Authentication & access control

Add sign-in and user permissions

Add sign-in, user accounts, and permissions that keep the right people in and everyone else out.

Is this for you?

Sign-in looks simple and is easy to get subtly wrong. Accounts, password resets, social login, sessions, and roles each have details that matter, and an app that grows past a demo needs them done properly.

For example:

  • Adding Google or Microsoft sign-in to an existing app
  • Giving staff and customers different permissions
  • Replacing a homemade login with a proper provider

What Blue Pixel delivers

  • Sign-in with email, or with Google, Microsoft, Apple, or GitHub
  • An authentication provider chosen to fit, or your existing one reviewed
  • Sessions and tokens handled securely
  • Roles and permissions, checked on the server rather than only in the browser
  • Account flows: sign-up, verification, password reset

How the work goes

  1. Understand who uses it

    Customers, staff, partners: who signs in, and what each may see and do.

  2. Choose the approach

    A managed provider or your own, explained with its costs and trade-offs.

  3. Build and test

    Sign-in and permissions implemented, with tests for who can and cannot reach what.

What helps scope the work

It helps to know:

  • How many kinds of user there are, and how fine-grained the permissions need to be
  • Whether existing users and passwords need to be migrated
  • Single sign-on or compliance requirements from your customers

Questions

Should I build my own sign-in?

Usually not. A managed provider handles most of the hard parts. Blue Pixel helps choose one and wires it in correctly, including the server-side checks a provider cannot do for you.

Can you add Google sign-in to an existing app?

Yes. Blue Pixel’s own site uses Google sign-in, with the code exchange done securely on the server.
