How to give a developer access without sharing passwords
Use team invites and limited roles instead of shared passwords, service by service, and know exactly how to remove access and rotate keys when the work ends.
ReadFirebase bundles authentication, the Firestore and Realtime Database options, Cloud Functions, storage, hosting and analytics under one Google project. It is a common backend for Flutter, FlutterFlow and React Native apps, and for many web apps as well. When a Firebase project stalls, the usual issues are less about missing features and more about rules, data design and keeping costs predictable as the app grows.
Owners often reach out after a specific event. The app suddenly cannot write data, a monthly bill is higher than expected, or a security warning arrives from Google about open rules. In other cases the original developer has left, and the owner finds that the Firebase project, the Google Cloud billing account or both are tied to someone else's Google login.
Inside the project, it is common to find collections that grew without a plan, Cloud Functions written in several styles, and environment configuration that exists only on the previous developer's machine.
Developers want to understand both the app and how it uses Firebase. List:
It also helps to mention whether the project uses the Firebase Local Emulator Suite. The emulators let a developer run Auth, Firestore, Functions and Storage on their own machine, so rules and functions can be tested without touching real users or real data. If the repository already has emulator settings in its firebase.json file, say so; if not, setting them up early is a worthwhile first task that makes every later change safer and cheaper to check.
Confirm that you are an Owner of the Firebase project before posting, so you can grant access later without delays. The /tools/handover-checklist-generator helps collect the rest, and /tools/production-readiness-checklist is useful if the app has not launched yet. Then /post your listing at no cost.
Keep the Google account that owns the project to yourself and use these instead:
The guide /guides/give-developer-access-without-sharing-passwords explains invitation-based access in more depth. TakeoverWork helps project owners meet developers, while the terms and payment for any work stay between you and the person you choose.

ReadA calm, ordered plan for the day your developer goes silent: protect the domain and email first, then hosting, code, data and money accounts.
ReadYour AI-built prototype works in the demo. These 25 checks, grouped into ten areas, cover what usually needs attention before real users and real money arrive.
ReadA common cause is test mode rules reaching their expiry date. Test mode allows open access only until a set date, after which requests are denied. The fix is to write proper security rules, not to extend the open period.
The web or mobile config values that identify your project are designed to be public. Protection comes from security rules and App Check. Service account keys and server API keys, however, are secret and must never ship in an app.
Some features, including deploying Cloud Functions, require the pay-as-you-go Blaze plan. Set budget alerts in the Google Cloud console so you hear about unexpected usage early.
Open the project's Users and permissions settings and invite them by email with a suitable role. Firebase access is managed through Google Cloud IAM, so you can choose narrower roles than Owner.
It is possible, but it is a bigger job than fixing what you have, because auth, data structure and functions all need replacing. Most takeovers keep Firebase and improve how it is used.
