I don’t want a data source rather a unique userID without email. ---

Why don’t you want a data source? You have to store the username and password somewhere to verify their login info. If not, then you can’t enforce a unique username. And you also can’t check passwords to see if they are correct. You do not have to use email addresses for what I’m suggesting. ---

Can data source update, delete, add username and password? ---

actually sir, I saw that firebase authentication is going to stop in Aug 2025, but I want my app to work even after that. ---

> [@schoolwork7002lro2tb](#): > > I saw that firebase authentication is going to stop in Aug 2025 This is not true. Google does have plans to deprecate a feature related to authentication later this year but authentication itself will still work for the foreseeable future. > The following three Firebase Authentication features are impacted by the shutdown of Firebase Dynamic Links on August 25, 2025: email link authentication for mobile apps, OAuth flows for Android apps using older versions of the Authentication SDK, and Cordova OAuth support for web apps. In order to use these features after the shutdown of Dynamic Links, migrate to use a newer SDK version and complete some additional steps. > > For specific information and migration guidance, visit the [Dynamic Links Deprecation FAQ](https://firebase.google.com/support/dynamic-links-faq#impacts-on-email-link-authentication). ---
