# Creating your account and signing in

Getting started · Web and mobile · 3 min read · updated August 15, 2026

**Sign up once with your company name and email, and you own a company that everyone else joins by invitation — signing in afterwards with a password, a Google, Microsoft or Facebook account, or biometrics on the phone.**

The first account in a company is the owner's, and it is the only one that
starts from nothing. Everyone after that is invited into the company it created.

## Starting the company

Signing up asks for four things: your company's name, your name, an email
address and a password. That is enough to create the company, make you its
owner, and seed it with a room and task library you can start quoting from the
same afternoon — see [Your room and task library](/docs/your-room-and-task-library).

Two things are set from your surroundings rather than asked for. Your time zone
comes from the device you signed up on, so quotes and visits are dated in your
own zone from the first one. Your language follows your browser, and can be
changed later.

If you signed up from the phone app, the same form is there, and a verification
step runs in a sheet for that one moment — it is the only part of the app that
opens a web view.

## Signing in

You can sign in with your password or with a Google, Microsoft or Facebook
account. These are credentials on one account rather than separate accounts, so
you can mix them freely: sign up with a password and add Google later, or the
other way round. Losing access to one never locks you out while another still
works, and disconnecting one that has been compromised signs out every other
session at the same time.

A few details that matter when something goes wrong:

- **Repeated failures, not normal ones, get a bot check.** Signing in correctly
  stays one click. Only after several failed attempts does a challenge appear.
- **Your sign-in session lives on the server**, with a secure cookie that
  browser scripts cannot read. Offline mode is separate: the browser may keep a
  small recent working set on the device, such as customers, quotes, invoices,
  worksheets and unfinished quote or inspection work. It is separated by
  signed-in user, company and location, and it cannot be used to sign in. On a
  shared computer, sign out when you finish and clear BlastoClean's stored site
  data if you also want to remove the device copy.
- **Forgot your password** sends a reset link to the address on the account.
  If your account has no password — because you only ever used Google — signing
  in with Google is the way back, and setting a password afterwards is optional.

## On the phone

The iPhone and Android app signs in to the same company with the same
credentials, and stores its session in the platform keychain or keystore rather
than in a file. Once you are in, you can turn on **biometric app lock** in
Settings: Face ID, Touch ID or Android biometrics, with the device passcode as
the fallback for the times a fingerprint will not read.

The **Advanced** expander under the sign-in button points the app at a different
deployment. Almost nobody needs it — it exists for staging and local
development, and the app talks to the production server without it.

## Adding your team

New people are invited from **Settings → Team**, which is also where roles are
set and access is taken away again. What each role may do, and what happens the
moment you change one, is in
[Team, roles and permissions](/docs/team-roles-and-permissions).
