page for invitations, logouts, etc.
and more!

Pretty much as answered already, passkeys (sometimes branded like FaceID or Windows Hello but it is an open spec) are an alternative to passwords. Your public key that identifies your user is stored in VoidAuth and your private key is stored on your device. Some password managers support syncing passkeys, so you don’t have to set up a new passkey on every device.

The advantage over passwords is that they are domain and device specific, so are much harder to be leaked from the client side. VoidAuth (or other services) should only be storing your public key so a leak on the server side would not allow someone to log in as you.
