Firebase Dynamic Links shut down on August 25, 2025. Every page.link and custom-domain Dynamic Link stopped working, and email sign-in links in mobile apps that relied on them need a newer setup.
**Short answer**
If you only need to open the app from a link once it is installed, use Android App Links and iOS Universal Links on a domain you control. If you also need deferred deep links, click analytics or short links, Firebase points to other deep-linking providers. For email link sign-in in a mobile app, update the Firebase Auth SDK, remove dynamicLinkDomain, and set linkDomain if the project uses a custom Firebase Hosting link domain. Then ship app updates.

## **What broke when Dynamic Links shut down, and the fix**
1. 01 ### **Shared and marketing links lead nowhere**
> “All links served by Firebase Dynamic Links (both hosted on custom domains and page.link subdomains) will stop working and you will no longer be able to create new links.” [**Firebase, Dynamic Links deprecation FAQ**](https://firebase.google.com/support/dynamic-links-faq) Links on page.link, or on a custom domain served by Dynamic Links, no longer open the app. For links that only open an installed app, Firebase recommends App Links and Universal Links; for deferred deep links or click analytics, it names other providers such as Branch and AppsFlyer. Update every link you control.
2. 02 ### **Email link sign-in in the mobile app fails**
> “you will need to upgrade to the latest Firebase Authentication SDKs and migrate to the new solution in order to continue using these actions” [**Firebase, Dynamic Links deprecation FAQ**](https://firebase.google.com/support/dynamic-links-faq) Email link sign-in for mobile apps used Dynamic Links to open the app. Update the Firebase Auth SDK, remove dynamicLinkDomain, and pass linkDomain in the action code settings if the project uses a custom Hosting domain; otherwise Firebase picks the default Hosting domain.```
const actionCodeSettings = {
url: 'https://www.example.com/finishSignUp',
handleCodeInApp: true,
iOS: { bundleId: 'com.example.ios' },
android: { packageName: 'com.example.android', installApp: true },
// The domain must be configured in Firebase Hosting and owned by the project.
linkDomain: 'custom-domain.com',
};
```
3. 03 ### **Old app versions still call the API**
> “The SDKs themselves will not cause your app to crash. Your application code must handle the changed API responses.” [**Firebase, Dynamic Links deprecation FAQ**](https://firebase.google.com/support/dynamic-links-faq) Creating short links and reading the link that opened the app now return errors or empty data. The Firebase SDKs don’t crash on this, but app code that expects link data can break or silently skip the feature. Remove the calls and ship an update.
4. 04 ### **The link data needs exporting**
> “once the Firebase Dynamic Links service is shut down any .page.link domains will no longer be available.” [**Firebase, Dynamic Links deprecation FAQ**](https://firebase.google.com/support/dynamic-links-faq) Also check: Firebase marked domains and link metadata for deletion at the shutdown, and page.link domains can’t be kept. If you need the old link data, check what Firebase’s export guide still offers.

Questions
## **More on this error**
**Can I keep my page.link domain? **+
No. Firebase says .page.link domains are no longer available after the shutdown, so links need a domain you control.
**Does password reset still work? **+
Firebase says email link sign-in, password reset and email verification keep working, once the app uses the latest Firebase Auth SDK and the new setup.
**Can you fix it for me? **+
