### Email-Link login
244+
Enable email-password login in your firebase instance, and flip the "E-mail link" switch.
245+
246+
This login type allows your users to login without providing a password. They can simply click a link
247+
and get redirected to the app. The app may even run on a different device.
248+
249+
Enable dynamic links, as described in the [Dynamic Links readme]("./INVITES_DYNAMICLINKS.md"), because the user
250+
that receives the link will need to be redirected to your app.
251+
252+
#### iOS configuration
253+
- Specify the bundle id of your app in the Firebase console.
254+
255+
#### Android configuration
256+
- Specify the package name of your app in the Firebase console.
257+
- Upload the SHA-1 and SHA-256 of the (debug) signing certificates to the Firebase console, as described in the [Dynamic Links readme]("./INVITES_DYNAMICLINKS.md").
258+
- Also add an `android:host` for the `emailLinkOptions.url` to your `app/App_Resources/Android/AndroidManifest.xml` file as described in that readme.
