Firebase Auth Integration in Wrexham
Integrating Firebase Authentication into Wrexham applications, where signing in and being allowed to see something are separate problems. Authentication tells you who a user is; security rules decide what they can read — and an application that adds the first without writing the second gives every signed-in user access to everybody else's data.
Why this comes up
The problem
Users log in successfully, and any authenticated account can read the entire database.
What you get
What we deliver
- Security rules written alongside authentication rather than left permissive
- Rules tested with the emulator, including as users who should be refused
- Custom claims used for roles rather than storing them where clients can edit them
- Token verification performed server-side wherever a decision depends on it
- Sign-in methods chosen deliberately, since each carries its own recovery path
- Account linking handled, so one person does not end up with several accounts

Firebase Auth Integration in Wrexham — common questions
- Is authentication enough on its own?
- No — it only establishes identity. Without security rules restricting what each user can read and write, being signed in is sufficient to reach everything, which is the most common serious mistake in Firebase applications and rarely noticed from inside the product.
- How should rules be tested?
- Against the cases that should fail. The emulator lets you assert that one user cannot read another's records, and those negative tests are the ones with value — a rule set only ever tested by its author signing in tells you almost nothing.
- Where should roles be stored?
- In custom claims on the token, not in a document the client can write to. A role held in an ordinary database record can be altered by the user it describes unless rules prevent it, and that is a promotion to administrator waiting to happen.
- What about duplicate accounts?
- They arise when someone signs in with a different method than before — email one time, a social provider the next. Deciding how accounts are linked before launch avoids a support queue of people who cannot find their own data and have no idea why.
- Do you work with businesses across Wrexham?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Wrexham and the surrounding Wrexham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Wrexham businesses do you usually work with?
- Manufacturing and food production systems for businesses on the border serving North West England customers. Beyond that we work across Manufacturing, Food Production, Logistics, Higher Education and Retail.
- Do you cover the areas around Wrexham?
