User authentication, made simple.
Stack Auth gives you everything you need to add secure logins, sign-ups, and user management to your website or app. Manage who can access what, set up social logins like Google, and control user permissions — all from one clean dashboard.
What makes Stack Auth worth launching.
Get beautiful sign-in and sign-up forms that work right out of the box, ready for your users.
See, search, edit, and manage all your users from one central place — no extra tools needed.
Let users sign in with Google, GitHub, or other accounts in one click instead of creating new passwords.
Create teams with their own permissions and invite members, perfect for B2B apps.
Decide exactly what each user or team can see and do with flexible permission settings.
Offer email, passwords, magic links, or passkeys — let your users choose what works best for them.
If you fit one of these, Stack Auth is probably built for you.
Practical scenarios where Stack Auth makes a real difference.
Add sign-ups and user accounts to your new software product in minutes instead of spending weeks building login systems.
Give different teams access to different parts of your app with custom permissions and organization structures.
Let users sign in with their existing Google or GitHub accounts instead of creating yet another password to remember.
Create a members-only area where users sign up and log in to access exclusive content, courses, or tools.
Stack Auth is an open-source authentication platform that handles the tricky business of user logins so you don't have to. With Stack Auth, you get pre-built sign-in and sign-up pages, a dashboard to manage all your users, and the ability to let people log in with Google, email, or magic links. You can create teams and organizations, set different permission levels, and even see who's doing what. It's everything you need to manage your users without building it from scratch.
Stack Auth is the authentication platform that saves you months of development work. Instead of building login pages, password resets, and permission systems from scratch, you get everything pre-built and ready to go. It's perfect for anyone launching a website or app that needs user accounts — whether you are a solo founder building your first product or a team managing hundreds of users.
