# Open Signup

With Open Signup you can create a link that lets anyone register and gain access to your apps. This is especially useful when you don't have a defined list of users who should have access to the app.

## Enable Open Signup

The Open Signup feature is per app, so you will need to enable it on each app where you want users to be able to sign up.

1. Go to the app where you want to enable Open Signup
2. Click **Manage Users**
3. Click **User Settings**
4. Check **Enable Open Signup**
5. Click **Save**
6. Share the URL of the app registration page to anyone you want. The URL will be in the form of workspace.stackerhq.com/app-name/register.

For apps updated from Stacker Classic, new users will need to go to the same url as your current user login, for example appname.my.stacker.app/register.

You will not be able to turn on Open Signup if you have any filters in the user list, or if you have any data filters on your User table.

If you are on a version with [Customer Access](/stacker-classic/customer-access/customer-access.md), you will not be able to enable open signup. Please contact [Stacker support](mailto:support@stackerhq.com) if you have any questions on this.
