Add Firebase Authentication Safely
Firebase sign-in setup can become inconsistent across providers and security rules. This skill gives focused guidance for Firebase Auth basics in AI coding sessions.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "firebase-auth-basics" from https://skillstore.io/skills/firebase-firebase-auth-basics.md and its manifest at https://skillstore.io/api/skills/firebase-firebase-auth-basics/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "firebase-auth-basics". I need Google and email sign-in for a React web app.
Expected outcome:
A setup checklist covering Firebase prerequisites, provider enablement, SDK initialization, sign-in flows, auth-state handling, and sign-out behavior.
Using "firebase-auth-basics". Users should only access their own profile data.
Expected outcome:
A rule design explanation that compares the signed-in user identifier with the profile identifier or owner field before allowing access.
Using "firebase-auth-basics". I want to test authentication locally before release.
Expected outcome:
Guidance for connecting the web app to the Firebase Auth emulator during localhost development and switching to production configuration later.
Security Audit
SafeThe static findings are false positives caused by Markdown inline code, sample Firebase configuration, localhost emulator URLs, and official Firebase documentation links. I found no evidence of prompt injection, credential exfiltration, hidden execution, or malicious network behavior in the reviewed files.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Add web sign-in
Plan email, OAuth, anonymous, or email-link sign-in for a Firebase web app.
Protect user data
Connect Firebase Authentication concepts to security rules that check signed-in users and ownership.
Review auth flow
Check whether a planned Firebase Auth flow covers provider setup, user state, and rule enforcement.
Try These Prompts
Use this skill to add Firebase email and password sign-up and sign-in to my web app. Show the setup steps and explain required Firebase configuration.
Use this skill to configure Google sign-in for my Firebase web app. Include provider enablement, SDK setup, auth state handling, and sign-out behavior.
Use this skill to design Firebase rules so users can read and write only their own profile documents. Include request.auth checks and ownership matching.
Use this skill to review my Firebase Auth plan for web, email links, OAuth, anonymous accounts, and rules. Identify gaps and safer defaults.
Best Practices
- Enable only required providers and keep authorized redirect domains limited.
- Use the Auth emulator during local development before production testing.
- Write rules that verify request.auth and resource ownership for every protected path.
Avoid
- Treating client-side auth state as the only access control.
- Leaving broad read or write rules after adding sign-in.
- Using placeholder redirect domains or sample URLs in production configuration.
