The problem it solves

Building a simple login system for an internal tool usually means paying for a separate auth service or writing code you don't want to maintain. You just need people to sign up with an email and get back in without remembering a password.

Who it fits

Small teams building an internal dashboard or admin portal without a dedicated engineering budget.

How it works

  1. Someone submits their email through a sign-up form
  2. Generates a password and a one-time login token
  3. Stores the new account in Google Sheets
  4. Emails the person their login details and an instant magic link
  5. Verifies the link and logs them straight into their profile
What you get

Sign-ups and logins working without a password

People can sign up with just an email and log straight into your portal through a one-click link, no password needed.

What you get

A working account with password and magic-link access, stored and managed entirely in a spreadsheet.

What you need

A Gmail or SMTP account and a Google Sheets account, alongside your web portal.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
